## Version 9.04 (2011-08-05)

This is the fourth full release in the stable 9.x series.

This release includes fixes and solutions for a number of serious problems from the earlier 9.x releases and so we strongly encourage those using earlier 9.x releases to upgrade to this new version, to reap the benefits of those fixes.

In addition, those still using Ghostscript 8.71 and earlier should begin migration to 9.x soon since many improvements, features and fixes from the 9.x versions are impractical to back-port to these legacy versions.

Highlights in this release include:

- Transition source base to git source control - not a big deal for most users, but an important change for those develop Ghostscript and GhostPDL.
- This release introduces flexibility for controlling color based upon the graphic object type. In particular, it is now possible to specify unique output ICC profiles and rendering intents for vector graphic, image and tex portions of a document. It is also possible to override source color specifications and use specified ICC profiles and rendering intents for RGB and CMYK vector graphics, images and text portions of a document. Finally, DeviceGray source colors can now easily be specified to map either to K only or composite CMYK when the output device supports CMYK colorants.
- New tiffscaled8 and tiffscaled24 devices. Add new tiffscaled8 and tiffscaled24 devices, copied and modified from tiffscaled. These output greyscale and 24bit rgb instead of tiffscaleds mono output. MinFeatureSize is ignored for these devices as it's meaningless for contone output. Downscaling is also now supported for png16m and pnggray, and a new pngmonod device has been implemented which uses grayscale rendering internally and then downscales/min_feature_sizes/error diffuses to monochrome.
- The PDF interpreter will now try continue interpreting a PDF after encountering an error in a stream. The previous bevahior can be reinstated by passing -dPDFSTOPONERROR to Ghostscript.
- Re-enable x11alpha as the default device on Unix systems, now that compatibility problems between anti-aliased output and transparency are resolved.
- Update libjpeg to version 8c.
- Experimental Text output/extraction device

  The txtwrite device has undergone some development, and now has genuine functionality. It accepts any input format which GhostPDL supports, and uses a combination of methods to try and determine the Unicode values for any text contained in the document.

  The code descends a hierarchy of methods in this process, starting with the most reliable and only falling back to less reliable methods when better methods fail. The current hierarchy is as follows:

  1. ToUnicode CMaps (PostScript or PDF) or GlyphNamesToUnicode tables (PostScript).
  2. Glyph names of the form 'unixxxx'.
  3. Glyph names defined in the Adobe Glyph List document.
  4. Input character code.

  Method 1 is highly reliable, method 4 is a best guess and not terribly reliable, though it will work for many files. It is probably most reliable for PostScript and PCL files.

  The device currently has one parameter 'TextFormat' which controls whether the output is Unicode text reflecting the layout of the original document (-dTextFormat=0) or a format intended for use by developers which includes the Unicode text and some formatting information, such as the size and position of the text, and the font in use (-dTextFormat=1).

  Note that his device does not do OCR (Optical Character Recognition) it is not capable of finding 'text' which is part of an image. However it will recover the 'invisible' text from PDF documents which have been scanned and OCR'ed by Acrobat for searching. Such text has a render mode of 3.

  This is the first release of this code and is very much an alpha release, we expect problems.

  In particular the TextFormat=0 output is likely to be incorrect, and will only work with top-to-bottom left-to-right text. It will probably also be confused by landscape documents printed on portrait media.

  TextFormat=1 should be more reliable, but there may be cases where text is dropped from the output. Text in PostScript documents using charpath is not yet supported for example.

  We do encourage feedback on the state of this device, and would be interested in hearing what kind of output would be useful for developers using TextFormat=1. For now, however, please do not raise bugs through Bugzilla, instead please send feedback to the gs-devel mailing list.

- Experimental Unicode/UTF8 Support on Windows

  This release introduces some experimental build-time optional support for UNICODE pathnames on Windows. Essentially this works by following the model that Linux (and MacOS) have followed for years.

  If this code is enabled, then the way ghostscript handles command lines, registry settings, file accesses and other api calls with top bit set characters in (i.e. codes >= 128) will change. The net benefit of this change is that ghostscript will now be able to cope with accessing files with unicode characters (i.e. codes >= 256) in their pathnames.

  This behaviour is all completely transparent to users, with the exception of those calling the gsapi functions with strings including 'extended ascii' (i.e. characters with codes >= 128 and <= 255). These characters include accented latin characters, such as u + umlaut, a + grave etc. The changes required for code that is affected by this are relatively minor, but as this is a change to the current API, we are announcing it in advance, and inviting comments.

  As of the 9.04 release, the code is disabled. For those who wish to experiment you will need to build Ghostscript from source, and either pass USEUNICODE=1 when you invoke nmake or edit psi/msvc.mak to remove the /DWINDOWS_NO_UNICODE option from CFLAGS.

  WARNING: Our intention, subject to feedback, is to enable this by default in near-future releases (hopefully, the next major release). If you make use of the affected APIs you should be prepared for the change to occur - be aware, however, that the current code is experimental and, depending on the feedback we get, maybe subject to change.

  NOTE: this whole change refers to file paths, command line parameters and so on - it does not imply that we have unilaterally extended Postscript to understand UNICODE.

  More details:

  To give an example, suppose we have a file 'EXAMPLE' we'd like to invoke ghostscript on, where 'EXAMPLE' is actually a string that contains some characters with codes >= 128.

  On Linux (or MacOS X), when ghostscript is called from a shell, e.g.

  gs EXAMPLE

  the command is UTF8 encoded; this means that characters with codes < 128 are left unchanged, and characters >= 128 are encoded into multiple bytes. This encoded string is then passed to the standard 'main' entrypoint in the gs executable.

  Ghostscript proceeds internally without any special handling of these multibyte characters at all. When it comes to access files it therefore passes out the UTF8 encoded strings to the standard OS file handling routines. These routines are designed to take pathnames in UTF8 format, and thus the files are accessed as normal.

  If the Ghostscript executable outputs these (or other) strings to its stdout, the shell again converts the output from UTF8 back to unicode in order to display it.

  The net effect is that the caller can seamlessly pass in unicode filenames, has his fileaccesses work out and gets unicode output without the core of ghostscript ever having to worry about it.

  The code change discussed here endeavours to make Windows follow the same pattern as closely as possible.

  When Windows executables are invoked, they can either be called through an 'ascii' entrypoint (main), or through a unicode ('wide') entrypoint (wmain). The difference is invisible to the caller, except that unicode executables can accept characters >= 256 in their invocations.

  The new code changes ghostscript from being an ascii executable to being a unicode one. The Windows specific outer layer takes the unicode command string and UTF8 encodes it before passing it to the ghostscript core.

  Similarly, the Windows specific filing system calls are updated to accept utf8 encoded strings from the core, and to convert them to unicode before operating on them.

  The Windows gui app (gswin32.exe, NOT gswin32c.exe) is also updated to convert stdin/stdout between unicode and utf8 as appropriate, allowing unicode strings to be copied/pasted to/from other apps.

  All of this should be completely transparent to the user, and no code changes should be required. The one area where changes may be required are where ghostscript is invoked through the gsapi functions.

  Currently, on Linux (and MacOS X) any strings sent over the gsapi are assumed to be utf8 encoded (and thus can represent any Unicode character). On Windows, they are assumed simply to be in extended ASCII (and can therefore represent any character < 256 in the current codepage). With the proposed change, Windows will move to be in step with Linux. No differences will be caused to anyone who only uses chars <= 128, but those people using character codes between 128 and 256 (or indeed wanting to use higher codes) will need to utf8 encode the strings before calling gsapi functions.

  Such encoding/decoding is a very simple process, and code for both directions can be found in psi/dwmain.c, psi/dwmainc.c and psi/dwtext.c.

  Again, we welcome feedback on this feature, in this case problems or suggestions about the implementation can be submitted via Bugzilla but for detailed discussion about the approach for which we opted, it would be more beneficial discuss it (preferably) on our IRC channel #ghostscript on freenode.net, or on the gs-devel mailing list.

> The invocation/file given in the bug uses banded rendering (clist).

> Add functionality to the textwrite device.
> The existing textwrite device was a null device which emitted nothing. This
> version actually extracts text from input documents. It uses ToUnicode CMaps,
> GlyphNames2Unicode tables and glyph names in an attempt to map incoming text into
> Unicode (UTF-16) values.
> It currently has one switch 'TextFormat' which has two possible values, 0 or 1.
> -dTextFormat=0 outputs a 'layout' representation of the original text. This
> will attempt to produce text output which is similar in appearance to the original.
> -dTextFormat=1 simply emits all the text as it is encountered, along with information
> about the text state. It outputs the Font name, point size, rendering mode and
> writing mode (WMode) as well as the start and ending co-ordinates of the text on the page
> and the Unicode string representing the text. This is intended for those who
> would like to manipulate the text into other formats.
> The Adobe Glyph Names list is now embedded in the executable twice, in two
> incompatible forms. A future enhanvement will be to only embed the list once.

> Fix Bug 692057, 'hang' while converting mask->rectangle list.
> Previously the clip accumulator code would attempt to add a new
> rectangle would always search backwards from the tail of the
> list when looking for a new place to insert a rectangle.
> This works well when rectangles are coming in at (or near) the
> end of the list. For cases where this doesn't happen we quickly
> break down to O(n^2) operation.
> The example file on the bug shows one such circumstance, where

> in as '8 bit columns'. The first column accumulates nicely,
> subsequent ones do not.
> The fix here, as suggested by Chris Liddell, is to store the
> 'last insert point', and to search from that. Locality of

> Bug 691118: Fix radial shading bug
> Bug 691118 describes a bug with radial shadings in a PDF file.
> Back in r7982 (git 69a43b0) (16 May 2007) Igor introduced some cunning
> code to speed radial shadings. It would spot that the shading was large
> in comparison with the area being filled, and produce a smaller,
> equivalent shading.
> Essentially, it would take the destination rectangle, and figure out
> where in the shading the 'extremes' of that rectangle would come from
> (allowing for distortion in shape generation) and ensure that the newly
> generated shading covered the same area.
> Either the corners of the rectangle could be extremes, or points on the
> side. The code for the points on the sides was broken due to a typo
> causing the X and Y cases to be switched.
> All that is required to solve the bug is to change the == to !=.
> In researching the problem however, I recommented lots of the code to
> make it more comprehensible (to me at least!) along with introducing
> some temporary variables to make it clearer and avoid needless
> recomputation of values. I am committing this as I believe it's a step
> forward for the code, even though it doesn't actually make a
> difference.
> 48 differences in non-pdfwrite/ps2write tests. 11 in pdfwrite, 17 in
> ps2write. Checked with bmpcmp, all unnoticable to the naked eye, so

> Fix bug 691152; gradients appear 'stepped'.
> The original bug report was that tiffsep and tiff24nc give noticably

More type 3 font madness
Use the device level 'PS_accumulator' flag in various places instead of
the more kludgy test against penuym->pte_default being NULL.
If we don't get a glyph name back from the interpreter (PCL) then invent
one instead of giving up with an error.
If we are not a type 3 accumulator, then don't undo the factor of 100
scaling applied to the device width and height, we only do that for PS.
Add a routine to return a special 'initial' matrix during the course of
type 3 accumulation. The PCL stick font uses this to set the line width
and we need to account for various PS/PDF scaling which will otherwise
be ignored.
Make sure we don't try and accumulate a charproc when its being run for a
charpath operation.

Type PCL fonts again.
Put back the matrix scaling in pdf_text_set_cache, even though the matrix
shoudl always be the identity here when running PCL. Best to be safe.
set_charproc_attrs emitted a 'd1' setcachedevice, but didn't check if
the glyph was flipped. For PCL this led to ury being less than lly, and
so the glyph was elided. Added check to make sure these are correct. This
required removal of 'const' from an arry as well.

More type 3 changes
Don't scale the CTM by 100 (done for FreeType) when handling PCL fonts
in install_charproc_accum, set the boolean to complete_charproc_accum so
that we don't 'undo' the factor of 100 scaling when the font is PCL.
Add code to set_charproc_attrs to determine whether this is a 'scale 100'
(ie PostScript) type 3 font or not, if its not then don't undo the scaling
by 100 of the CTM.
When accumulating a chraproc, before setting the CTM to identity matrix
also set the current point to 0,0, which ensures that that the current point
doesn't get baked into the character description. Also invalidate the
'char_tm' txy_fixed_valid member of the graphics state, this will force
a recalculation of char_tm using the new identity matrix.

More PCL type 3 improvements
Add code to initialise the returned character code, so that the charproc
is assigned the correct character code. Further test for PCL fonts in
pdf_text_set_cache and don't try to use a show enumerator to get the
'output_char_code' when we are doing PCL, instead use the one from the
text enumerator 'returned' structure. Normally this would not be valid
yet as this is filled in after we've completed the 'show', but we
set this before startig the show, from the text string, so that it will be
valid.

Bug 692218: Incorrect CIDtoGIDMap length causing crash.
In pdfwrite's pdf_convert_truetype_font_descriptor() function,
the lengths of both the CIDtoGIDMap and the CIDSet were being set
to the number of in use CID's in the font, whereas they need to
be, and were being filled, as being LastChar + 1 entries long.
As well as memory corruption, the contents would have been wrong,
too.

Fix Bug 692216. Remove zero height traps from shadings.
The simplified file in Bug 692216 shows a division by zero error when
filling a trapezoid with zero height. The fix is simply to update
the code not to draw zero height traps.
This should be safe as any fill adjustment is done well before this point.
The cluster shows just one difference. Looking at it in a bmpcmp it does
look suspicious, but it's not clear whether it's a progression or a
regression. Ken informs me he's seen the same differences before with
unrelated changes, so perhaps it's an indeterminism.
The code seems more sensible this way round anyway.

Pacify valgrind (and improve performance?) with tiny change.
A tiny change to gxclrast.c where we initialise state_tile.size.{x,y}.
This stops valgrind giving warnings. While the code works OK without

expedient of setting the variable to 0 to start with.

Fix clipping problems with composited pattern clists.
When using a clist to fill a clipped area with a pattern, the current
code can drop the clipping device out of the chain. This change solves that
problem.
When we create a new compositor, we generally want that compositor to become
the top device in the chain, so all new drawing commands go to it. In the
pattern clist case however, we don't create a new compositor - we reuse an
existing one. It's important in this case *not* to take this as our new
target, otherwise the higher devices in the chain (such as the clipper
device) are lost.
This was shown when rendering pattrans_big.pdf at 300dpi banded to the pkm
device.

When run with valgrind on:
gs -sDEVICE=pbmraw -r300 -dMaxBitmap=100000000 -o out.pbm Bug690189c.pdf
Valgrind complains that params.GrayBackground is used without being
initialised. We fix this here by amending gs_trans_mask_params_init.
In so doing, we note that in zbegintransparencymaskgroup we were setting
params.ColorSpace, only to call gs_trans_mask_params_init and have it
overwrite it. To avoid confusion we therefore remove this needless init.

Fix for reference counting issue of the compositor device at
the end of the clist playback. In most cases, the compositor rc
should be 1 at this point and so the device is closed and then
freed. The case, when it is not 1 is when we have a pattern
that has a transparency and is stored in a clist. In this case
the target for the pattern clist device is the main pdf14 device and
we increment the rc during this assignment. So, when the
playback completes, the rc of the compositor is 2. We do not
want to close and free the compositor, since it is part of the
main clist that we have going on. Instead we only want to
decrement the rc. The test file pattrans_big.pdf is now
handled correctly but has a rendering/tiling issue it appears.

A couple of weeks ago, I applied a wild stab in the dark to solve a problem
that I cannot now locate. Having discussed it with Michael it seems that this
was (at best) just masking another problem (the incorrect ref count
initialisation of compositors). This has been fixed, so my faulty attempt
can be backed out.

replaced by an assert when we have such things.

Initial commit of work so far on getting the pattern transparency
clist code working. Much of this comes from work that Ray and I did
for customer 532. The remaining portion of the work is primarily
in pdf14_tile_pattern_fill in gdevp14.c, where we need to make
sure that the group that we are going to push is the intersection
with the rect from trans pattern since we only use the part that we
drew into in the pattern creation and not the whole group buffer. I
had not worked on this in a few weeks so I don't have more details
right now. I will spend a day on it this week to see exactly what
remains to be done.

Address bug 692211; byteswap.h not present on FreeBSD.
After googling it seems like the correct thing to do is to use gcc builtin

Fix for MT crashes in lcms
It turns out that lcms is can not safely share
profiles between threads when creating links. This
was fixed by placing a mutex lock around the profile
creation. It also turns out that lcms can not
use the same link to do transformations between threads.
This was solved by disabling the shared cache between
the threads. Finally there was a race condition in
reference counting the device ICC profile in the pdf14
device. Also, this commit includes a fix for a memory
leak in the pdf_mask object in gdevp14.

Change in device ICC profile handling
This is the major portion of the code needed to achieve object dependent
color management. This fixes the problems that existed in the
previous code with the device parameters and introduces an array of
ICC profiles in the device structure. The code was cluster pushed and
showed some very minor differences in a couple files but they appear to be
OK with bmpcmp. I still need to do further testing to verify that all the
functionality is correct (e.g. make sure setting the text profile properly
affects the text only). In addition, the rendering intent options need to be
implemented.
I also need to check that nothing was broken with respect to MT
rendering and some of the devices that are not tested with cluster
pushing (e.g. the display device and the x11alpha device).

Modified math_.h to use our hypot().
The system hypot() function gives slightly different results on Linux vs
Mac OS X systems for same input values. This minor difference results
in rendering variations in some files, confounding the regression
test system.
This revision changes math_.h to use our hypot() in all cases instead
of the system one (previously our function was used on those platforms
where there was no system hypot() function).
Testing by Robin shows that our function is faster than the system one,
so another reason to make this change.

Change PSI so -Z! works by default in debug builds.
Previously, the -Z! option (to show the name of each PS operator as it is
executed) has only been available in DEBUG builds that specifically use
the DEBUG_TRACE_PS_OPERATORS option. This change ensures that it is available
in ALL debug builds, and in any release build where the
DEBUG_TRACE_PS_OPERATORS symbol is predefined.
The reason for historically having it as a separate option was because
checking for whether the ! debug flag was set on every operator was felt
to be too large an overhead. I have arranged the code so that this overhead
is minimised now - in debug builds we only get the extra overhead when
the -Z! is specified on the command line.
In normal release builds there is no change to the overhead. In release
builds with DEBUG_TRACE_PS_OPERATORS, the same overheads apply as in
DEBUG builds (that is a small additional overhead when -Z! is not used
and a larger one when it is).

Pacify valgrind (and improve performance?) with tiny change.
A tiny change to gxclrast.c where we initialise state_tile.size.{x,y}.
This stops valgrind giving warnings. While the code works OK without

expedient of setting the variable to 0 to start with.

Add LAND_BITS define to landscape mono halftoning code.
The monochrome halftone thresholding code relies on collating incoming
scanline data into 'scancolumn' buffers. When we have 16 bytes in these
buffers, they halftoned and flushed through copy_mono.
copy_mono would prefer to work with longer than 16 byte runs, so we
remove the hardcoded 16s from throughout the code and replace it with
a #defined value. A side effect of this is that the code becomes
slightly clearer.
Sadly, it seems this doesn't give the expected speedups; testing here
indicates that both 32 and 128 run slower, possibly due to cache effects.
Nonetheless we commit the code in case inspiration strikes us later on.

Valgrind complains that params.GrayBackground is used without being
initialised. We fix this here by amending gs_trans_mask_params_init.
In so doing, we note that in zbegintransparencymaskgroup we were setting
params.ColorSpace, only to call gs_trans_mask_params_init and have it
overwrite it. To avoid confusion we therefore remove this needless init.

Significant change in how the device profile is handled in ghostscript. This
change adds in a new device procedure called get_profile, which is going to
typically be set to gx_forward_get_profile or gx_default_get_profile. Most
internal devices like the pattern accumulator, the clip device, memory devices,
will use the gx_forward_get_profile procedure. In this way, the profile is
typically only maintained by the the target device. The gdevp14 device is the significant internal device that takes special handling due to the way that it
can change its ICC profile based upon the current transparency group color space. The get_profile procedure also passes along information about the object
type so that we will be able to easily add in the device dependent color
management. The rendering intent, which can also be object dependent is also returned by the call. This change has been cluster tested and showed no differences.

Retain or bias the reference count of the rop texture device.
The image code was using the rop texture device without any reference
counting, explicitly freeing the device when it was done. That was
fine if the device was the only device in the chain, however, linking
in other devices could lead indirectly to unintended freeing of the
rop device. A crash was seen in the the XL test file C705.BIN but
only with halftoning at particular resolutions like 72 dpi. We did
not study why the crash was limited to particular resolutions and
devices.

Solve windows debug build crash on exit with cups device.
It seems that the cups device takes it upon itself to close the output file
rather than leaving it for the ghostscript core to close as every other
device does. This upsets the windows DLL file handling.
The solution is simply to remove the lines that close the file. I've
checked both with Till and Ken, and they concur. Thanks.

Change error return to remove confusion over meaning.
When we encounter a font whose charstring has been replaced with a PS
procedure, we were returning FT_Err_Invalid_File_Format, and using that
as a hint we should try to execute it as a PS procedure. This
turns out to be problematic as it is also the error return generated by
Freetype for an invalid charstring. In the case of an invalid charstring
we should fall back to the notdef, not attempt to execute the object as
Postscript.
So, change the error return value that *we* generate, and subsequently
check for, to FT_Err_Unknown_File_Format, which FT should never,
normally, generate during glyph interpretation. This means, in this
case, we correctly identify a failed attempt to interpret a charstring,
and use the notdef fallback - instead of, eventually, throwing an
error.

Fix for reference counting issue of the compositor device at
the end of the clist playback. In most cases, the compositor rc
should be 1 at this point and so the device is closed and then
freed. The case, when it is not 1 is when we have a pattern
that has a transparency and is stored in a clist. In this case
the target for the pattern clist device is the main pdf14 device and
we increment the rc during this assignment. So, when the
playback completes, the rc of the compositor is 2. We do not
want to close and free the compositor, since it is part of the
main clist that we have going on. Instead we only want to
decrement the rc. The test file pattrans_big.pdf is now
handled correctly but has a rendering/tiling issue it appears.
This commit (from the patt_trans_clist_branch) has been cherry-picked
to the trunk to solve the SEGV in bug #692160. This leaves pdf14
compositors leaking though.

Stop compiler turning for loop into memset in halftoning code.
The msvc compiler cleverly spots that a for loop can be turned
into a memset. Unfortunately it can't know that the values for
which the loop is called are normally so small that the calling
of the function costs more than simply doing the stores.
The fix is to cast the pointer to which we are storing to be
volatile. This saves a significant chunk of runtime for:

Fix for bug 692081. Antialiasing patterns results in white holes.
gx_default_copy_alpha simulates alpha by weighted average of RGB values.
When the alpha value is zero, the current implementation reads the current
background value, and just writes it back. This has the effect of making
any device that watches what devices get written to think that that pixel
is solid. (One such device is the pattern tile device where it collects what
pixels have been marked, and what haven't).
The CORRECT way to do this is to stop the line accumulation at that point,
flush everything to there, then start again a pixel later.
Doing this solves the bug, and causes no cluster changes.

Fix for bug 692152.
We 'bend' the size of pattern tiles, against the spec, ostensibly to better
match Acrobat. The fix here is simply to avoid such bending in the case where
TilingType is 2. According to the spec, TilingType 2 says specifically not
to use the same device pixel size for every repeat of the pattern, and that
is exactly what we were doing.
This cures the original bug, and produces 464 changes in the cluster tests.
Some (like ps3cet/18-02B.PS) are clear progressions. Others are less obviously
improvements, but comparison with Acrobat (and discussion with Ken/Chris)
shows that it's no worse than before, just 'different'.

Further movement toward getting fast thresholding operations working for CMYK output devices. Addition of special op to detect if a device is a planar type, creation of threshold screen for all the planes and spatial resampling of color input to output resolution for portrait case.

rebuilt the xref table when offset == 0 but generation != 0.

possible. Bug 692159.

Add a fallback check for libpaper support.
Older versions of autogen appear to have a bug which causes the AC_CHECK_LIB
macro to mis-identify the libpaper development library as being present when
it is not.
So add a second check check based on the presence of paper.h using
AC_CHECK_HEADER().
No cluster differences expected.

Instead of searching for %%EOF marker (which is often damaged) and browsing the
file backwards, search for 'startxref' and take the next token as an xref
position. Besides fixing the reported bug, this greatly simplifies the search
for xref position. Bug 692153.

Fix (pdfwrite) : Restore TT->CIDFOnt conversion
When creating PDF/A output, the Acrobat pre-flight tool throws out subset TrueType fonts
which are symbolic. Its not clear why, since the spec says that subset TrueType fonts
are permitted and does not require any additional information (such as /CharSet for
type 1 fonts).
If we instead create a CIDFont with a CIDSet, then the pre-flight tool is happy (and
also, usefully, doesn't complain about multiple CMAP subtables), so here we spot
that there is no preferred Encoding (always the case with Symbolic fonts) and make
the conversion.
No differences expected.

Fix for PCL when NumRenderingThreads > 0. PCL uses a memory allocator that is
not thread safe (chunk memory) but the mt rendering needs a thread safe base
allocator since the main thread may be allocating as well as the rendering
threads. This problem was seen with a couple of 'performance' documents, but
could fail on any document. Bug 692111 for customer #661.

Fix PostScript colour handling
Bug #692116 "gs crash while executing stop operator"
The problem was caused by a mismatch between the graphics library and the PostScript
interpreter. When executing setcachedevice the graphcis library can set the colour
space to DeviceGray. Because it is unaware of the 'higher level' members of the graphics
state which belong to the PostScript interpreter it does not, and cannot, set the
*PostScript* graphics state colour space to the same space.
Normally this does not matter, because after the glyph is complete the colour space is
restored. However, if a currentgray/currentrgb/currentcmyk operator is executed after
the graphics library has set the space to DeviceGray, but before it has restored the
space, then the PostScript space will be incorrect. This leads to the PostScript
handling trying to access more elements from the stack than 'currentcolor' put there
(currentcolor uses the underlying space, not the PostScript space), and causes errors.
There isn't a really good way to handle this, because we can't put information about
the PostScript state into the graphics library. So I've chosen to check the underlying
colour space when processing currentgray etc, and if the space in the graphics
library is DeviceGray and does not match the expected PostScript space, then instead
of raising an error we proceed as if the PostScript space had been DeviceGray all
along.

Fix (colour handling) : crash when executing 'stop'
This is part of the fix for bug #692116. The crash in that report is caused because the
continuation procedures for the colour handling are sometimes pushed with a
push_mark_estack where the opproc has a value of 0. This is not valid and I always
intended to fix it, but forgot.
This changes all uses of push_mark_estack so that the opproc is set to a valid routine
which does nothing, thus solving the crash and exposing the real problem. The only
reason we get a crash is because we are executing stop as part of the error handler,
because currentgray returned an error.
No differences expected.

Fix for x11alpha device when the source file has transparency. Two issues existed. One, found by henry, was that the target device of the x11alpha device was not inheriting the icc profile of the x11alpha device. The other was that the x11alpha device was using the bbox compositor procedure, which has some operations in it related to checking if the device has a target and the pdf14 device will target the target of the bbox device. This is not what we want for the x11alpha device. This should fix a lot of the x11alpha bugs Basically any source files that had transparency would have failed prior to this fix.

Fix (pdfwrite) : Not using ToUnicode CMaps under some conditions
Bug #692119 "Cannot copy text from Ghostscript generated PDF/A document"
The PDF interpreter converts ToUnicode CMaps into GlyphNames2Unicode dictionaries, to
do this it uses the Encoding to convert the character codes into glyph names. Of course
for CIDFonts we don't want to do this, and so when there is no Encoding we instead
put the Unicode value directly into the dictionary using the CID as an index.
If the font has no Encoding (which is optional in PDF) then we do the same for a
regular font. However, by the time pdfwrite sees the font we have had to add an Encoding
as its not valid for us to define a regular font with no Encoding.
So pdfwrite converts the character code into a (bogus) glyph name, and then tries to
look up that glyph name in the GlyphNames2Unicode dictionary. Obviously this fails.
I've extended the 'decode_glyph' call so that it takes both the glyph name and the
character code, for CID fonts the character code is always -1. If the glyph name can't
be found in the GlyphNames2Unicode dictionary then we try to use the character code
instead.
This works for this test case, and I don't think its likely to produce worse results
than the old code. Regression tests show no differences, but since they don't test
ToUnicode CMaps they weren't expected to. My own tests seem to be OK but I can't say
I'm terribly sure about this one.

This includes our tiny tweak to be able to get the input/output formats for

mechanism to redirect malloc/free etc through us rather than hacking the
code direct. Thanks to Marti Maria for both of these.

Fix (ps2write/pdfwrite) : bitmapped font problem
When producing an inline image representing a glyph which could not be embedded as text,
the code emitted the matrix setup for the image before opening the context. If there
was (for example) a pending text operation this caused the matrix setup to appear in
the text context instead of the image context, leading to the image disappearing.
Opening the image context before emitting the matrix solves the problem.

Fixes 691870 where the banding code was using an ICC color and the
full page was not. For color spaces in images we never actually call
"setcolorspace" so the image type was not being set to icc, we do this
now explicitly in the PCL/XL code now.

Initial import of LittleCMS v2.1 into the Ghostscript/GhostPDL
build, with simple integration. LittleCMS version 1 is still used by default,
so no cluster differences expected.
The version of little cms imported was taken from the lcms git repository,
commit 314bc7201d340ab303b36a0ade2c37cf40b83a3b, and then a couple of
small tweaks were applied:
* lcms2 currently offers no way to get the input/output format for a
transform, so I add 2 functions (cmsGetTransformInputFormat and
cmsGetTransformOutputFormat) to do this.
* lcms2 currently offers no easy way to redirect malloc/free operations
away from it's internal implementation, so we add a define (LCMS_USER_ALLOC)
to allow us to be able to define our own functions. This mirrors the
work done in lcms1 by Michael, I believe.
The choice of which version of lcms to build with is made by the WHICH_CMS
define option in the makefile. Currently this is set to lcms by default,
but can be changed to lcms2 to allow lcms2 to be used instead.
To make this work, various small tweaks have been required. Firstly, we
rename gsicc_littlecms.h to gsicc_cms.h, reflecting the fact that this is
not littlecms specific - rather, it defines the interface that any cms
would have to provide in order to work with Ghostscript/GhostPDL.
Secondly, we rename gsicc_littlecms.c to gsicc_lcms.c to make the makefile
macros easier.
We add a gsicc_lcms2.c file (derived from copying and editing gsicc_lcms.c)
that interfaces with lcms2.
Currently lcms2 builds and appears to run without crashing, but gives
differing results in some cases. This will need to be solved before we can
swap over to using lcms2 by default.

Fix so that anti-aliasing works when the source file contains transparency. This involved the addition of a copy_alpha procedure for the gdevp14 device. In addition, the anti-aliasing parameters for the target device are passed along to the gdevp14 device. The gdevp14 clist device uses the forward copy alpha operation, so that we end up using the clist_copy_alpha operation. Then during the clist reading phase we use the gdevp14 device's copy_alpha command.
There are two things that I do need to do in relation to this commit. One is that the operation that actually computes and applies the alpha associated with the transparency needs to be optimized so that we are not doing floating point math. Also, support needs to be added for knockout fills. However, for the vast majority of files with transparency we should now have support with -dGraphicAlphaBits and -dTextAlphaBits.
I will open a bug on the two outstanding issues so that I don't forget.

Bug #692100, padding was being treated inconsistently within 2

xps: Fix bug when parsing cluster mappings.
We incorrectly encoded and emitted all characters in a
Many-to-One cluster mapping, resulting in extraneous characters
where ligatures were used. A (2:1) cluster map for the ligature
"fi" has two characters (f, i) and one glyph (fi). We showed it
as two glyphs (fi, i) instead of skipping the second character
while decoding the cluster map.

extra int to identify which plane we want to work on.
The call effectively says "Copy this pixmap into the specified plane of this

For now clients can detect whether or not to use this based on whether the
function pointer is non NULL. If need be (to cope with forwarding devices)
we can add a dev_spec_op.

the 'standard' 1bit cmyk way, and use that rather than manually checking

## Version 9.02 (2011-03-30)

This is the third release in the stable 9.x series.

This is an "out of order" release, primarily to ensure the GPL Ghostscript release remains in version "lock-step" with the Artifex commercial release.

Highlights in this release include:

For monochrome devices, there is a new halftone technique for sampled image data. The existing technique is very efficient (and is is still used) for large areas of color, such as an area fill, but encountered performance problems dealing with sampled image data where a given colour value only covered a few pixels at a time. The new approach applies the halftone threshold array directly to the image samples.

Further performance, memory use, and stability improvements with the new features introduced in 9.00, as well as Unix/Linux build fixes, plus the usual assorted bug fixes.

For a list of open issues, or to report problems, please visit bugs.ghostscript.com.

Resolve build issues with language_switch and UFST. I had (wrongly) assumed that the PCL/language_switch builds with UFST and COMPILE_INITS=1 would have the relevant paths correctly setup for the PS/PDF world to access the Microtype FCOs. It turns out they are done in an incompatible manner. So, I've renamed the path variables (in the makefiles) so there isn't a clash between PCL and PS/PDF, ensured that the variables are correctly passed through recursive (n)make calls, and tidied up the FAPI options for the language_switch build. Not only does this allow language_switch to build with the UFST, but the Postscript interpreter does now use FAPI/UFST to access the Microtype fonts for the built-in fonts, and uses FAPI/Freetype for downloaded fonts.

A temp fix for bugs 692038 and 692065. The clist devices that are created for the threads now inherit the icc profile from the target device. I need to set things up so that the device profile is no longer reference counted since we could have a race condition problem if the different threads are incrementing and decrementing the count and if the command is not atomic on a particular architecture. The plan will be to no longer ref count the device profile but to have it maintained until the the actual target device is destroyed. There will be a bit of work to do with respect to the pdf14 device, which can have a device profile that is different than the actual target device. That profile can be altered with the transparency group pushes and pops.

Fix (ps2write) : Indexed colour images have incorrect /Decode Bug #691924 "Differences in colour with ps2write" The problem was due to the opdfread code generating a /Decode for an Indexed colour space where the value was [0 2^n] and should be [0 ((2^n) - 1)]. This caused the highest image sample to be mapped to 1 past the end of the samples in the colour space. Normally this doesn't matter, because the values are clamped to 'hival' in the Indexed space. In this case, however, the image was 2 bpp (4 values) but the colour space was defined as a full 256 indices, with only the first 4 bein used. The incorrect Decode caused the image sample value 3 to be looked up as colour space sample 4, which was set to all 0 (black) causing incorrect colour values.

Fix (ps2write) : Don't set a default halftone. Bug #691923 "Differences in dithered output with ps2write" The PDF interpreter emits a setpagdevice between every page of output, in case the media size has changed. The implementation of setpagedevice resets the halftone to be the default halftone (106 lpi 45 degree line screen). This is a problem for ps2write, and potantially pdfwrite, as there is no way to differentiate between a default halftone set by setpagdevice, and a halftone contained in the input file. To avoid embedding an unhelpful halftone, we now check the device parameter '/HighLevelDevice' in the setpagedevice implementation, and if it is present and true, we do not call .setdefaulthalftone. Also updates documentation on device parameters. This causes differences on every 1-bit rendering test (ie pkmraw) of the ps2write output file, so approximately 1300 differences are to be expected.

Fix Bug 692064. Tiffscaled device was checking on page print time that the expected size of the page wouldn't make the page too large to fit in a file. This code was copied from the tiffgray device (as we render internally in 8bpp). As we output in monochrome however (and may use compression) the test is in fact bogus, and should simply be removed. We do that here. It's entirely possible that we should be removing the test from the tiffgray device too - most systems with 32bit longs support large files these days, and compression may apply here too anyway. I'll leave this until it becomes an issue though. No cluster differences expected.

Some updates to the new device parameters. It turned out that the intended parameter Type32ToUnicode was incorrectly implemented. This should actually have used the WantsToUnicode parameter, because the code actually controls the processing of GlyphNames2Unicode tables from Windows PostScript. This means we no longer need the Type32ToUnicode parameter and it has been removed. Added initial documentation of these parameters. This appears to cause some differences in Bug690829.ps rendered at 300 dpi. This is a surprise, because the changes should have no effect on devices other than pdfwrite/ps2write, but the new result is better than the old, so this is a progression.

Some (broken) TrueType fonts have out of order loca tables, which can result in the calculated glyph data lengths being larger than the actual available glyph data. Normally this does not cause a problem, but if the glyph in question is in the final bytes of the stream, we encounter an unexpected end of data condition when creating the glyph data buffer to pass into Freetype. So the FAPI interface code will now ignore that error, and adjust the byte length to correctly reflect the number of bytes available in the buffer. It is safe to do this because, in the event we have a genuine out-of-data condition, Freetype will return an error when it tries to interpret the glyph outline. Bug 692043 No cluster differences expected.

Planar device is broken w.r.t rops in a cmyk space - this commit fixes it. The planar memory device sets itself to use gx_default_strip_copy_rop rather than mem_strip_copy_rop. mem_strip_copy_rop knows that rops on cmyk pixels should actually convert to rgb, perform the rop, and convert back again, but doesn't know how to convert the results back when it's in planar mode. gs_default_strip_copy_rop can cope with planar mode, but doesn't know to convert to rgb first. The first fix included here is to extend mem_strip_copy_rop to know how to write back to planar format, and then to make the planar memory device use mem_strip_copy_rop. This then exposes various flaws in mem_strip_copy_rop, including the fact that it relies on being able to set the offset in get_bits calls when this is sometimes not possible. We therefore fix the code to manage offsets by explicitly updating them. Also, the raster used in mem_strip_copy_rop was incorrect - we use the correct one and get much better results. No cluster differences expected as the planar device is not tested.

Remove the buffer blanking done in gximono.c. Previously removing this would have caused indeterminisms. With the additional fix in here to limit offset_bits to dest_width, however, we should get stable results. This gives various differences in output (81 in pcl, presumably more in PDF and PS). Bmpcmp of the pcl ones shows them as all progressions.

Update the remaining PostScript files (mostly the PDF interpreter) to use the new device parameters instead of explicitly checking for the device being named 'pdfwrite' or 'ps2write'. Some more modification is still required, but we're nearly there. We will continue to check the device names in gs_pdfwr.ps when setting up the default state for those specific devices. Although not strictly a Distiller device, ps2write declares itself to be 'IsDistiller'. This is because some PostScript test files were found to behave differently if the distillerparams operators were available, in particular files would be oriented differently if the device was deemed to be a Distiller.

Fix for bug 692038. This fixes 3 issues when using a CIELAB based profile for the output device ICC profile. One was a problem when handling separation color spaces when they had the ALL entry and we were going to an additive device. AR does a 1-INK level for the device values and no color management. We were doing the same, but this approach will not work if our destination color space is CIELAB. Now if we are headed toward CIELAB we do the 1-INK to RGB and then transform to CIELAB. Another was that transparency blending should never be done in CIELAB or similar type color spaces. With transparency, the PDF14 device inherits the profile for the target device and if the transparency groups don't specify a color space we would end up blending in CIELAB. The solution was to detect this situation and use the defaultRGB profile for blending. Conversion to CIELAB occurs during the pdf14 put image operation. Finally, with shading in transparency, we need to make sure to pass along the transparency device through the shading parameters whenever we have a color mismatch between the pdf14 device and the target device so that the shading will occur in the proper color space. These changes are all related to a non-tested cluster case when we have -sOutputICCProfile=lab.icc

Disable PACIFY_VALGRIND in gximono.c. This define is intended to enable extra code that can be performed so as to ensure that valgrind doesn't report false positives. As such, disabling it should have no adverse effects. Unfortunately, it seems that in the portrait case, if we don't blank the threshold array before we run, we get diffs. I have therefore taken this memset out of the PACIFY_VALGRIND case and forced it to always happen. This probably points to a bug and should be investigated properly. No cluster differences expected.

Change to gsroprun1.h to avoid over/underreading the source/texture buffers. Given a valid byte range we expand that to the smallest enclosing CHUNK range and guarantee never to access out of that range. Previously we could read one CHUNK before/after it. If this is a problem, simply ensure that CHUNK is byte rather than int on your platform. This now behaves better than the original code which would access one byte before/after the defined range.

Fix for compositor device chaining in the pdf14 device. This was detected in a file that did overprint along with transparency. The pdf14 device incremented the ref_count for the overprint_device, but never decremented it since the 'finalize' of the pdf14 device was left at NULL rather than being set to the gx_forward_finalize function which should be used. The gx_device_set_target, rather than rc_assign does the proper set of the finalize proc pointer so that reference counts for the device chain are properly maintained. Detected by customer 532 since their device freed the clist buf_device resulting in the overprint_device having a 'target' pointer to freed memory, causing a SEGV when the 'finalize' function executed. No regressions expected since in the normal code, the GC frees the devices that were left unreferenced by the free of the pdf14 device.

The get_bits() device call was assumed to return copied data and fill in the allocated memory pointed to by the variable row, in fact the gets_bit call can also just return a pointer and row is never initialized, now we detect that.

I stepped through them in a bmpcmp to check for serious issues. The minor halftone differences were due to the fact that we step in the device space for pixel replication in the threshold code but step in source space for the rect fill code.

Fix rop operation on plib device. Previously, I'd disabled get_bits_rectangle on the buffer device as the data is normally in the format we need it in anyway, so it's a NOP. Unfortunately it's needed for rop operation, so reintroduce it. To avoid infinite loops, we have to cope with GB_RETURN_POINTER. This is easy to add to the gdevmpla.c device, but it's less clear that adding it into the mem device is the right thing to do. We therefore introduce a shim function to cope with GB_RETURN_POINTER with the mem device. No cluster differences expected as this is disabled by default. Testing shows that the planar device is now very close to the non planar equivalent.

Introduction of a member variable in gs_image1_t, which will let us know the original source type of the image. For example if, the parent source were type3 this spawns two type1 images. One for the mask and one for the image data. The mask is rendered using image render simple. If the image is monochrome or indexed, it is rendered with the renderer in gximono.c . If we are going to a halftone monochrome device, we end up using the fast threshold based renderer which has its interpolation stepping in device space as opposed to source space. This causes very minor differences between the mask and the image data. To avoid this, we use the old rect_fill code for the image type3 data to ensure a more exact spatial match.

Added color management support to the CUPS ...toraster filters Replaced the ...toraster filters by one filter executable, gstoraster, written in C. This filter converts both PostScript and PDF input into the CUPS Raster format using Ghostscript with the "cups" output device, controlled by settings in the print queue's PPD file, by command line options, and by settings embedded in a PostScript input stream. This is now done with color management based on printer-specific ICC profiles referenced in the PPD file or supplied by the color management daemon colord. The CUPS PPD extensions concerning color management (http://www.cups.org/documentation.php/doc-1.4/spec-ppd.html) are made use of if used and the colord daemon is used if it is present. colord is accessed via D-Bus, but the new filter can also be compiled without D-Bus and in this case only the CUPS PPD extensions and ICC profiles assigned to the print queue are used for color management. Thanks to Richard Hughes for the patch.

Fix bug reported by "new customer feb 2011", whereby gs 8.71 on an embedded ppc platform is getting the colours on an image in a pdf wrong. Debugging shows that in gs_indexed_limit_and_lookup we take a floating point value, clip it, convert it to an int and use it to lookup which colour to use. On the reference x86 run we have a value of 1 (0x3f800000 as an IEEE float). On the ppc we have 0.999999 (0x3f7fffff as an IEEE float). This tiny difference results in values of 1 and 0 respectively when converted to the int, giving the wrong colour. The fix here is to add a small epsilon before conversion. A quick experiment in adding 0.5 rather than epsilon shows worse results. 15 cluster differences in testing, none that actually survived a bmpcmp.

Addition of code to incorporate the inverse of the transfer curve into the threshold matrix. If the curve is an inverting type (e.g. 0 to 1 and 1 to 0) then a the thresholding comparison is switched. Also, if the curve is not monotonic, it can not be inverted and we revert to the old rect fill method. This commit has the code disabled so there should not be any regressions.

Add new plib family of devices (PLanar Interlaced Buffer). These 5 devices (plib = r8g8b8, plibg = g8, plibm = mono, plibc = c8m8y8k8, plibk = c1m1y1k1) use a new 'band donor' interface to request a band buffer, pass back rendered bands, and release bands at the end of the page. The idea is that other firmware can implement this simple interface, and Ghostscript can thus easily drive systems that expect planar interlaced input. On the whole there is relatively little new code here; the majority of the work is done using the existing planar device with the odd tweak here and there. Firstly, we lift the (artifical) constraints of the number of components supported (so greyscale is accepted as a planar device for simplicity). We spot the num_components = 1 case and just use the existing memory device interface. Secondly, we add a fast 888chunky to 888planar unpacking routine for use with copy_color. Within the plib device itself, we make use of the facility to set the line indexes to allow for interlaced operation. It would be easy to extend this device to offer planar non-interlaced operation too built on the same band donor interface simply by omitting this code. For debugging purposes we have options within the plib devices to store the data returned in each band into pxm files (as appropriate to the number of components). This code is deactivated by default as the output of this device is via the band donor interface, not the output file. No cluster differences expected as this code is disabled currently. Next job: discuss with Marcos how to cluster test this.

Recommit of 12163 to the trunk. The fit_copy macro checks for the start address being off the top of the screen, and clips it to zero. When it does this, it does: data -= y * raster, which gives problems if raster is a uint ( as uint * int == uint in C) and data is a 64 bit pointer. The fix is simply to cast the result to an int before using it. This solves various SEGVs with the mono_copy_mono using mono_copy_rop code. No cluster differences expected.

Initial reorganisation of code towards using copy_rops for copy_mono. Split the guts of mem_mono_strip_copy_rop out into a separate function mem_mem_strip_copy_rop_dev. This new function handles the actual copy in device space, leaving the original to cope with fiddling the rop according to colors. This 'inner' function is moved to gdevm1.c so it is present in both gs and ghostpcl builds. The existing (bitrotted) code in gdevm1.c to 'USE_COPY_ROP' is revamped to call mem_strip_copy_rop_dev, but is disabled currently as the cluster is showing a few differences that need to be tracked down. Also, this introduces new code to do gsroprun's using code in a generic header file that gets repeatedly #included with different options. This code is currently disabled until we can verify that it gives identical results. The new 'templated' code uses native ints where possible, and (in initial limited testing) seems to perform better than copy_mono. No cluster differences expected.

Enhancement (pdfwrite) : performance improvement Bug #691946 "Conversion to PDF becomes slower and slower" There are many places where pdfwrite compares composite objects for equality. This can be a very slow process, depending on the nature of the object, and becomes progressively slower as more object are added to storage. Previously we had added a MD5 hash to the stream data of a cos_stream in order to improve the performance when checking fonts for equality, this change takes the whole process much further. We now store an MD5 'fingerprint' for each composite object, initially this is not computed and is marked as not valid. Whenever an equality test takes place we check to see if the composite object has an MD5 hash calculated, and if it does, we compare the MD5 hashes. If it does not then we compute an MD5 hash, store it, and mark it as valid. Note that for cos_stream types we store *two* hashes, one for the dictionary and one for the stream data. If we alter the contents of a composite object then we mark its MD5 hash as invalid so that we recompute it on the next occurence. Technically there could be a problem if a composite object contains a composite object, and the descendant object is altered after the MD5 hash is calculated for the parent. However this should not occur given the way these structures are used (these are pdfwrite internal structures, *not* PS or PDF objects available to the interpreter). This very significantly improves performance on some files, the test file for bug #691946 takes 2642 seconds without this change (and DetectDuplicateImages true) while it takes 963 seconds after this change. Note that this change depends on revision 12169 and should ideally be used with revisions 12168 to 12171 inclusive. No other differences expected.

Fix (pdfwrite) : images being scaled incorrectly Found while dealing with other problems. pdfwrite uses the image 'height' (rendered height) and number of lines of data to calculate a 'scale' which it then applies to the current Transformation Matrix in order to calculate an image matrix. However, when an image was detected as a duplicate, the scale factor was calculated from the first image's dimensions, and then applied to the CTM for the second matrix. This did not appear to cause problems for PostScript and PDF but causes serious bugs in a number of PCL files, and was clearly incorrect. We now save and restore the height and width when substituting images to prevent this problem

enhancement (pdfwrite) : Allow duplication image detection to be disabled pdfwrite tests every (non-inline) image against every other stored image to see if it is a duplicate, and if so does not embed the duplicate in the output but simply references the original.

Fix (pdfwrite) : Correction to an equality test This fixes a long-standing bug when checking the equality of patterns. We need to ensure when substituting patterns that neither of the patterns is already substituted. But the code only tested one of the patterns (and was a duplicate of another test), which led to incorrect results. This should always have been a problem but for some reason seems to have been masked in previous releases. New code for testing equality of composite objects revealed the problem. No differences expected, as the problem is only revealed with code which follows in a subsequent commit.

Fix : colour space handling bug and improved handling of broken ICC space Bug #691941 "Interpretation of PDF aborts with /typecheck" The PDF file in the specimen contains an invalid colour space of the form: /Indexed [/ICCBased <</N 1 /Alternate [/Indexed /DeviceRGB 255 7 0 R]>>] 255 7 0 R] The number of components in the ICCBased specification is incorrect, as the profile has 3 channels. This was not detected previously. Falling back to the /Alternate we see that we have a /Indexed space depending on a /Indexed space which is also invalid, but we choose to ignore this. There was also a bug in the colour space handling for ICCbased spaces which caused a typecheck if the alternate space was a /Indexed space. Finally, the PDF interpreter is updated so that when given a stream as the data source for a /Indexed space it reads and returns a string which is the greater of the declared size of the stream, or the calculated size required, given the number of components. Previously we always returned the calculated size, which was too little in this case as the number of components in the ICCBased space is incorrect. With these changes the (invalid) specimen file runs to completion. No differences expected.

## Version 9.01 (2011-02-07)

This is the second release in the stable 9.x series.

Highlights in this release include:

A new, robust CFF parser implemented in C (replacing the previous Poscript one),

tiffscaled device - this renders internally as tiffgray, but then downsamples by an integer scale factor (specified by -dDownScaleFactor=n) and error diffuses to 1bpp output. The tiffscaled device also implements limited minimum feature size functionality; by setting -dMinFeatureSize to 1, 2 or 3, the device output is guaranteed to generate minimum dot sizes as multiples of the final resolution, useful for devices that offer finer position control than dot size control.

Add DSC compatible output in ps2write.

Windows makefiles now support 64 bit builds on 64 bit systems.

A number of performance, memory use, and stability improvements with the new features introduced in 9.00, plus the usual bug fixes.

We have also dropped support for Watcom and Borland development environments. These had not been maintained for some time, and were suffering "bit rot".

Change Windows makefiles extensively for 64-bit issues: 1. Command line nmake works now for 32-bit build on 64-bit OS 2. 64-bit builds use different directories for objects to allow 32 and 64 bit builds to be alternated without confusion. 64-bit objects have '64' suffix to the 32-bit objects which remain in the same places 3. 64-bit binaries are now named uniquely, e.g. gsdll64.dll and gswin64.exe Binaries coexist in 'bin' directory since names are unique. 4. 'Style' changes to the makefiles to remove the '32' suffix from files that are not 32-bit specific -- hopefully will prevent future confusion.

A set of changes to make it easier to use the UFST with Ghostscript and to get us closer to having the option of the UFST handling font types other than the Microtype fonts. The UFST build, using the default COMPILE_INITS=1 will now include the Microtype FCO files in the rom file system along with the other initialisation files (it does not currently strip out the normal Postscript fonts in Resource/Fonts), and setup default values for the various paramters required to have Ghostscript use the Microtype fonts (these can still be overridden on the command line). For the build with COMPILE_INITS=0, the default paths will use the path to the UFST you specify for configure, or nmake on Windows. Included in this revision are changes to prevent the UFST version 5.x (or less) from trying to handle non-Microtype fonts, and allow it to safely fall back to the Freetype (or a.n.other FAPI plugin). UFST 6.2 or better will try to handle all fonts types, but this is not yet reliable. Currently, this code only replaces the UFST memory management on UFST 6.2 and above (this is purely because I haven't time to test this capability on UFST 5 yet). A further change will be committed shortly to the UFST 5 sources to force the UFST to use the Ghostscript stream IO instead of the standard lib file IO on the Windows builds (this has been in place for the Unix/Linux UFST builds for some time).

Fix ps2write : Don't depend on the PS file system for resources. ps2write needs up to 4 resource files which are normally stored in the PostScript ROM file system. However on PCL and other languages these resources are (obviously) not present, so the output is incomplete. Move the relevant files from PostScript into 'C' as header files. Remove the files from the PostScript file system to save ROM file system space. Put the removed files into the gs/lib folder for safe-keeping. Add the .h files as dependencies for gdevpdfu.c in the build system so that changes to these files cause a rebuild. No differences expected.

Fix (pdfwrite) : Always write a ToUnicode CMap for TrueType fonts Bug #691907 "PDFs with TrueType fonts from Windows PostScript files not searchable" Patch from SaGS. When choosing whether to embed a ToUnicode CMap, always embed if the font type is TrueType. This is because TT fonts are always embedded as symbolic, and we now no longer add Encodings to Symbolic TT fonts (violates spec), which results in PDF files where the text is unsearchable and cannot be successfully copy/pasted in the absence of a ToUnicode CMap. It is possible that the ToUnicode CMap is incorrectly generated, but this is no worse than having no CMap at all. No expected differences since ToUnicode CMaps are not used in rendering.

Add new 'Profile' configuration to Visual Studio targets. This builds objects/binaries with debugging symbols enabled, but otherwise full optimisation. The changes are entirely within the VS files, except for a few small tweaks to the MSVC makefile. These changes should mean that it is possible to use the makefiles in a way that doesn't rely on recursive make calls (even though we leave the 'debug' targets in for now that do use that). No cluster differences expected or shown in testing.

Fix (pdfwrite) : permit symbolic fonts in PDF/A output Bug #691877 "Invalid text when converting to PDF/A" TrueType fonts were being emitted as non-symbolic when PDF/A output was selected. This was causing the text to be incorrect, because the fonts actually are symbolic and Acrobat was unable to apply the correct decoding. This will result in more text being unsearchable/copyable but the rendering result is correct, which is more important. No differences expected, PDF/A output not tested on the cluster.

While searching for performance on an ARM based dev board, I developed 2 new versions of the skip_white_pixels macro. The first uses native int sized checking, and should be faster on long run matching. I have as yet been unable to find any files that show this expected speedup. The second should be faster on architectures (such as ARM) where the tradeoff in the test is different (and where pointer arithmetic is cheaper than array indexing). Both versions are disabled by default until the case for their existence has been proven, but are committed here to avoid bitrot. No cluster differences expected, as the default code does not change.

More changes for CUPS, mostly to the build system. We now build the CUPS device unconditionally on Windows, using the recently added local partial copy of the CUPS library sources. This change also builds CUPS on Linux either using the system shared libraries (if available) or using the same partial copy of the library sources, if *specifically* directed to use this. On Windows CUPS is now always built and installed. On Unix systems the behavious is as follows: ./configure cups not installed - no cups device ./configure cups is installed - cups device linked to system cups shared libraries. ./configure --disable-cups - no cups device, regardless of cups libs installed on system ./configure --with-local-cups - cups device with the partial cups code, regardless of cups libs installed on system ./configure --with-local-cups --disable-cups results in no cups device. No differences expected as the cluster should still build and run with the system CUPS libraries just as it always has.

More changes to the CUPS sources so they will compile on various systems: language.c - if __APPLE__ is true, includes code which uses what I think is Carbon Framework calls and structures, but does not #include any of the .h files. Modified to #undef __APPLE__ to avoid this. ppd.c - Same problem as for MSVC, the include file string.h seems to prevent the C string.h being included, and so leaves strchr undefined. Now unconditionally provide a prototype for strchr. localize.c - Another problem with string.h. This doesn't exist on the MSVC build, but unconditionally providing a prototype fro strcmp doesn't cause an error. The code now builds on MSVC, Linux and Mac. Lots of warnings, but I don't propose to try and deal with those as they would require extensive alterations to the CUPS sources. No differences expected as this code is not yet in use.

Optimisations to mem_mapped8_copy_mono. Driven initially by a desire to speed up 100pagemono.pxl on ARM devices, but useful on all architectures. This work may end up being subsumed by the run_rop work, but is a worthwhile stepping stone. On x86 this speeds 100pagemono.pxl in greyscale 600dpi from 4.2 seconds to 3.6seconds. On ARM it shows a definite improvement too, but I don't have figures to hand. Clusterpush shows no changes.

Update the CUPS sources so that they can be compiled under Windows. 1) Remove config.h which was a Linux configure result, replace with configwin.h (from the CUPS distribution for Windows) and configlinux.h which is config,h renamed. We will copy and use the correct version at make time. 2) cups/debug.c guard the use of pthread_mutex so that we don't try to use it if HAVE_PTHREAD_H is not defined, as the variable will not be declared. Guard use of cups_debug_filter and cups_filter with a #ifndef WIN32 as these variables are not defined in a Windows build. Replace gettimeofday with a Windows equivalent when building on Windows as this function is not available. 3) ppd.c Add a definition of strchr when building for Windows. The use of an include file called string.h confuses MSVC and it does not include the C string.h which leaves strchr undefined. 4) string.h When defining equivalents to strcasecmp and strncasecmp, also define the HAVE_* variables so that inclusion order doesn't lead to these being undefined when we have declared equivalents. 5) image-bmp.c Guard the declaration of the BI_* constants with a #ifndef WIN32 as these are Windows constants and already defined on a Windows build. 6) image-colorspace.c Define cbrt() in terms of pow() when WIN32 is set as the MSVC compiler does not define a cube root function. 7) image-tiff.c Guard inclusion of unistd.h when HAVE_LIBTIFF is true as this include file does not ship with MSVC on Windows. These have been supplied to the CUPS development group, and at least some of the problems are likely resolved in a newer version of CUPS. No differences expected.

We want to be able to use planar buffers in a line interleaved format. Unfortunately, at the moment the planar device is hardcoded to use contiguous buffers. Fortunately this appears to be a 1 line fix; rather than calculting raster from the width, we instead calculate it as the difference between line pointers. This does assume that we can always safely read line_ptrs[1], even if we only have 1 line in the band. (The value is unimportant in this case, but we must be able to read it without crashing.)

Also, fix up the the non shared library builds, so they will still work with --enable-dynamic (only really useful for debugging). Bug 691905. Reorganise and correct the names of the devices specified in configure.ac so that the options --with-drivers=[FILES,PRINTERS,X11] actually work.

Revision 12038 revealed a bug in the transparency code; an operation with a blend mode of 'Normal' and a solid alpha would be allowed to use the fast stroking code, even though it had transparency in due to being a pattern. Here we fix the code to check for transparency. As noted on bug 691900 this test treats all type 2 patterns as being transparent, so could be improved. The cluster differences this gives have been checked and correct the regressions of revision 12038.

Bug 691897 shows a PDF that is much slower when transparency is enabled than when it is not. The time is primarily spent in the stroke filling code due to the fact that when transparency is enabled strokes need to be rendered all at once, rather than segment by segment. This causes the scan conversion code to have to work much harder. In fact, the code uses solid alpha and "compatible" blend mode for most strokes, so we would be perfectly safe to use the normal mechanism. The code attempts to recognise this case already, but was only spotting "Normal" blend mode and not it's synonym "Compatible". We now roll the two together. Cluster testing shows this produces various differences; none to do with blending, all to do with different roundings in the positions of the stroked paths. Bug 690845 is open for this already.

Changes to the Unix configure based builds to tidy up specifying subsets of output devices. Some devices were always being included regardless of the options given to configure, resolved by tidying up the macro expansions in Makefile.in done by the configure script. Also the page device and clist device are effectively required by all configurations, so those are now included in the core build. Finally, the contrib/gomni.c driver relied on two functions in base/gdevbmpc.c which is an optional driver, so configuring the Omni driver to be built it, and bmp16 not would result in undefined symbols. contrib/gomni.c now has its own equivalents of those functions.

The source of this was that the cups and psdcmyk device are now using the older slower color image rendering function due to the fact that they have non-standard color mapping procedures.

This was causing a check for color range mask testing even when the image was not a type 4.

Added the source code of the CUPS libraries to the Ghostscript source package Like with zlib, libpng, libjpeg, ... it is now possible to build the complete Ghostscript (including the CUPS Raster output device) on systems where there is no CUPS library available. Note that currently only the CUPS library source code is added, the results of the ./configure run in the Makedefs and config.h files, and the Makefiles are stripped to only build the libraries and nothing else. The CUPS ./configure command line which was used to obtain makedefs and config.h was ./configure --enable-static --without-shared --disable-dbus --without-php \ --disable-slp --disable-gssapi --disable-ldap --disable-ssl \ --disable-cdsassl --disable-gnutls --disable-openssl --disable-pam \ --disable-dnssd --disable-launchd This way the built CUPS libraries do not need any system services or hardware interfaces of Linux. In addition to standard libraries they use only libz, libpng, libjpeg, and libtiff. These libraries Ghostscript needs anyway and copies of their source code also ship with Ghostscript.

Fix so that we do not do the ICC optimized flow for color images when our target device does not have standard color mapping procedures. This occurs for example, in the case for the CUPs device where the color mapping procedures map CMYK, RGB and Gray to the current CUPs device color space. For standard gray, RGB and CMYK devices these procedures are avoided as the CMM performs all the required mappings. This commit will show differences in the files for the cups device as well as the psdcmyk device, which also should be using the non-optimized flow due to the use of CMYK + spot colorants, which will not be managed correctly by the CMM in general. The differences int the psdcmyk files that do not have extra spot colorants are tiny. This should fix bug 691760.

Use the "x11" output device as default output device for an X-enabled Ghostscript, as "x11alpha" is too buggy The simple call "gs <file>" is a common call to check a PostScript file when debugging printing problems. Unfortunately, this call uses the "x11alpha" output device which has a lot of bugs, especially on complex input files. This makes easily a wrong impression of the input file then. Having a somewhat inferior screen output quality (no anti-aliasing) is no problem as the mentioned Ghostscript call is only used for debugging purposes.

ps2write DSC enhancement. Belt and braces approach when emitting a serialised array/proc This code should break an (already serialised) array or procedure emission if the total length of the data to write exceeds 255 bytes. The data will be broken at name, array, string or procedure tokens (ie '/', '[', '(', '<') or a space character. If none of these occurs in the preceding 255 bytes then we emit a line break anyway and carry on. I do not have any test cases which exercise this code path with a data size > 255 bytes, so I'm not certain that it works as expected. No differences expected as the regression test doesn't exercise ps2write.

Fix so that the presence of source black and white are properly detected with the ICC color management changes. This detection is useful for the optimization of certain ROPs. Previously black and white were detected from looking at the device color. This was a problem since the device black color is usually not pure for a CMYK printer with the ICC changes. This fix updates the detection function so that it looks at the source color and maps it to the default RGB color space where black and white are well defined.

Fix (pdfwrite) : Write ToUnicode CMap files which Acrobat likes Bug #691862 (and also bug #691849) "Unable to copy text from the converted PDF" It seems the Adobe documentation lies (or more generously is inconsistent). The CMap tech note (5014) says that entries are not zero padded, so values less than 256 are emitted as single bytes, values 256->65535 are two bytes etc. However the ToUnicode CMap tech note (5411) says: "Because a “ToUnicode” mapping file is used to covert from CIDs (which begin at decimal 0, which is expressed as 0x0000 in hexadecimal notation) to Unicode code points, the following “codespacerange” definition, without exception, shall always be used: 1 begincodespacerange <0000> <FFFF>endcodespacerange" (This is somewhat restrictive, since CIDs can exceed 2 bytes, even though UTF-16 can't, I could forsee a need to map high CIDs to lower UTF-16 values) Finally, the PDF Reference (1.7) says: "The CMap file must contain begincodespacerange and endcodespacerangeoperators that are consistent with the encoding that the font uses. In particular, for a simple font, the codespace must be one byte long." So the PDF Reference conflicts with the tech note which it references! In fact none of the above seems to be quite what Acrobat actually does. It seems that Acrobat does not care what size (in bytes) the codespacerange is, no matter what kind of font is present. However it *does* care what size the bfrange entries are. For simple fonts the bfrange entries must be single bytes, for CIDFonts the bfrange entries must be two bytes. Deviation in either case leads to files which Acrobat cannot process and either causes errors or incorrect text when copying and pasting. Changed the ToUnicode emission (mostly restoring revision 11170 which was removed in revision 11795 because of bug #691849) so that we emit single byte bfrange and codespacerange arguments for simple (non-CID) fonts, and emit double byte, padded with 00 arguments to bfrange and codespacerange for CID fonts. No differences expected as this only affects text search/copy in Acrobat.

The optimization in gdevdgbr to detect a device with a "plain" cmyk 1 bit to rgb mapping was broken because the procedure cmyk_1bit_map_color_rgb() is obsolete. The hack here is to detect output formats compatible with gx_get_bits_copy_cmyk_1bit() which is significantly faster since it does not have to call the device color decode procedure. The device API should have a member that indicates the most frequently encountered pixel organizations.

Fix ps2write : Attach Encoding for symbolic TrueType fonts The recent change to not attach Encodings to Sy,bolic TrueType fonts, as per the PDF spec, meant that ps2write also wrote symbolic TT fonts without a /Encoding. This is not ideal, because opdfread.ps then attaches a default StandardEncoding to the font. This simply will not work correctly. After some experimentation with extracting (in PostScript) the POST table from the TT font, sense prevailed. This patch modifies the condition so that if we are producing output for ps2write we continue to attach a /Encoding. (in this case it doesn't matter whether we are producing DSC output, we always want the Encoding) No differences expected.

Initial commit of code for creating halftone screens. This code needs additional debugging, especially in the case of edge parameters. It will currently create threshold arrays based upon desired lpi, angle, quantization levels, and device resolution. The method is restricted to angles that are the arctangent of rational numbers. Every attempt is made to achieve the requested lpi by using the rational angle that achieves an lpi over the requested value. Since there is a trade off between lpi and quantization levels, the requested quantization levels are obtained through dithering of the dot cells within the supercell. Essentially, the dots within the supercell do not all take on the same values and can grow at different rates in a visually pleasing manner. There is still a bit of work to do still on this dithering as well as controlling the rate of growth for the dots.

This was required to prevent regression errors with the test suite when we altered the type 3 font accumulation so that it made more effort to preserve the input character code, in an attempt to improve searching. Revision 11969 fixes a problem with cached characters which was leading to the /Widths array containing garbage values.

Fix ps2write/pdfwrite : Up date the show enumerator with the cached character width When capturing a character bitmap on the first time it is rendered, pdfwrite and ps2write get the width of the glyph in the cache device. This is then used to update values in the show enumerator, and these values are used as the Widths entry for the glyph. When imaging an already cached character, however, the enumerator values are not updated which can lead to garbage (uninitialised data) being written as values in the /Widths array. This patch takes the value from the cached character 'wxy' and updates the show enumerator 'wxy' with it. This is then used as the value for the /Widths array.

The comment indicated this was to 'work-around' the limit in Acrobat of 32k on user co-ordinates, but this is too sever a clamp to apply, also the general case path code does not apply this limit. Altered to make the limit the 32k enforced by Acrobat.

pdfwrite enhancement : more DSC related activity Defer the output of the header and the opdfread.ps 'prcoset' until the output file is closed. This allows us to count the pages and emit the %%Pages: comment in the header instead of at the end of the file. Fix the PageBoundingBox comment to have two % characters instead of one. Check for a new flag 'DSC_OPDFREAD' at the start of opdfread.ps (and write its definition as part of the header emission in ps2write). If present this prevents the SetupPageView routine from using setmatrix to reset the CTM to the one saved during document setup. Because the DSC-compliant output puts save/restore around each page we don't need to reset the matrix, and the reset prevents the output from working properly with psnup. If the flag is not present, it is treated as false. The output now works with GSView, psselect and psnup. The only remaining work is to track the usage of ProcessDSC and see if we can reuse any of the comments parsed out of the input. No differences expected

pdfwrite enhancement : More work towards DSC compliance This is a resubmission of revision 11941, with some additional changes so that it doesn't crash with pdfwrite on Linux systems. We now pass around the 'type' of an object much more when writing. This is so that we can emit "%%BeginResource/%%EndResource" comment pairs around the resources we write. It is also required so that we *don't* write these comments around pages. The code now emits %%BeginProlog, then writes the opdfread.ps procedure. It then writes all the various resources used in the document, each with a reasonable DSC comment. Then it writes %%EndProlog. After this come the page descriptions, each is written with a %%Page: comment and a %%PageTrailer. Finally we write the %%Trailer, %%Pages comment (NB we write %%Pages: (atend) in the header comments as we don't know how many pages there will be until the end) and %%EOF. The resources are mostly defined as being of type 'file', as most of them are not normal PostScript resources. The DSC specification says under the %%BeginResource definition (file note on p72) "The enclosed segment is a fragment of PostScript language code or some other item that does not fall within the other resource categories" and so this seems the best type to use for our purposes. The output is now minimally DSC compliant, though there are a few other comments I'd like to add if possible. Given the way the file is created we are always going to have a large prolog, and that will need to be copied to all the pages if they are split individually, in order to make sure that all the required resources are present. Technically we could follow the resource chain and write %%IncludeResource comments, at the page level at least, but this is probably more effort than it is realistically worth. Still need to add some more DSC comment types, and run some extensive testing. No differences expected currently. Minimal testing with GSView suggests that the output so far is DSC-compliant as-is.

A change to how we get the advance width of the glyph from Freetype. Previously, we used the data in the glyph metrics structure, which are scaled, and the undid the scaling. This is correct method for everything except the horizontal and vertical advance distances. We now get the two advance distances from the glyph structure, and tell Freetype not to scale them, this avoids the rounding errors that occur due to Freetype's fixed point number format. It also saves the (less significant) error when we previously unscaled the value, and saves a couple of fairly large double precision calculations. This does cause a number of changes in the regression suite, the vast majority are pixel or so differences in glyph positions. A very few are improvements. Bugs 691778 and 691777

Fix (pdfwrite) : Hashing /Subrs didn't check all subrs. Bug #691815 "ps2pdf fails on attached ps file" The new code for hashing /Subrs, to improve font checking performance, stopped comparing /Subrs between two fonts as soon as either font had an error getting a specific /Subr. However it transpires that some fonts can have a null object for a /Subr (used to skip Subrs that do nothing), and this returns a typecheck error. This led to two fonts which differed only in the fact that one has (and uses) more Subrs than the other being perceived as identical. This could lead to pdfwrite using the wrong font when converting type 1 into CFF fonts and cause errors. The code now continues checking remainign /Subrs if a typecheck error occurs, and as an additional measure also checks the number of /Subrs in each font before deciding if they are compatible.

Fix (pdfwrite) : Work around Acrobat bug with /Encoding Bug #691809 "Regression: some PDF files produced by GhostPCL r11913 cannot be read by Acrobat 8.2.5" Acrobat 4 & 8 have a peculiar bug, if a type 3 font (may affect other font types, but it seems unlikely) has a WinAnsiEncoding, and no /Differences, then text set in that font is not displayed by these versions of Acrobat. This may be limited to glyphs which consist of a bitmap only. Forcing the emission of a /Differences array for each glyph used results in these versions of Acrobat displaying correctly (even though the 'differences' are in fact the standard Encodings). This does seem to be quite definitely an Acrobat bug which we are working around, no other PDF consumer seems to have a problem with these files.

Due to "lazy evaluation" of softmask groups, the graphics state can change between the creation of the softmask group form, and when it is executed. We'll now save the gstate and (most of) the ExtGState when the softmask group is defined, and then set both before evaluting the object. A few ExtGState entries are not easily set directly, so those are missing. This partially fixes Bug 691157, and fixes Bugs 690351, 691348 and 690535. It also resolves the remaining issue with 690535.

On return to the text processing, if the operation was a charpath, this would take precedence over closing the accumulator which would lead to significant later problems. Modified the code path to allow for the charproc accumulation to finish and if this is a charpath operation to rerun the operation using the newly captured glyph program. Note this can only occur if the first operation on a given glyph in a type 3 font is for a charpath.

Fix (pdfwrite) : pointers not marked for garbage collection Bug #691779 "SegFault with pdfwrite and more than one cid font" pdfwrite does lazy creation of Identity ToUnicode CMaps for inclusion in output PDF files (2 CMaps, one for horizontal and one for vertical writing). These pointers were not marked for the garabge collector, but were stored directly in the pdf device structure. The CMaps were assigned to a pdfont resource type, where the pointer to the CMap *was* marked for the garbage collector. This meant that if the pdfont resource was moved as a result of garbage collection, the CMap could be moved as well. This left a dangling pointer in the device structure. If another font resource required an identity CMap then the now garbage pointer from the device structure would be assigned. If the new font resource was moved as a result of garbage collection, then the attempt to relocate the CMap would fail and cause a crash. Fixed by marking the pointers in the device structure for the garbage collector. No differences expected.

Fix for bug 691785. The bitmap mask clip device has a long standing bug when attempting to clip a bitmap through a 1bpp bitmap (gxclipm.c, clip_runs_enumerate, line 283ish). The code detects runs of 'on' pixels in the mask. It then keeps the last run it found in a 1 place buffer (called 'previous'). This therefore represents the previous run found. Whenever we find a new run, we check to see if we can add it to the previous run to try to form a larger (vertical) rectangle. If we can't, we should write the previous rectangle out and remember the current one. Unfortunately the code was writing the current rectangle out, rather than the previous one. This has the effect of losing the first run on most lines out. 130 differences shown in cluster testing; confirmed in bmpcmp as progressions.

Fix so that we handle the \B command properly when we have transparency. The stroke should be drawn in a knock-out fashion rather than blended with the fill. This was achieved by adding in the push of a knockout transparency group for the stroke operation. The opacity for that group had to be 1 rather than what ever the current graphic state was (otherwise you end up with the opacity applied twice). That change revealed an issue in the clist when a transparency group is pushed where the opacity for the pdf14 clist device was being altered without having the information passed into the clist. Fixing that required a few changes to make sure that the blend parameter changes for the transparency group end up written in the same bands as the group push rather than all bands like the normal blend parameter change compositor action does. A few changes were needed in the clist compositor writing code to make sure that this special blend parameter change did not push a new cropping item on the cropping stack. This commit results in a lot of progressions. However, the cluster push revealed a couple files fts_06_0608.pdf.pdf.ppmraw for example, which may have an issue. These are being checked and if found to be an issue a new bug report will be filed.

pdfwrite enhancement : attempt to make PCL bitmap fonts into searchable type 3 In general pdfwrite only resorts to making a bitmap from a font when it cannot handle the original font type, which is rare for PostScript, PDF and XPS. However all PCL bitmap fonts are handled this way. When this happens, the bitmap is stored into a general type 3 font, a 'bucket' where all such glyphs are stored. When this font is full, a new one is started and so on. The text stored in the PDF page stream references the correct type 3 font, but usually the character code will be unrelated to the original character code. For PCL bitmap fonts pdfwrite actually starts by creating a type 3 font to hold the PCL bitmaps, but doesn't use it. This patch tries to store the bitmaps in the type 3 font where possible, using the character code from the original PCL document. Although this will not create searchable text in the general case, it does seem that there are a good number of PCL documents which do use an ASCII encoding and so will produce a searchable PDF file. There are several caveats: 1) This only works at all with cached glyphs. Glyphs which are too big to fit in the cache are instead rendered as images, not text at all. The cache has a compiled limit of 2500 for the height of the bitmap, but this needs to take the resolution which is being used for rendering into account. The default resolution for pdfwrite is 720 dpi which means that bitmaps larger than ~125 rows will not be cached. (see below for more) 2) Certain kinds of text operations can't be handled at all; any case where a character code does, or may, exceed 256 cannot be handled. These cases are handled as before by placing in a special font with a unique character code and called from there. 3) If the font matrix is not the identity we cannot handle the glyphs, as the bitmaps stored in the cache already include any transformations present in the Fontmatrix and we can't undo those transformations to the bitmap. In practice this means that if the canvas orientation (not the media) is not portrait, then this will cause the text to be non-searchable. 4) The Acrobat searching algorithm does not work very well with this kind of text. In our case each glyph is individually positioned on the page rather than being written as a continuous stream of characters. Acrobat seems unable to find more than about three glyphs in succession this way. There is no further scope for improvement in pdfwrite as far as I can see. The only way to handle this better would be to make changes in the PCL interpreter so that the bitmap PCL font is created as an actual font (probably a TrueType). This would mean that the text would be stored in the PDF file as real text, the FontMatrix would not be a problem, caching would not be an issue. This is probably a large project, but I suspect less of a pain than this enhancement was. Caching ======== In gsfont.c is a #define: #define blimit_LARGE 2500 /* blimit/upper - max size of a single cached char */ Increasing this will allow larger glyphe to be cached. There is another limit in gxchar.c: static const uint MAX_TEMP_BITMAP_BITS = 80000; This should not be altered. Care should be exercised if increasing the maximum size of cached characters as these are emitted in the PDF file as inline images in a type 3 font. The PDF spec recommends that inline images should not exceed 4Kb and some consumers may not be able to cope with images which exceed this limit.

Revert revision 11901. Because of the way that PCL draws bitmap fonts directly to the cache there is no possibility of making uncached glyphs work properly. Also the code for cached glyphs is much too forgiving and attempts to add glyphs which cannot be handled. Finally there is no provision for type 3 fonts with non-identity matrices. Because the bitmaps in the cache already have the scaling/rotation/shearing and clipping applied, we cannot have a type 3 font with a non-identity matrix. The code will be revised and recommitted.

Two changes to the local cluster system: 1. A warnings check is now performed on the code under test (both commit and user tests). 2. In order to better recover from nodes going offline near the end of a cluster run nodes are paused after all their jobs have been sent. This way the jobs from an unresponsive node that isn't detected until all jobs have been distributed can be reassigned. Also some minor cleanup (dividing the clustermaster log into .log and .dbg files, supressing some uneeded debugging messages, etc.)

Fix for PCL that uses the chunk allocator (which is not inherently thread safe) when NumRenderingThreads > 1. Adds 'is_thread_safe' to the gs_memory_status so that clist_setup_render_threads can wrap an unsafe allocator in a locking wrapper. Also restore the optimizations to the chunk memory allocator to keep two lists (one for multiple object chunks and another for single object chunks) and fixes the chunk_free_object so that the correct list is chosen. Even if not found on the selected list, the other list will be scanned and a diagnostic printed if the wrong chunk list was selected (belt and suspenders). My testing with the lj*.prn files did not show this problem.

Fix so that the initial gray color spaces in the graphic state are properly color managed. Previously, if we immediately started drawing in the document with a gray color space, the initial un-managed color space in the graphic state was used and this was not associated with the specified gray source profile. With this fix we initialize the stroking and filling color spaces to be ICC color spaces associated with the profile for default_gray in the icc manager. Also a fix for an issue in littleCMS. When merging profiles, littleCMS will often do an optimization where it approximates 1-D LUTs with an exponent operation for use during merging and interpolation of the profile structures. If the curve is very steep, as in like a step function, it should not do this approximation. This was an issue when we had profiles that provided thresholding operations with their 1-D LUTs. I spoke with Marti about this issue a couple weeks ago. This commit will create over 6000 differences in the regression test. I reviewed many of these and they all are minor differences in gray colors as expected. These are differences where we were drawing unmanaged colors.

pdfwrite enhancement : attempt to make PCL bitmap fonts into searchable type 3 In general pdfwrite only resorts to making a bitmap from a font when it cannot handle the original font type, which is rare for PostScript, PDF and XPS. However all PCL bitmap fonts are handled this way. When this happens, the bitmap is stored into a general type 3 font, a 'bucket' where all such glyphs are stored. When this font is full, a new one is started and so on. The text stored in the PDF page stream references the correct type 3 font, but usually the character code will be unrelated to the original character code. For PCL bitmap fonts pdfwrite actually starts by creating a type 3 font to hold the PCL bitmaps, but doesn't use it. This patch tries to store the bitmaps in the type 3 font where possible, using the character code from the original PCL document. Although this will not create searchable text in the general case, it does seem that there are a good number of PCL documents which do use an ASCII encoding and so will produce a searchable PDF file. There are 3 parts to this enhancement: 1) Cached glyphs. When the current font is a type 3 font, and the text operation is one which might result in an ASCII character code, and we can manufacture a glyph name for the resulting character code, store the glyph in the type 3 font (rather than the general 'bucket' font), using the character code and glyph name. Glyphs which can't be handled this way for any reason are still stored in the general recipient 'bucket' font. 2) Uncached glyphs. Glyphs which are too large for the cache are rendered as images. The image handling code has been extensively reworked to try and detect this situation and, if the criteria for cached glyphs above also holds true, to store the image as a glyph in a type 3 font and draw text in the PDF content stream instead of an image. Images which do not fulfil these criteria are still handled as images. 3) Recached glyphs. If the glyph cache fills up, glyphs will be flushed to make space. If a glyph is then reused we go through the caching case again (for large glyphs which are uncached we end up repeating the code every time the glyph is used). We now attempt to spot this by determining that the glyph in the font has already been used, and rather than storing a new copy of the glyph, as the old code did, we simply emit text into the page content stream. Note that there is a recommendation that inline images in PDF should not exceed 4KB. Since CharProcs must use inline images, bitmaps which exceed this size will be rendered as images, not text (they will also exceed the cache size and so are always rendered uncached).

In the event that we've decided not to cache a glyph generated by FAPI, we need to make sure that zsetcachedevice2() doesn't opt to try to cache said glyph. To do that we were setting in_cachedevice to CACHE_DEVICE_NOT_CACHING before calling zchar_set_cache(), and setting it back to its previous value on return. Unfortunately, a font with a CDevProc causes the call to zsetcachedevice2() to be delayed until after execution of the CDevProc, so in_cachedevice was (probably) no longer set to CACHE_DEVICE_NOT_CACHING. Amongst other effects, this caused some anti-aliased glyphs to be render with incorrect, scaling as well as the potential for marking glyphs to have empty (but valid) cached bitmaps. Expected cluster differences: fts_23_2306.pdf at 72dpi shows some (benign) pixel differences on the pattern filled glyphs - this is actually a behaviour progression, as it is caused by cache being properly bypassed for an uncached glyph, rather than the glyph being rendered uncached but the cache receiving an emtpy glyph. Bug 691750.

Marcos points out that tiffscaled with -rR -dDownScaleFactor=D can produce different sized images than just using -r(R*D) and a normal tiff device. (Bug 691730). I'll concede he's probably right that this isn't ideal. The difference was caused by me rounding the size up on a downscale so that no information is lost. This patch removes the rounding up.

Work around the "no rule to make target" with tif_config.h (actually it affects tiffconf.h, too). This involves the rather unpleasant requirement of calling a configure script (for libtiff) from a makefile (the top level makefile for the ghostpdl builds). It must be done there, before the PDL specific makefiles start setting CFLAGS, which confuses the configure. Also, update the GS dist-clean and GhostPDL clean targets to remove the two tiff header files generated during the tiff configure. THIS IS NOT A FIX! It really is a "workaround". Bug 691700.

Code to speed up cases where a file contains a lot of small images that are embedded in the clist as high level images. Previously, for every high level image, the serialized ICC source data was read out of the clist at a different clist file location, which required a fseek, a fread and then another fseek. This occurred even if all the images shared the same profile. The cost of file i/o for this can become significant if we have a lot of images. With this commit, the reading of the profile data is delayed and will only occur if a link using that profile does not already exist in the link cache.

The documentation says they should all default to applying it, but be controlled by the option. In this commit, we change so that all black and white tiff based devices (except tiffscaled) respect this parameter. We default to applying it in fax devices, and not applying it in non-fax devices, so default behaviour does not change. We also update the docs. No expected differences.

Fix bug reported by Norbert Janssen. Inaccuracies in the floating point maths can cause 'no-scales' to look like 'downscales', and so high level images are skipped. This shouldn't actually matter in most cases as the two rendering paths should give the same results, but when people hook the clist for their own purposes this can cause problems. The workaround is to introduce a fudge factor and to accept very slight downscales. Thanks to Norbert for the first version of this patch. Minimal differences in cluster testing due to bug 691697.

Add Rays MinFeatureSize magic. Ray had originally integrated this into the fax devices, which had the effect of working for the tiff based fax devices too. Unfortunately the reworking of the tiff based devices to use libtiff meant that the output function changed, causing the patch to stop working with those devices. Here we split the new code out into a separate .c/.h pair, so it can be used by both tiff and fax devices, and hook it up to all the black and white tiff devices (except tiffscaled) and to the fax based ones. We also document the device (including it's current limitations). No expected changes.

Fix pdfwrite : Do not emit DeviceRGB/CMYK as an Alternate when disallowed by PDF/A or X If a /Separation colour space had an /Alternate of /DeviceRGB or DeviceCMYK it was not checked to see if it was valid for PDF/A or PDF/X production, if these were set. As a result invalid PDF/A or PDF/X files could be written. The code now tests these flags and if the base space is not valid, converts to an appropriate base space by; sampling the tint transform function at 0 and 1, converting the resulting colours to the appropriate base space (using the Red Book methods for DeviceRGB/DeviceCMYK conversion), creating a new linear interpolation function for the new base space, using the converted sampled values for /Co and C1. The new base space is then written to the PDF file. No differences expected as we don't test PDF/A and PDF/X on the cluster.

Add a helpful valgrind header, and call it from gsmdebug.h. The valgrind header here serves 2 purposes. Firstly, it insulates us from platforms on which Valgrind does not exist - if we build without defining ENABLE_VALGRIND then no dependency on any valgrind headers exists. The standard Valgrind macros are all defined in this header to do nothing, so they can safely be called in our code without needing ugly #ifdef ENABLE_VALGRIND wrapping. Secondly, it insulates us from changes in the valgrind/memcheck.h file - if ENABLE_VALGRIND is defined we will use whatever version is defined by the system. If new macros are defined by new versions of valgrind/memcheck.h we simply need to add new 'empty' definitions to valgrind.h. To start with, the only use of this code is to mark the contents of newly allocated blocks as being undefined. Thanks to AlexCher for spotting a cunning place to do this.

Disable the use of high level images in the clist if we are downscaling; this serves 2 purposes. Firstly, it fixes the potential problems with banded/unbanded mismatch of rendering due to the 'support' calculations done in the high level image code. These calculations are no longer correct for downscales since the change to use a simpler interpolated image scaler. Secondly, when downscaling we will probably end up copying more data than we would if we just kept the original, so high level images are a bad idea anyway. This *should* produce no differences, but actually produces lots. Most of these might be ignorable (slight rendering differences that appear to result in the new images being a little lighter, but a significant number appear to be noticable progressions, which hints that the high level image clist code is broken. Specifically high level images fail to render the same as the non high level code does. In particular halftoning seems to be enabled for some examples when high level images are used, for no good reason. This has been opened as bug 691697.

Fix (pdfwrite) : Update CFF interpreter to handle gsubr while searching for SEAC Bug #691680 "PDF Writer drops many accented characters" pdfwrite makes use of a routine 'gs_type1_piece_codes' while copying fonts to determine if a glyph is a SEAC, and therefore includes two subsidiary glyphs. This code was updated previously (rev 10076) but on encountering a callgsubr in a CFF font, assumed that the glyph was not a SEAC> This patch adds support for callgsubr and continues searching glyphs which use a gsubr to see if the gsubr is actually a SEAC type endchar.

Fix (pdfwrite) : Scale up type 3 font outlines to give more accuracy Bug #691383, #691287, #691595 various type 3 font problems. Although this is being fixed for the FreeType implementation, the Artifex font interpreter had similar problems. The issue is caused by using an identity scale at 72 dpi to capture font outlines. Quark often uses a type 3 font which runs a type 1 font, in order to achieve text special effects, such as stroke+fill. The stroke was achieved by a 'charpath/fill' combination, because pdfwrite doesn't have a charpath, this meant that the path was captured and emitted. Because the scale was so low, the interpreter could run out of arithmetic precision, resulting in poorly formed outlines. We can't simply use the CTM in force at the time, as that includes the font scale, but we need to use something other than the identity. A scale facto of 1000 proved too likely to cause arithmetic overflow, or clipping, and also meant writing large values to the PDF file, which is inefficient. A factor of 10 turned out to be insufficient, so a factor of 100 has been used. Because the CharProc is effectively interpreted at the page level, this can result in large values being used for paths, so we need to scale the device width and height by 100 as well, to prevent clipping (and undo it afterwards!)

Fix (pdfwrite) : Properly scale co-ordinates into Acrobat's range When emitting various co-ordinates pdfwrite is careful to stay within +/- 32,767 in order to ensure all versions of Acrobat can properly deal with them. To achieve this it emits a matrix which scales values up, and then writes the co-ordinates scaled down by this factor. Thus ensuring that they stay within permitted values, but are still correct. However, when emitting a rectangular fill, the scale was applied backwards, the co-ordinates were scaled *up* instead of down by the scale factor. This led to wildly incorrect values being written for rectangular paths. No differences expected with this in the test suite, however it forms part of the fix for type 3 fonts which will follow and does rely on this change.

Add new tiffscaled device. This renders internally as tiffgray, but then downsamples by an integer scale factor (specified by -dDownScaleFactor=n) and error diffuses to 1bpp output.

Update interpolation filter. When we are downscaling an image on either axis we now use a simpler (less computationally complex) linear interpolation filter rather than the existing mitchell filter. For downscaling the difference in quality between mitchell and simple linear interpolation is not that noticable. (But the CPU/memory usage is a quarter what it would be for proper mitchell downscaling). What is noticable is that the existing downscaling code is 'bent' to avoid having to hold more than 8 temporary scaled scanlines of the image. The effect of this is to incorrectly limit the pixels that actually go into contributing to an output pixel, producing dropouts. We update the code here to remove this limit. This means that downscales may potentially take more memory and more computation to perform, but the overall quality is better. Regression tests show both noticable and unnoticable differences in files that enable interpolation (270 or so). The noticable differences are all that the new output looks smoother, at the expense of losing some contrast and solving some 'jaggy' looking edges. Testing with my custom dropout test file shows a huge improvement with the new code. I'll add this to the test repo shortly.

Fix for a large memory leak that can occur when a pattern cache entry is freed and a transparency buffer exists in the entry. A problem was that the pdf14 device, which contains pointers to the buffer, had its close device procedure set to forward due to the device being set in a disabled state during pattern_paint_finish. The close device proc for the pdf14 device contains the calls to actually free the buffers so this was not occurring (instead we were forwarding to another device). In addition, the pdf14 device itself was not being destroyed. With this commit, when the pattern entry is freed, the pdf14 device is now closed, which frees the buffers, and the pdf14 device is properly reference count decremented to result in the device itself getting freed. Regression run revealed no problems.

Fix (pdfwrite) : Process text in Tr 3 even if the Widths are non-standard Bug #691605 "Invisible text not preserved by pdfwrite" The problem was that if text in text rendering mode 4 (neither stroke nor fill) used a font where the entries in the FontDescriptor /Widths array did not match the actual widths in the font, the code took a path where the glyphs were not added to the 'used' list, and so were never emitted. Text in regular fonts where the /Widths array was missing, or matched the widths in the font (as the spec says they must) worked correctly. Fixed by processing text whose operation properties include TEXT_RENDER_MORE_3 the same as text with the TEXT_DO_DRAW property.

Fix (pdfwrite) : Check encoding compatibility when finding base fonts Bug #691656 "crash in Chinese font: /typecheck in --.FAPIBuildGlyph--" A typecheck error is not a crash of course, but when using the built in font interpreter this did not produce an error, silently discarded the text instead. This was still incorrect. The problem is caused when dealing with type 0 fonts and producing multiple type 1 fonts to handle the large number of glyphs. The code for finding an existing font (in order to minimise the number of new fonts) or create a new font, did not consider the encoding of an existing font when trying to match it (this did work for regular fonts). This could lead to a font with an incompatible encoding being used, which caused an error later in text processing where a routine is supposed to be guaranteed no font encoding problems. That led to an attempted fallback to the 'bitmapped type 3 font' solution, but the text processing was passing ridiculous values to the font interpreter. In the old font code this caused a silent discard of the text, with the FreeType code it produces an error. Fixed by checking the base font we find to see if its encoding is compatible with the current text encoding, and manufacturing a new font if it is not. No differences expected.

Put back some statements. It turns out that we can either have gcc be warning free or the static analysis warning free. The problem is gs_note_error which uses gs_log_error, on a release build gs_log_error is defined as the error value. If we don't do something with that value then gcc complains that the 'statement has no effect'. So the code was set like this: ecode = gs_note_error(error code); But if we want to actually ignore the error and just note the problem, then we don't use ecode and the static analysis complains that the variable is unused....

Fix for part 1 of bug 691484 - uninitialised memory usage in clist code. The FAPI code copies bitmaps and pads them out so that each raster line is appropriately aligned. Previously the padding bytes were left uninitialised. Unfortunately the clist code reads the padding when compressing the bitmaps, which a) upsets valgrind and b) means that the exact size of the clist will vary from run to run. Here we tweak the copying code to ensure that the padding bytes are always set to zero. No differences shown in local cluster. This solves part 1 of the bug.

Fix (pdfwrite) : ConvertCMYKImagesToRGB not working Bug #691647 "-dConvertCMYKImagesToRGB no longer works" Originally caused by the conversion to the ICC workflow, which meant that all images appear to be in a ICC space, and only images originally natively CMYK are converted. Probing the ICC space using the provided utility to return the original colour space allows the code to work, but reveals a more serious error. The code in psdf_setup_image_filteres() alters the image colour space and decrements the reference count of the original colour space. This seems logically correct, and in one of the three calling paths it is correct, but under one of the other two conditions it causes a crash. The routine pdf_begin_typed_image_impl() makes two copies of the original image parameters, and when it does so it does *not* increment the reference counts of any counted objects. This copied data is presented to the image filter setup several times, and if CMUK to RGB conversion is going on the original colour space is decremented each time. This leads to obvious problems. The simplest solution would be to increment the reference counts when the copy is made, but that would mean checking all the error condition break outs, and decrementing the reference count in each case. Since the colour space is only decremented in the filter setup, this patch increments the count before the call, and if the colour space is the same afterwards (whether an error occurred or not) decrements it back again. If the colour space changes we do not decrement the space of course, as the filter setup routine has done that. In addition, extended the test for whether CMYK images should be converted to include the original test of the native space, in case we get here after an image has been converted to a base space and no longer has an ICC space. No expected differences, this configuration is not tested by the regression suite.

Fix (pdfwrite) : allow for UserPasword and OwnerPassword in page device Bug #691256 "OwnerPassword and UserPassword don't work as device parameters" pdfwrite sets up encryption filters when the device is opened, and the device is not (currently) closed until Ghostscript shuts down. This means that changes to the page device dictionary which require a restart (eg the encryption parameters) do not affect the current setup, though they may be (incorrectly) written when the device is closed. This patch addresses the specific issue of OwnerPassword by closing the device if the password is changed *and* we have not yet written any pages. If we have already begun the output when a password change occurs then we ignore it and flag a warning. This is also a first step in the direction of making pdfwrite open and close properly so that we don't need to restart Ghostscript to use it. No expected differences.

Fix (pdfwrite/ps2write) : Don't dereference mask colour spaces Bug #691106 "-sDEVICE=pdfwrite -dConvertCMYKImagesToRGB=true" When checking to see if an image needs to be converted to RGB, the image space is checked to see if it is CMYK. However an image mask does not have a colour space (it is NULL), firstly so that we can tell its an image mask, and secondly because masks genuinely do not have a colour space, they take on the current colour. Attempting to dereference the NULL colour space causes a crash. Since a mask never needs converting to RGB, we short circuit the test by detecting a NULL colour space.

Fix so that objects tag information makes it through transparency rendering AND the clist. An issue was that the pdf14 encode and decode procedures are used as opposed to the target device encode and decode procedures and it is through a value in the color index that we currently communicate the object type through the clist. When we are in page rendering mode, it is easy to get the current object from mem->gs_lib_ctx->BITTAG, but this is not set correctly in clist rendering if for example a glyph is stored in the clist as a mask fill. Instead the information about the object is extracted from the color index. So, to make this work, we had to introduce an encode method for the pdf14 device that incorporates the tag information and also make sure that the bit depth for the pdf14 color info value is incremented appropriately so that the extra byte is stored and extracted from the clist. The object type is then recovered during the pdf14 mark fill rect procedure. This was tested with the updated bitrgbtags device using a custom file that has overlapping text, image and path objects with varying transparency amounts.

Final part of the fix for bug 691612. Currently the code blindly sets the "lop_pdf14" whenever the pdf14 device is in use. This forces the 'lop_is_idempotent' test to fail, which in turn forces slower cases to be taken through the code. This patch alters that logic, so that the pdf14 device can leave that bit unset if the parameters are set up in such a way that the lop really can be idempotent (i.e. normal blending, solid alphas etc). This vastly improves the speed of rendering non-alpha content, so we are no longer penalised for having just a small amount of transparent content on a page. Testing shows 398 files that change, but bmpcmp reveals these all to be very small changes to do with whether individual pixels are filled or not. This is consistent with the typical mismatches between special case and normal renderings, so can safely be ignored for now.

As part of the investigation into bug 691612, we noticed that the clist band playback code doesn't call the device stroke_path method, but instead calls the default implementation directly. In order the fix the bug, we'd like it to call through the device version (pdf14_stroke_path). Consensus is that it's an oversight that it's not calling the device version already, and tests indicate no differences (*) so this patch changes it to call via the vector. (* Actually regression testing shows 2 pdfwrite differences, but they are in unbanded tests, so can't be executing this code, so are probably just indeterminisms).

Fix (pdfwrite) : Do not write Encodings with Symbolic TrueType fonts Bug #690744, #691036, #691319. The PDF specification makes it clear that Symbolic TrueType fonts should not have a FontDescriptor which contains an Encoding entry. pdfwrite has specifically been doing this, the reason being (code comments) : * We write True Types with Symbolic flag set. * PDF spec says that "symbolic font should not specify Encoding entry" * (see section 5.5, the article "Encodings for True Type fonts", paragraph 3). * However Acrobat Reader 4,5,6 fail when TT font with no Encoding * appears in a document together with a CID font with a non-standard CMap * (AR 4 and 5 claim "The encoding (CMap) specified by a font is corrupted." * (we read it as "The encoding or CMap specified by a font is corrupted.", * and apply the 1st alternative)). We believe that AR is buggy, * and therefore we write an Encoding with non-CID True Type fonts. * Hopely other viewers can ignore Encoding in such case. Actually in this case * an Encoding doesn't add an useful information. Since this is working around a bug in old versions of Acrobat, and the presence of an Encoding causes preflight errors and is specifically forbidden in PDF/A, this work around has been removed. I would like to check recent versions of Acrobat to see if this issue persists, but am unable to find an example file. The change predates the adoption of Subversion, the first logged change is October 2003.

Addition of support to enable persistence of objects tag information through transparency rendering. In the current code base, transparency blending erases all knowledge about the objects that were drawn and blended, setting the entire object to image type. With this commit, the tag information is retained through blending by doing a bit-wise or of the tag values. When a device supports tags, the pdf14 device will create an additional plane to maintain the tag data information. Blending of the tag information occurs in pdf14_mark_fill_rectangle, pdf14_mark_fill_rectangle_ko_simple and pdf14_compose_group. A new device procedure called put_image is added. This is called by the pdf14_put_image operation, which enables the communication of the tag information to the target device. pdf14_put_image will first attempt to pass the alpha channel and the image data not scaled by the alpha channel and the tag data to the target device. The planar offset location of the alpha and tag data is communicated in the put_image procedure interface. If the target device cannot handle this form of the data, it should return 0. The pdf14_put_image operation will then blend the alpha data and attempt the put_image again but this time with an alpha offset of 0 to indicate that there is no alpha data. Note that the alpha data remains valid for those devices that still want the alpha but also want to have the graphics library do a premultiplcation of the alpha with the data. Details of this interface will be added to the documentation. In addition, the bitrgbtags device is being updated to demonstrate the use of the put_image procedure.

Another partial fix for Bug 690993. The sole remaining Valgrind warning is that memcpy is called on overlapping src/dst blocks in cmd_read_data. Investigation supports this, and suggests that we should be using memmove instead. This does stop the error, and leaves us valgrind warning free. This also appears to resolve the indeterminism, in that repeated runs of the command line given in the bug return identical results. The bug remains open though, as there is still a mismatch between banded and non-banded mode. No expected differences.

Partial 'fix' for Bug 690993. When encoding a bitmap into a clist, we copy it into a block with potentially larger padding requirements. These extra padding bytes were left undefined, causing subsequent attempts to compress the bitmap to cause valgrind to give warnings. The fix is simply to introduce and use a new function that copies a bitmap and zeros the padding. This should eliminate the warnings, produce better compression, and (more importantly) mean that every run uses the same amount of memory, hence eliminating potential odd effects where clists may be of different lengths on different runs. This still leaves bug 690993 open. No expected differences.

Fix (ps2write) : Bug #689419 "Text missing if nested BT with opdfread.ps" Type 3 fonts which select another font and then draw text from it (a common feature of Quark Xpress) can result in nested 'BT' operators when processed by ps2write. The opdfread prologue does not cater for this, specifically the TextMatrix is not saved and restored around a BT/ET pair. If the text matrix is altered by the font selection, then the 'ET' will not restore the old matrix leading to incorrectly sized or disappearing text. The patch (supplied by SaGS) saves the TextMatrix in a stack (stored in an array) and restores the matrix after an ET, in case it is nested. Currently this allows for nesting up to 20 deep, which should be more than adequate. Note that if we were to encounter a nested BT with no ET this would still fail, but in this case the file produced by ps2write would be invalid, and the missing ET should be fixed. No differences expected, the regression suite doesn't test ps2write.

Fix (pdfwrite) : Don't colour convert SMask images Bug #690612 "PDF sRGB conversion loses images" The handling of SMask images in pdfwrite is a bit convoluted. These are handled by converting initially to a DevicePixel colour space, then detecting that later and replacing with a DeviceGray space. However, after doing so, if ColorConversionStrategy was set, the space (and image samples) would be converted to another colour space. This is not legal for SMask images. This code simply checks to see if the image is an SMask before setting colour conversion and doesn't convert the colour space/samples if it is and SMask. No expected differences.

pdfwrite enhancement : performance improvement with type 3 fonts Bug #690575 "PS to PDF Conversion extremely slow (possibly endless)" The type 3 font code assembles CharProcs for type 3 fonts by writing them individually into a 'cos_stream'. Each time a new one is completed it is compared to all the existing CharProcs to see if it is a duplicate. This was done by fseek/fread/memcmp operations. As the number of CharProcs increases, the time spent seeking, reading and comparing the data increases dramatically and performance becomes very poor. Not only that, but the test is actually done twice for each new CharProc. This patch tackles the problem by creating an md5 hash of the data written to a cos_write_stream (a subclassed cos_stream) as it is written. The cos_stream 'equal' routine checks to see if the md5 hash is valid and if it is then compares the hashes. If the md5 hash is not valid (ie not a cos_write_stream) then it uses the old seek/read/compare mechanism. This will improve the performance of any stored data if it is stored using a cos_write_stream and compared against other data of the same type. (I don't believe we do this anywhere else currently, but I'm not suer) This does improve the performance significantly, and the code no longer spends most of its time waiting for I/O operations to complete. It is still slow, but this is the result of using lots of type 3 fonts. Because of the way these must be processed in order to capture the outlines they are never going to be fast. In my test this runs 2-3 times faster than before. There should be no differences in output from the old code.

Bump version number to 9.01 and associated changes.

[base/gscdef.c base/version.mak Resource/Init/gs_init.ps]

## Version 9.00 (2010-09-14)

This is the first release in the stable 9.x series.

This release includes a move to an ICC-based color rendering workflow. The design allows easy integration of 3rd party color management modules (CMMs) and management of DeviceN and spot source colors with ICC profiles as well as with non-ICC proprietary methods. The default CMM is the well known littleCMS. Postscript color objects and non-ICC CIE-based PDF color spaces are converted to equivalent ICC profiles enabling complete color management for all color spaces by an ICC-based CMM. New command line options enable the specification of gray, rgb and cmyk default ICC profiles as well as output device ICC profiles. The new work flow provides performance improvements in the rendering of images, shadings and transparencies. In addition, the color conversions are designed to work efficiently in multithreaded display list (c-list) rendering through the use of a shared link cache. Finally, proper ICC based rendering now occurs for ALL XPS objects including Named colors, N-Channel colors and images with internally embedded ICC profiles.

The second major change in this release is that glyph rendering for all font types except Type 3 is now handled by Freetype (via a much improved and enhanced Font API). The most obvious benefit of this is a complete, and proven implementation of the TrueType byte code interpreter (now unencumbered by patents).

Another major change is that the Postscript interpreter's graphics state now stores two separate colour space settings for stroking and filling, to better support the stroke and fill colours required by the PDF interpreter.

Finally, support for optional content has been added to the PDF interpreter.

This release also includes a number of improvements to the pdfwrite device to improve reliability and quality with PCL and XPS input. Many improvements to the support of JPX images in PDF files, PDF annotation rendering and the usual number of general bug and robustness fixes.

For security reasons, Ghostscript no longer searches the current directory by default. Use -P option to revert to old behavior.

Another revision of the FAPI code. Due to a problem in Freetype which needs further investigation, we cannot produce an outline, then decide to produce a bitmap if it is small enough. We work around this by producing a bitmap, and if it is too large, dispose of it, and retry with an outline, thus although we still risk larger than ideal memory use, it is very short lived. A glyph too large to be cached (for which we will now usually use an outline) does not suffer from the Freetype issue mentioned above. The maximum allowable bit for Freetype to produce is now 1.5 x the maximum cache bitmap as set in the Postscript state - it is set larger than the cache bitmap since it is *vital* that if GS expects a bitmap to be cache we supply a bitmap. Given that the bounding boxes arrived at the GS cache device and the Freetype rendering code arrived at slightly differently, there would be the chance of edge cases where FAPI would produce an outline, when the cache expects a bitmap. Allowing FAPI plenty of leeway avoids that. The calculation to convert a quadratic to a cubic spline in the Freetype interface code was slightly wrong. Also, FAPI now sets the fill adjust to 0 for filling outline glyph, instead of inhereting the value from the originating graphics state, which gives *much* more consistent output between the bitmap and outline cases, and addresses the slightly excessive boldness observed for outline glyphs since the adoption of Freetype/FAPI as the default font scaler/renderer. Finally, support for the existing Ghostscrit text anti-aliasing capability is improved. Bug 691604

Fix to enable proper mask filling with patterns that have transparency. Major change is in gdevp14.c where begin_type_image and mask_fill procedures now will (if we are filling with a pattern that has transparency) push a transparency group. When we are finished processing the image, the group is popped which enables proper blending. There remains an issue with a special file that Ken created when it is run in c-list mode. A new bug will be opened for this issue. Thanks to Ray for helping with this project and finding a bounding box issue in the creation of the transparency group during c-list reading.

Fix (pdfwrite) : incorrect pattern matrix calculation Bug #690504 "ps2write does not work with asymmetric resolutions, like 600x1200dpi " The problem was caused by frankly totally incorrect calculations when generating the /Matrix for a pattern. Because we always see the CTM including the resolution scaling but need to output a matrix with this removed, we scale the CTM by the inverse of the resolution scaling. But the calculation simply divided the CTM through by the scale factors, which is totally incorrect and fails badly if the matrix involves rotation. The code now correctly creates and multiplies a scale matrix. Note, the order of multiplication is important here. No differences expected.

Slight refinement in the how the FAPI character generation detects we are producing anti-aliased glyphs. Also, it seems that when assigning variable value to a second, larger data type, whilst gcc promotes the data type before the assignment, MSVC promotes the variable later, so shifting a 32 bit integer up during an assignment to a 64 bit integer variable works find on gcc, but MSVC loses the most significant bits. So we need to force the promotion to happen with a cast. Bug 691588

Some fairly substantial changes to the FAPI code to get very high resolutions and anti-aliased text working reliably. For AA text, we now make *sure* to produce outlines for non-cached glyphs, thus the GS path code can anti-alias correctly (for cached glyphs, the "show" machinery does the anti-aliasing from the cache bitmap). The high res problems were highlighted by the bbox device (which runs at 4000 dpi). To resolve these the width and height parameters for Freetype had to have value overflow compensation added, to match the existing underflow compensation. FAPI/Freetype also now will only create a glyph bitmap if the bitmap size is smaller than the allowable glyph cache bitmap. It may still produce a bitmap for a non-cached glyph, if the cache is full, but the individual glyph bitmap is not larger than the allowable glyph item - this is allow for better consistency when we're near the limit of the total cache size. Finally, the FAPI outline retrieval code now requires 32.32 fixed point variables (rather than the previous 16.16), which prevents overflow, and improves accuracy. If also provides us with the opportunity to check for overflow/underflow of the GS internal fixed point variables, before calling the GS path code. There are quite a few cluster changes. I have checked them all, and one is a progression (missing glyphs now render) and the rest are the pixel level differences expected by having GS render a path, rather than Freetype - most are due to Freetype grid fitting to the glyph bitmap, and GS grid fitting to the page raster.

Fix (pdfwrite) : string not being re-encoded Bug #690441 " Files render properly with gs, but are misformatted by ps2pdf" A Coverity fix in revision 9072 prevented a crash, but also circumvented code that was essential to run under some conditions. (This is described by comments in the code as a 'trick'). The routine created a text string with the encoded text for a font with a custom encoding derived from a CIDFont with an unusual CMap. In order to avoid the potential crash, but still re-encode the string, which is essential, the relevant portion of the code has been copied and is exercised instead of executing 'pdf_reserve_char_code_in_pdfont()'. This produces the reencoded string we need, but if the encoding fails, where we would have caused a crash by dereferencing a NULL pointer, we instead return an error. No differences expected, we obviously don't have a test case in the regression suite.

More Windows batch file madness. Guard all path expansion with quotes, since the Windows command shell processor is too stupid to do so, even when expanding variables/arguments itself. Add a trailing separator to the %TEMP% variable before specifying the filename, as apparently some setups don't get a trailing separator by default. A paired separator (ie \\) doesn't seem to cause a problem so this ought to be safe even if the setup does have a trailing separator.

pdfwrite enhancement The addition of code to test and honour the 'embedding flags' in TrueType fonts has led to problems because PostScript producers are embedding type 42 fonts in the PostScript which are non-embeddable and worse use a custom non-reversible encoding, so that the resulting PDF file has garbage text when a normally encoded font is used as a replacement. It seems that Adobe has published a 'white list' of fonts which have been granted at least some embeddable rights. It isn't obvious if these are fonts which were type 1 (and therefore could be converted to TrueType and get incorrect embedding rights) or if the fonts were originally released as TrueType with the wrong embedding rights. In any event, this list has now been added to pdfwrite; if a font is encountered which has restricted embedding, then its name will be checked against this list, if it is found in the list then it will be considered as embeddable. We have already encountered one font on this list which has a slightly different name to the original (a space was removed) so spaces in the font names are ignored. This list will have to change over time, and we may find other examples of characters which we want to handle specially (eg oumlaut treated as o and e) No differences expected as this is not tested in the current regression suite.

Also, fix a few issues that existed with pdfwrites handling of those spaces, in particular adjustments are made for non D50 white points. D50 is the required white point for the ICC profile. About 189 pdfwrite test files will report differences. I went through them with bmpcmp. Since the profiles that were generated differ between gsicc_create and pdfwrite minor color differences exist. In addition, there were some regressions that existed, which this revision will fix.

Fix (pdfwrite) : linewidth corruption when Tr is 1 Bug #690436 " (regression) re-distilling pdf causes R graphics to go block-single-color." The problem was cause din the pdfwrite-specific text rendering routines. When the text render mode is 1 (stroke), the linewidth is adjusted by the current text matrix. However the routine to do this is called each time any element of the text 'graphics state' changes. So if multiple calls to (eg) Td were made, the linewidth would be altered even though there had been no change in 'w'. Fixed by getting the current linewidth before the text rendering routine, and setting it back to this value after the text rendering routine. No expected differences. However z400454b01d4-1.pdf seems to exhibit some minor differences which I am unable to reproduce locally. They are so minor that bmpcmp ignores them, and on my tests the PDF files are identical bar the date/time stamps and other metadata. I don't believe this is a real difference.

Fix (pdfwrite) : faulty matrix transformations for Pattern dictionaries Bug #690398 "Geometric issue with pattern" The problem is the definition of the default co-ordinate space. When a Pattern is at the page level or drawn inside a form, we need to remove our 0.1 scaling in order to return to the 'default co-ordinate space'. However, when painted on a form nested inside a form, the default co-ordinate space is the parent form, so we don't need to undo the scaling. This is the same problem addressed for shading dictionaries in revision 11347.

Fix (pdfwrite) : FormDepth not tracked properly. Part of the fix for Bug#690398. In order to know whether a pattern matrix should be converted to the top level CTM, or to an enclosing Form CTM, we track the Form Depth by noting when transparency groups begin and end (currently this is the only way to get a form output by pdfwrite). There was a problem with mask groups, because although pdf_begin_transparency_mask calls pdf_begin_transparency_group, pdf_end_transparency_mask doe snot call pdf_end_transparency_group. This resulted in the depth being incremented at the start of the mask, but not decremented at the end, so patterns could be emitted at the page level but with the CTM for a Form level, leading to missing content. Fixed by decrementing the FormDepth appropriately.

Enhancement - Font copying (pdfwrite) Bug #691573 " invalidfont in xshow". The file does in fact contain an invalidfont, the type 42 embedded fonts are defined by adding /.notdef to the CharStrings dictionary as if it were the Encoding array. The key /.notdef is added 256 times with values ranging from 0 to 255. Of course only the last one is actually defined. This means that when we come to copy the /.notdef glyph for our font copy, the type 42 GID is 255. However the font does not contain a glyph with GID 255, so the copy of the font fails. Although this is an illegal font, Adobe Acrobat Distiller does produce a PDF file from it. In order to duplicate this, code has been added when copying a font. If we fail to copy a glyph, and the glyph is /.notdef and the GID is non-zero, we try to copy a glyph with GID 0 instead. If that fails we error out, otherwise we use the glyph with GID 0. (TrueType font /.notdef glyph has GID 0) This works for the supplied file but is not, of course, a guaranteed solution since another badly formed font may not contain a glyph with GID 0.

Fix (pdfwrite) : errors in XMP metadata parsing Bug #691562 "ERROR -15 closing pdfwrite device". This use of a DOCINFO pdfmark exposed 3 separate bugs in pdfwrite's handling of XMP metadata. 1) Decoding an escaped PostScript string. Unescaped characters and octal escapes worked correctly, but non-octal escapes moved the index into the string one place too many. 2) The escape '\b' (backspace) wasn't handled and returned incorrect data. Although not tested by this issue, the form feed (\f) also wasn't handled. 3) When converting UTF16 data to UTF-8, the end of the destination (UTF-8) buffer was calculated incorrectly, causing a spurious buffer overrun error. The code now handles the missing escapes, does not advance the character position after decoding a non-octal escape and correctly defines the end of buffer. After this the Title string displays the same in Acrobat as the same pdfmark sent through Adobe Distiller. No expected differences as this only affects the document metadata.

The "shortcut" for rendering masks use by the FAPI code for uncached glyph bitmaps (gx_image_fill_masked) is only safe, in the general case when drawing "plain" colours to the output.

Enhancement : pdfwrite performance enhancement for pdfwrite when handling files with large amounts of text. Bug #689859 "Performance comparison versions 7.07 and 8.62 on HP-UX ia64" Alex's analysis shows that pdfwrite was spending a lot of time trying to to see if two type 1 fonts were the same before deciding whether a glyph could be added to a font, or was already present in a font copy. Most of the time was spent extracting and comparing /Subrs. The new code creates a hash (MD5) of both the local and global Subrs (if present) and stores that in the type 1 'data' field in the font (16 bytes). The hashes are created by pdfwrite only as they are required, so there is no performance penalty for rendering. The hash comparison is considerably quicker than the long winded Subrs comparison. For many files the performance difference is minimal but for file containing lots of pages, mostly composed of text, there is a considerable saving. The text files run in about 60% of the time they did before this change.

Free the pattern-clist devices that are created (and left for the GC to free) when pattern-clist patterns are used with a device that is using the clist for the page. Those that were allocated during the print_page clist playback would be those that leaked. Since the devices were closed, this could lead to GC referencing objects that were invalid. Related to, but not the final fix to Bug 691527.

This happened when -dMaxPatternBitmap=1000000 was used which is smaller than the default, confusing a HACK that attempted to force the use of the pattern-clist mode.

Fix pdfwrite There is a hack in type 3 font creation in pdfwrite which increases the FontMatrix if all the elements are very small, apparently Acrobat is unable to cope with very small FontMatrix entries. However, if all the entries are 0, it ends up running round a loop multiplying by 10 indefinitely. This change simply avoids the loop if all the matrix elements are 0. Naturally this isn't a useful font, its a Quality Logic test file.

This revision addresses that by only applying the fix to preserve glyph data when the text operation is TEXT_FROM_SINGLE_GLYPH as this is the only case where the affected union is a glyph not a pointer to a series of glyphs, and is therefore the only case which is affected.

Add a new paramter MaxPatternBitmap with a default value of 8Mb. Formerly the pattern_clist mode would be used when the bitmap size exceeded 1Mb and prior to rev 11___ this calculation was flawed and could allow pattern bitmaps as large as 64Mb to avoid the pattern_clist mode. While the clist based pattern tiling is slow, setting the threshold to 8Mb should be rare enough to minimize performance impact. Bug 691512.

The "show" machinery expected that even non-marking text operations (such as stringwidth) would result in a glyph bitmap which could be cached (assuming the glyph would be a candidate for the cache with a normal marking operation, like show). FAPI, however, did not create a glyph bitmap for non-marking operations, thus the cache would receive a valid, but "empty" glyph. This caused Postscript that used stringwidth before a show to sometimes "lose" glyphs, by using the empty cached glyph. FAPI's behaviour now matches the expectations of the show/cache management code. Causes cluster differences in Bug688372.ps, fts_31_3111.pdf, and 14-08.PS, these are all progressions. Bug 691517

Fix (pdfwrite) A piece of data (pointer to glyph data) was stored and passed into a routine 'process_text_modify_width' which expected the glyph data to remain unchanged but modified the text enumerator data. This doesn't work if the glyph data is a pointer to the text enumerator data. NB the text enumerator is saved and restored around the call. Modified so that the calling routine makes a copy of the glyph data before calling 'process_text_modify_width'. This should prevent 13-10.ps from entering an infinite loop.

Fix for Bug 691504 (gs taking a long time to render a file). Revision 8694 changes code from using a simple cast to an int to using a call to (int)floor. This fixes problems, but costs a factor of 3 in processing time for heavily tiled files. Here we change to using a macro version of floor instead. This removes the function call and NaN handling overheads and returns us to the same kind of performance as we had before. We apply the same change throughout the file (i.e. all the calls to (int)floor, not just the two changed in r8694. There is still scope for optimising this code further, but this closes the regression. No differences seen in local cluster testing.

This change makes x11 not depend on gsparamx.c and gdevemap.c (and not geeting them included in the shared library X11.so). gsparamx.c is part of psdf and is usually included and available, and gdevemap.c is small enough to be inserted completely where it is used. gdevxcmp.c is addressed by building it with $(GLCCSHARED) and not with $(GLCC).

Fix (pdfwrite) : try not to write out invalid xref Exposed by bug #691503. There are circumstances under which we create a reference to a /Page object which does not yet exist (creating an outline tree for example). In this case we create a reference to the page, and set its initial offset to the current position in the PDF file. When we later write the real object we update the position to reflect the point in the file where it is actually stored. However, if we don't actually ever write the object (in the case above, because LastPage is set before the destination page), then the object remains pointing to the wrong location in the file. This is then written into the xref table, and this confuses the current version of Ghostscript. The patch creates new pages with an offset of 0 (which is always invalid because the PDF header means the minimum offset for any object is 15). If the page is later created then the offset gets updated. If it is not written, however, we now check in the xref writing code to see if an object has an offset of 0. If it does, then we break the xref table up and do not write an xref entry for the missing object. Ghostscript is happy with this and processes the file. NB the proper fix is to not emit the Outline entry for the page which will not be present in the output, and a patch has been suggested to achieve this. This code has some uses, however, as it may prevent this kind of problem in the future. It also permits objects to be created and never referenced (presumably because they are never used) without leaving invalid entries in the xref, which might be useful. No expected differences.

Two changes for two primarily pdfwrite problems with FAPI/FT. The first is to only replace whichever of BuildGlyph or BuildChar procedures the original font actually contained, replacing both regardless confused some of "decoding" code elsewhere in GS (op_show_continue_dispatch()) and we ended up receiving a valid glyph to render instead of notdef. In this case we ended up incorrectly stroking a charpath (this was seen with Quark's Type 3 "special effects" font). With rendering output this resulted in a boldening effect on the glyph, in pdfwrite, the result was strange extra lines through the glyph. The second change is to due pdfwrite's use of a unit matrix for some of its work. This resulted in small glyph metrics rounding to zero within Freetype, and pdfwrite thinking a glyph had a width of zero. So make the scale value at which we consider a glyph to be "small" an order of magnitude larger, which gets compensated for in the calculation of Freetype's final matrix. Unfortunately this does cause ~2600 differences in the cluster tests: some are progressions, most are pixel differences due to rounding differences because the scaling numbers have changed in Freetype.

Fix bug #691493. Revert some of the work done for gs_2_colors. I had needlessly attempted to have 2 pattern_cache's, one for stroking colors and one for non-stroking colors. Given that the pattern_cache is indexed by color id number, this is not necessary as all the data can live happily in just one instance. This removes the problem seen in the bug (where it was getting into an infinite loop trying to populate the cache). Local cluster testing shows this produces 57 differences, all (I think) non-determinisms.

CUPS Raster output device "cups": Improved support for rendering jobs with high memory demands. Let Ghostscript determine the memory buffer sizes automatically (as it does with all the other output devices) if the environment variable RIP_MAX_CACHE is not set, zero, or does not begin with a number (like "auto"). If RIP_MAX_CACHE defines a valid value, use the actual value for BufferSpace and not 1/10 of it. MaxBitmap is the maximum buffer size to be used when rendering in full page mode, BufferSpace is the buffer size used in banding mode. Banding mode is used if MaxBitmap is too small to hold one page.

Add new gp_thread_start, gp_thread_finish abstraction, and deprecate old gs_create_thread function. Adapt multiple rendering thread code to use this new style instead. Hopefully this should solve the problems seen in rare cases when a test thread doesn't get scheduled until after the DLL has exited and the code isn't around any more. No expected differences. This code has been tested with MSVC and on linux with pthreads. While it should work with Borland and Watcom (as all the headers appear consistent) I have not been able to properly test it. Therefore the code is currently configured to fall back to the old code, thus hopefully guaranteeing that this commit won't make the operation under Borland/Watcom any worse than it is now. This fallback is controlled by a single define for each of these systems in gp_wsync.c, so it's easy to test. If users can report success with the new code we can remove the fallback trivially.

A much better solution for Bug 691328. The bitmap data coming from a font scaler/renderer may not have its raster alignment as Ghostscript expects, so in the event that is the case, create a bitmap which is GS compatible in the FAPI layer, before calling any further operations on it. This reverts the previous "hack" from r11362. No cluster differences expected.

Remove .dividesfnts procedure, which is not needed by PS interpreter after the introduction and use of string_array_access_proc() way back in revision 176. FreeType doesn't require a particular way to split sfnts either. ps2write includes procedures to create a well formed Type 42 from a TrueType font. The error is caused by .dividesfnts only spliting strings when the split offset is even. The sample file has a *long* run of cases where the split offsets are odd. When an even offset is finally found, the number of buffered bytes exceeds the maximum length of the string causing /rangecheck error. Thanks to Chris Liddell for the analysis of the problem.

Fix for bug 691478 Note that string objects that are maintained as user params must be either allocated in non-gc memory or be a constant in the executable. The problem stems from the way userparams are retained during garbage collection in a param_list (collected by currentuserparams). For some reason this param_list does not get the pointers to strings relocated during the GC. Note that the param_dict itself is correctly updated by reloc, it is just the pointers to the strings in the param_list that are not traced and updated. In this particular case, ICCProfilesDir sets a string in the icc_manager. When a reclaim occurs, the string is relocated (when in non-gc memory and when it is noted to the gc with the proper object descriptor). Then if a set_icc_directory occurs, the user params pointer has NOT been updated and validation problems will occur. Fix for this was to make the string not known to the GC and to allocate in non-gc memory. When icc manager is deallocated, the string is also deallocated.

Fix so that non-isolated transparency groups are rendered correctly. This fixes a rendering issue with fts_25_2524 and with a few in the test suite. A future optimization will be to avoid the extra buffer push if the blend mode is normal, since in that case we can draw directly into the parent buffer.

Fix for Bug691474. Source of error was due to icc hash code being read from clist after the transfer function. It should have been read prior to the transfer function. This was the first file we have seen that had a soft mask with a transfer function. Also fix for rendering of this file. The softmasks only uses the alpha channel as opposed to the luminosity of the object. Progression with CityMap-evnice.pdf in test suite. That file must have a alpha style softmask.

Update trunk to FreeType 2.4.1 The important change (from Ghostscript's point of view) is that the previously patented TrueType hinting operations have been enabled by default after the expiration of the patents in question. This change (the hinting being enabled) causes 3060 non-pdfwrite cluster changes, and 655 pdfwrite changes - these are expected, and are progressions.

Fix the bug that prevented recognition of GenericResourceDir/Category/Name as a valid resource path and required inclusion of GenericResourceDir in the search path to find the same resource by searching. New procedure does the following: 1. Returns GenericResourceDir/Category/Name if it exists. 2. Searches for Category/Name in LIBPATH. Returns actual path if found. 3. For non-existing resources return the same path as (1). Old implementation added GenericResourceDir twice, didn't close files, used system memory, called expensive procedures twice, etc. Regression testing shows trivial differences in 23-07.ps, which prints the length of ResourceFileName procedure. This is a partial fix for bug 691408.

Prepend icc directory to device profile name if the default name is used so that we have it during clist reading. This is a fix for the iccprofiles/ problem in 691408 when compile inits is not used. Also, fix so that the profile name is allocated in non-gc memory. This was a source of issues with the userparams dict not seeming to be traced or at least not getting its members relocated if a profile in the icc manager was relocated. This fixes the breaking of the psdcmyk device in rev 11499. Also removal of spurious warning messages.

Improve Ghostscript operation when current directory is not included in the search path. 1. Make file path separators at the end of LIBPATH entries optional to reduce the number of trivial configuration errors. 2. Search LIBPATH list for valid iccprofiles/ directory as a sibling to (Resource) and set it as a default to ensure a valid default. This code follows /GenericResourceDir example. 3. Make sure that the path name derived from /GenericFontDir is is not searched but other font file names are searched. Earlier code relied on a feature of .libfile not searching for an absolute path and failed when the path was relative. Partial fix for bugs 691350, 691408.

Improve Windows batch files. Bug #691440 "Windows bat files use relative paths and write to non-temp dir" As suggested by Bjorn Martensson in bug #691440. Altered all batch files which call other batch files so that they prepend the call with the location the original batch file was executed from. This allows batch files such as ps2pdf.bat to be called from locations other than the Ghostscript 'lib' directory. Also altered the location of temporary files created by the batch files to the Windows temporary folder by using the %TEMP% environment variable. If this variable is not set for some reason then this will still default to the current directory, as it does now. This allows batch files to be run from directories which are read only. Since these files are not used by our (Linux) cluster there will be no differences. I have tested a number of the scripts, but not all of them. The ones I have tested seem to work well. I finally found a reference which states that the %~d batch parameter was introduced to Windows in NT4, this means that these batch files will likely fail on older versions of Windows (ie Windows 3.x/95/98). I don't believe we need to support such antiquated Operating Systems any further.

Extend the experimental ENABLE_TRAP_AMALGAMATION code to the TEMPLATE_slant_into_trapezoids cases too. The current code generates 3 trapezoids; the new code will (if the option is enabled) attempt to amalgamate the top/bottom traps into the middle one. Enabling this code (but disabling the existing code for trap amalgamation) shows no differences. Enabling all the trap amalgamation code shows 888 differences, all fairly innocuous. As this code is going in disabled, no cluster differences are expected.

Fix : temporary memory device not finalized. clist_init_data creates a temporary memory device in order to "get the memory planarity set up", using a local variable to hold the device. When the function exits the variable goes out of scope and disappears. Because the memory device is a forwarding device it increments the reference count of its target, but because it is never finalized it does not decrement the reference count when it is destroyed, leading to an incorrect target reference count. This only affects pdfwrite at present, but it prevents valid PDF files being written because the file is only terminated when the pdfwrite device reference count reaches 0 and the pdfwrite device is closed. Added calls to finalize the device before discarding it. No expected differences.

Fix (pdfwrite) : Named destinations with no /Page not working properly Bug #691344 "REGRESSION: ps2pdf of 8.70 generates correct hyperlinks but not ps2pdf of 8.71" The revisions 9779 and 9788 fixed a problem where DOCVIEW pdfmarks without a /Page or /View entry were producing invalid PDF files, and a problem with DEST pdfmarks arising from it. Because DOCVIEW and DEST pdfmarks share some common code in pdfwrite to create a Destination annotation in the outptu PDF, this still left some confusion in the code. The problem was that DOCVIEW pdfmarks need not contain Page or View data, but named destinations *must*, but pdfmarks need not specify, in which case the current page is used. Added a parameter to pdf_make_dest which allows us to differentiate the two cases and use the current page number for a named destination if no page is supplied.

Enhancement (pdfwrite) : Fall back to Flate instead of JPEG when an image turns out short. Bug #691435 "any PDFSETTINGS besides /default gives dictfull error" There are two problems; firstly when an error is encountered closing a filter the error code (-1 or -2 usually) is returned and interpreted as a regular GS error, resulting in ridiculous error messages. Modified to return ioerror instead. Secondly, when an image terminates with insufficient data and pdfwrite is creating a DCT encoded image, we can't complete the image. In this case try to fall back to the simple Flate compressed stream instead. No differences expected.

Fix for Bug 691431. This was caused by a PS CIE color space being used for a transparency group color space. That really should not be allowed since those color spaces are unidirectional. They are installed though when -dUseCIEColor is used with a PDF file that has transparency. Solution is to use the default ICC profiles for the group color space when this occurs.

gx_device_has_color() was changed 8 years ago in the deviceN commit (r2925), from just color_info.numcomponents > 1 to || (dev)->color_info.gray_index == GX_CINFO_COMP_NO_INDEX . This has some unfortunate side-effect for continuous tone gray devices which doesn't support transparency, such as a 8-bit gray X11 display, which goes down the wrong code path. These are quite rare so it took 7 years for the bug (bug 690428) to be seen.

Provide more robust behaviour when FT fails to render a glyph. Inistead of silently continuing when FT errors on a glyph, we'll now attempt to use the notdef, if the notdef triggers an error, we signal the error to the GS world. This ensures that any time we expect processing to continue there is valid glyph information available to the cache and other downstream devices. This causes one regression difference with 34_all.PS, where an extra TTF notdef is rendered. Bug 691416

This patch adds limited support for TrueType collection fonts to pdfwrite and ps2write. In the PostScript world TTC fonts are never passed down to pdfwrite, we only ever see TrueType fonts. XPS, however, can pass back TrueType collection SNFTS data. This patch uses the first font from the TrueType collection and writes that to the output file. This may be too limited and may require further work in future.

Fix for 691359. Problem tracked down by Alex. What lcms is trying to do is to figure out the best prelinearization for the incoming data prior to doing the CLUT interpolation. In the case when the input is RGB based and the output Gray, lcms was using uninitialized data in constructing is prelinearization. Tangentially related, there could still be problems with what lcms is doing here if the number of Input channels is 1 and the number of Output channels is 3. In that case, it is possible (but not likely) that I could have radically different gamma behavior in each of the RGB channels. Trans in such a case would be constructed based upon only one curve based on the red channel. In the real world, this is probably not a problem but ideally it would be optimal to use something that provides the best prelinearization in all three channels. That is an optimization for Marti to do and perhaps is already in lcms2.

Erase patterns with the color white instead of filling the pattern bitmap with 0 or 255. Previously the initialization was only used when anti aliasing was enabled, now initial erasing is done for all colored patterns, eliminating a long standing UMR in the pcl code where the pattern was combined with the destination/source with indeterminate results. The UMR manifested in frequent regression reports in the pcl tests (c321.bin for example), these reports should go away with this change, though (NB) the change only masks the underlying issue.

Fix (pdfwrite) : limit composite object sizes when producing PDF/A Bug #691370 "Dictionary size not limited for PDF/A-1" The PDF/A specification insists that the implementation limitations of Acrobat as defined in PDF 1.4 should be followed when producing PDF/A files. Accordingly this limits the size of dictionaries to 4095 and arrays to 8191 when producing PDF/A output. Since there is no way to ignore the problem, setting the PDFACompatibiltyPolicy to 1 'don't emit the object, carry on producing PDF/A' can't be made to work. Since the user has expressed a desire for an output file, we fall back to Policy 0 'Produce a regular PDF file' instead. Also extend PDFACompatibilityPolicy to include policy 2 'abort'. No test file for this case, no differences expected.

Fix (pdfwrite) : Don't emit invalid PDF/A files Bug #691383 "pdfwrite emits invalid PDF/A when glyphs are missing in the input font." If the input file references glyphs which are not in the font, then we could emit a PDF/A file which also referenced glyph which were not present in the fonts embedded in the PDF file. This patch uses the PDFACompatibilityPolicy to control the action in this case, and avoid emitting invalid PDF/A files. Also extended the functionality of the PDFACompatibilityPolicy to allow the user to abort PDF file production when a valid PDF/A file cannot be produced. No expected differences as PDF/A production is not tested by regression code.

Fix pdfwrite - device reference counting problem with patterns and XPS When using XPS as the input PDL, and pdfwrite as the output device, the pdfwrite device was counted up by pattern accumulator allocation, but the clist accumulator never counted the device down, leading to a reference count > 1 at EOJ. This meant that the pdfwrite device wasn't closed, since pdfwrite only emits the PDF file when it is closed this led to invalid unfinished PDF files. The code here modifies the behaviour of the pattern management so that we don't use the 'clist' path for accumulating patterns *if* the device can accumulate patterns itself *and* the PDL doesn't have_pattern_streams (to avoid pathological PDF file problems) This resolves the issue with device reference counts and all the FTS XPS files now produce complete PDF files.

Fix for Bug 691368. lcms appears not to check its handles of link transforms when a profile is released, to clear out xform->InputProfile. Probably due to the fact that lcms may not expect a change of the formatters after the link is created. That would imply that we would need to create links based upon data types, which is not so efficient. Disable this check in lcms since it is only related to named color profiles, which we will not run into. Will kick this up to Marti.

Fix pdfwrite, faulty matrix transformations for Shading dictionaries Bug #691352 "cairo pdf mis-distilled" Patterns in PDF are unpleasantly complicated by the need to transform the pattern to the 'default co-ordinate space'. Normally this means that we undo the resolution scaling which is normally applied to the CTM. For page streams this works well, but for forms the 'default co-ordinate space' is the space of the parent. For one level of form there is therefore no difference between the page and the form. When forms are nested however, the lower form's space becomes that of the parent. This means that patterns inside forms, which are nested inside another form, need to be transformed to the parent form co-ordinate space, not the page space. Since we don't currently emit forms from pdfwrite for anything except transparency groups what this means in practice is that we don't undo the CTM transformation if we are rendering a pattern inside a form, nested inside at least one other form.

This occurs when using separation device with a limited set of colorants invoked via a command like -c "<< /SeparationColorNames [ /Cyan /Magenta /Yellow /Black ] /SeparationOrder [ /Cyan /Magenta /Yellow /Black ] >> setpagedevice"

Removal of iccprofiles/ from default icc profile names and post-pend %rom% with iccprofiles/ . This is in preparation for having the ps init code initialize a default value for ICCProfilesDir (which will be ./iccprofiles/ ) so that code works with COMPILE_INITS=0 when not in the base directory and when -sICCProfilesDir is not specified on the command line.

Fix copy CIDFontType 2 properly Bug #690930 "Unicode Output: DEVICE=pdfwrite" When making a copy of a CIDFont with TrueType outlines (CIDFontType 2) for the benefit of pdfwrite, do not simply copy the subst_CID_on_WMode structure member as this will be restored away along with the font at end of page. Instead make a new structure and store that in the copied font. No differences expected, local cluster test shows a few but I think (hope) these are related to the ICC branch merge.

Merge of icc_work branch into trunk. These changes make the color architecture of the graphics library ICC-based. All colors are now managed in terms of ICC profiles including PS CIE color spaces, for which equivalent ICC profiles are created. A big feature of this change is that it makes it very easy to interface a color management module (CMM) to ghostscript. The default CMM is now littleCMS and the interface to littleCMS is contained in gsicc_littlecms.c . New member variables were added to the imager state including an ICC manager, which stores the default ICC profiles; a link cache, which reduces the cost of creating links between ICC profiles, and a profile cache which stores color spaces created from PS CIE, PDF CalRGB and PDF CalGray colors spaces. A new directory named iccprofiles has been added. It contains the default ICC profiles used if none are specified in the command line. If COMPILE_INITS=1, these will be included in the ROM file system. The new command line options related to ICC profiles are described in the Use.htm documentation. For c-list based rendering, all ICC profiles used in the rendering are stored in the c-list. During multi-threaded c-list reading, a link cache is associated with the primary reader device and is shared amongst the various threads. Efficiency improvements were made in the handling of soft mask groups, shading smoothness calculations, and color image rendering. For details on the branch, please see the commits that were made within the branch. There remain indeterminisms to fix. The files affected include Bug688807.pdf, Bug688845.eps, Bug690208.pdf, 09-34.PS, CATX0988.pdf, CATX1028.pdf, CATX1101.pdf, CATX5529.pdf. Rendering issues to investigate include Bug689830.pdf, fts43xx.xps (page 3) (shopping cart image), Bug689880.pdf, Bug691002.pdf, Bug689968.pdf, Bug688584.ps (page 4), catx4949.pdf. Note that the number of differences generated with the merge amounts to pretty much every file. Thanks to everyone who helped and provided input in this work, especially Ray Johnston.

Following Acrobat implementation but contrary to TTF spec, consider cmap entry that has endCode < startCode as an entry with endCode == startCode. According to the spec, "to use these arrays, it is necessary to search for the first endCode that is greater than or equal to the character code to be mapped. If the corresponding startCode is less than or equal to the character code ...". I.e. an entry with endCode < startCode should have no effect. Thanks to Ken for the patch. Bug 691326.

Fix: device reference counting problem with patterns and clipping Bug #690572 more details here. The problem was caused by installing a clip device while drawing a pattern tile. This patch initialises the finalize member of the structure where the clip device will be created to NULL. If a clip device is required, the member will be initialised to a real routine. After drawing the pattern cell, if the finalize routine is non-NULL we execute it. This correctly dereferences the forwarded device if we create a clipping device.

Some work towards (but not a complete cure for) bug 691030. Previously XXX_slant_into_trapezoids would check for 2 'simple' cases, and bale into the fully general fill_slant_adjust function otherwise. The simple cases were where the top span was a subset of the bottom one, or vice versa. Unfortunately the way the code to test for these cases was originally written, one of these special cases could be used for shaped with vertical sides, and the other couldn't. By rewriting the test slightly, both cases can be used with trapezoids that have one vertical side. For good measure we also extract the 'rectangle' case out separately. Cluster testing shows no differences (barring a couple of indeterminisms). This reduces the output from 5 shapes (2 rectangles, 3 traps) to 3 (2 rectangles, 1 trap). One of the rectangles is still a repeat, but it's a step in the right direction.

Fix - type 1/CFF font interpreter. The gs_type1_piece_codes routine interprets a type 1 or CFF glyph program to determine whether the glyph is composed of two subglyphs (a SEAC). There was a problem with the CFF opcode cntrmask which did not cater for the case where it is called with a number of operands on the stack. In this case the operands are to be interpreted as vstem hints. Because this was not done, the interpreter had the wrong number of hints, and so did not interpret enough of the following bytes as mask data for the cntrmask operation. This led to attempting to interpret data as operands, which caused corrupted glyphs as well as potential crashes. This does not appear to be tested by any of our current test files (according to a cluster test), so no differences are expected.

Fixes portability issue properly with r11256 (which is identical with r11520), first discovered by Ralph 6 months ago with r10520 which results in its being reverted in r10540 . ****************************** Revert c10520 which causes problems with the MSVC build. $(CC_) enforces 'ansi' C under msvc32.mak, disabling any Microsoft extensions. This often causes problems with 3rd party libraries which try to take advantage of those extensions. This means that the -fPIC flag is again not propagated in the GCC build; this is just to unbreak the build until I can test a different solution which works on both platforms. ****************************** As Ralph explained then, some of libtiff requires non-ansi extensions to work. The main culpit is tif_win32.c (which includes <windows.h>) and some of the file IO flags not being defined. So this commit fix the ansi issue properly.

fix windows build breakage in r11249 This change (defining TIFFCONFIG_SUFFIX) should have been part of r11249 (create tif_config.h for non-autoconf build) which in turn should have been part of r11241 (hook up libtiff with non-autoconf build via "make -f base/unix-gcc.mak" and "make -f base/unixansi.mak") The explanation is that in r10317 where Lars originally hooked up libtiff, tif_config.h is generated by libtiff/configure (which is driven by the top-level configure), but special provision is provided for non-autoconf build (win32 and VMS) by copying from a canned header file. If one chooses to bypass the top-level configure, *on every platform* (win32, VMS, and non-autoconf unix build), one must provide similiar special provision as well. Personally I'll prefer not to support non-autoconf unix build.

Add skeleton support for the Bitstream font engine. In its current form this only allows for type 1 PostScritp fonts, CFF is trivial to add, as should be support for Bitstream's own compressed format. Addition of type 42/TrueType fonts should be patterned after FreeType, as there is support in Bitstream for a callback to provide TrueType outlines. There is no such provision for PostScript fonts. To build; define BITSTREAM_BRIDGE=1 and BITSTREAM_ROOT="", the root should point one level above the 'core' directory. In the current code this would be : "/bitstream/FontFusion 4.5a SDK"

The final part of trying to "ln -s base/unix-gcc.mak Makefile ; make so" work. There were some fundamental problems with the older version: The so target really should be built in three distinct stages with three different FLAGS - the utils (genarch, gechogs) executable part, the shared library part, and the two final executable part. The library should be built with the shared-object flags, but neither of the utils nor the final executables should be built with "-shared", since they are executables and not libraries. Hope this is clear. There is also a little problem from SOC_LOADER not being defined if this file is not used from ./configure's Makefile.

Fix FAPI interface There is code in the FAPI interface for replacing a font's /FontBBox entry, this sometimes has to create a new array to insert into the dictionary, if the old array is not suitable for storing real values. The code to do this continued using ref_assign_old, as it had done for replacing the values in an existing array. This appears to be incorrect, when created the refs in a new array are uninitialised so attempting to use ref_assign_old tries to use uninitialised data. Modified to use ref_assign_new instead, as indicated by the comments in store.h This *may* reduce some of the non-deterministic behaviour, possibly with files such as ShadowText.eps

Fix (FAPI) The PDF interpreter, when a font is missing, and it has the 'small caps' flag set, creates a substitute by altering the CharStrings of the substitute font, replacing the lower case glyph CharStrings with procedures which 'show' the upper case glyph at a reduced size. This ends up in the FAPI code as a t_mixedarray type which was being missed by the check for a t_array, added previously to handle arbitrary procedures in a type 1 font. After extending the check to include t_mixedarray it was clear that the SEAC processing was also messing up the dictionary lookup, so it was necessary to restore a value which had been overwritten in case a SEAC turned up. zero-length-font.pdf should now work as it does without FAPI, no other differences expected.

Fix (FreeType) : illegal use of setcurrentpoint not handled as per Adobe. Bug #691172, file type1-ce1_setcurrentpoint.ps The PostScript file includes a font which illegally uses setcurrentpoint to establish an absolute x/y position. The spec is quite clear that this operator is *only* meaningful when processing the results of an OtherSubr, so this usage is definitely illegal. Not only does it use setcurrentpoint but, unlike previous uses we have seen, it does not simply establish 0,0 as the initial point, which can be safely ignored, it actually uses it to displace the outline vertically. FreeType normally just puts two uninitialised variables on the stack, ignores the setcurrentpoint and pops the two dummy values. Instead, we now push the current x and y co-ordinates when we get a '0 callothersubr'. In setcurrentpoint we then use the top two values on the stack to set the current point.

Retry of fix for Bug 69048 (this one actually builds...) Again this should only be a factor when using GraphicsAlphaBits. The fix was to make sure that when GraphicsAlphaBits is used we initialize the pattern bits buffer. Otherwise the get_bits operation used during the gx_default_copy_alpha grabs uninitialized memory. Since we do not test with GraphicsAlphabits in the regression testing I don't expect there to be any differences.

Fix (FAPI & FreeType) Bug #691284 "Error: /unknownerror in --.FAPIBuildChar" The issue is caused because the PostScript file adds to an existing type 1 font a CharString entry which is not in type 1 CharString format. I would have thought this to be illegal but other PostScript interpreters (specifically Distiller) are happy with it. Modifed the FAPI interface so that after retrieving a type 1, non-CID, CharString we test to see if it is a procedure, if it is, then we return an error from the FAPI code to the caller (in this case the FreeType interface). Modified the FreeType interface so that if the CharString retrieval returns an error we return a specific (otherwise unused) error to the caller, in this case the FreeType engine. On return from FreeType to the interface we test for the specific FreeType error (FT_ERR_Invalid_File_Format) and if this is detected then instead of returning an error to FAPI, we add one to the character index (to ensure it isn't 0) and return that to FAPI. Finally, in the FAPI code, after 'rendering' the glyph, if we were returned a value > 0 then we assume that 'something went wrong' with the CharString. As a last-ditch effort we use the return value -1 to retrieve the CharString, and then 'exec' it. NB if we fail to retrieve the CharString at this level, we return an invalidfont error.

More work towards bug 691207 (global variable removal). There are 4 places is xps where we do eprintfs that access mem_err_print. This resolves 1, the other 3 should never be called in files we support. Resolve 4 const warnings from jasper. Remove 2 calls to gs_lib_ctx_get_non_gc_memory_t from the cups driver. This means the only places left calling this are devices in gs\contrib. Convert calls to errprint_nomem to calls to errprint (in gdevx.c, gxttb.c, gdevupd.c) The only places using mem_err_print are therefore: * calls to debug printing functions * devices in gs/contrib calling gs_lib_gtx_get_non_gc_memory, errprint_nomem, and eprintf. * jasper calling eprintf. * gdevsco.c (but that seems intrinsically single threaded to me as only one thing can be using the console at a time, presumably) * signal handlers in os2 and iwatc for catching numeric exceptions. * Various devices in gs/base still call errprintf_nomem - some in DEBUG only code, but some not. * The gs_throw_imp function. I think this may be as good as we can get at this point. No differences expected, or shown by local cluster testing.

As part of the work for bug 691207 (remove global variables) we introduce a new set of macros, "emprintfX". These do the same as the "eprintfX" macros, except they take an explicit memory reference rather than using the mem_err_print global.

As part of the efforts towards bug 691207 (global variables must be removed) this commit reduces the reliance on mem_err_print. Currently all calls to errwrite and errflush get the stdin/out/err details from a global mem_err_print. For multithreaded gs this will result in output going to the wrong place if any of them are redirected. This review splits errwrite into 2 variants, errwrite and errwrite_nomem. The first takes an explicit mem pointer. The second continues to assume a global one. The plan is to make everything possible use the first. Currently debugging calls and some 'stubborn' devices continue to call errwrite_nomem. Local cluster testing shows no differences.

Fix (pdfwrite) incorrect ToUnicode CMap. Bug #691274 "Missing or incorrect ToUnicode when using Identity ordering" pdfwrite emits ToUnicode CMaps in PDF files which always use 2 bytes for the key length. That is 0x21 is represented as <0021>, since these are hex strings there should in fact be no difference between <21> and <0021>. It is clear from the ToUnicode Mapping file tutorial that this is correct for mapping files. However, a PDF file is not a CMap file. It appears that Acrobat does not like beginbfrange data which is padded with zeros (it seems happy with codespacerange and destination codes which are 0 padded though). This patch outputs ToUnicode CMaps which are not padded with 0, ie 0x21 is emitted as <0021>, for the srcCodeLo and SrcCodeHi parameters in a beginbfrange operation. The destination codes remain zero-padded. Technically this would be incorrect for a real CMap file, but we don't write those out so this should not be an issue. The change is limited to ToUnicode CMaps and does not affect any other kind of CMap. I believe the change will affect the data emitted for the beginbfrange, beginbfchar, begincidchar, beginnotdefchar, beginnotdefrange and begincidrange operators. It does *not* affect the begincodespacerange operator; although Acrobat Distiller writes this without zero padding tests show that Acrobat is happy reading zero-padded code space ranges. ToUnicode information is not used in rendering PDF files, so regression testing should show no differences. Local testing of a limited number of files doesn't reveal any problems, but this change has not been well tested.

Modify the 'C' defaults of the pdfwrite device Bug #691259 "HPGL graphic followed by raster graphic results in incorrect pdf" The pdfwrite device is initialised in 'C', and then partly overridden by PostScript initialisation. The problem is that non-PostScript input does not (cannot) execute the PostScript initialisation, and so the defaults are left as those done in 'C'. Not only do these defaults not match the documented defaults in ps2pdf.htm, they are not particularly well selected. In this case the problem was caused by sending image data at 150 dpi, but only a single scan line at a time. The default setting for pdfwrite was to downsample image data to 72 dpi, this caused us to subsample (the default downsampling) by a factor of more than 2, which led to our single scan line becoming less than half a scan line, and so disappearing altogether. This patch addresses this issue by altering a number of the defaults to more sensible values. In particular we disable downsampling and enable image compression for gray and colour images. This has the fortunate result of making most PDF output files smaller than before, even though we are now storing more image data.

Move op_array_table_global and op_array_table_local away from being globals and into i_ctx_p. This requires various knock on changes throughout the code to enable them to be recovered from the context (which may itself need to be recovered from a memory pointer). Also, the garbage collection is altered slightly; rather than the op_arrays being special cased (as special objects that have to have their component parts registered as roots for the garbage collection) we move them inline into i_ctx_t and amend the gc routines for that structure. Thanks to Alex for his help with this. No differences expected, or shown with local cluster testing.

Change so that when a graphic state is restored, the overprint compositor action only occurs if there is a change from the current overprint state. This fixes a problem in one of the files associated with bug 691014. In the particular file, overprint compositor actions were getting placed into a pattern clist. The file in fact had no overprint settings. Ran regression test, no differences expected.

Fix for Bug 691014. Problem was caused by the fact that we had a soft mask present and a pattern with no transparency. This means the PDF14 device is installed and more importantly that transparency state pushes and pops occur to keep the softmask in sync with the graphic state. This particular files pattern is installed as a clist, which happens to not have any transparency. The transparency state pushes and pops were getting placed into the pattern clist when the Q and q operations occurred in the pattern, which was causing problems since the pattern clist device had no pdf14 device installed to handle such commands. The solution is to check, when a transparency compositor action is to occur, if the current device is a pattern accumulator or a pattern-clist device. If it is, then the pattern instance is checked to see if it has transparency. If it does not, then the transparency state chance is ignored. This all occurs on the clist writing phase in the gs_trans functions. In addition, a fix was made so that the pdf14custom device sets up it's color information correctly. For subtractive devices that do not have cmyk process colorants the custompdf14 device is installed. This pdf14 device was obtaining its color_info from the target device. The pdf14 device must be continuous tone even if the target device is not. Ran a regression test and saw no differences.

Fix for a problem in the rinkj driver for Epson Stylus Photo 2200. The code was accessing indexes 4,5,6 in plane_offsets[6] and hence was running off the end of the array. This was causing a warning at compile time but never caused a segv as it was merely corrupting the next entry in the structure which was reset to 0 shortly afterwards. Presumably the offset for one of the planes would be wrong though causing a loss of quality.

Remove several occurrences of calls to gs_lib_ctx_get_non_gc_memory_t(). The only code that now needs this is gp_macpoll.c and gp_mspol.c for when CHECK_INTERRUPTS is defined. This reduces the need for mem_err_print. The only other code that uses mem_err_print is errflush() and errwrite(). Potentially these could be nobbled for a multithreaded build. The changes here rely on the memory pointers being set up correctly. While local cluster testing gives this a clean bill of health, it's possible that problems will appear with files in the wider world - we'll just have to fix these as they are reported.

Move CPSI_mode from being a global to living in the libctx, as part of the efforts for bug 691207 (remove global variables). I originally tried moving CPSI_mode into the imager state, which would have been slightly nicer, but had to abandon this due to problems interacting with the command list code. My first thought to make this work was to push the value of CPSI_mode into the clist at initial clist creation time. As the setting of CPSI_mode isn't vectored through the device, we can't detect changes in its setting, but then changing CPSI_mode during the lifespan of a clist would give unpredictable results anyway in many cases. Sadly this was doomed to failure as if a page device is started up that uses the clist code to do banding, then the command list is created before CPSI_mode is enabled, and we'd operate with the incorrect value. Moving CPSI_mode into libctx means we keep exactly the same behaviour as we have now. This has required various functions throughout the code to pass a gs_memory_t * around. Localcluster testing reveals no problems.

Fix for bug 691244, reported/patch supplied by Norbert Janssen. In revision 11045, I'd moved some globals into the libctx, which is accessed via the gs_memory_t pointer. This has required certain functions to now take a gs_memory_t pointer as an extra arg. In this particular case the gs_memory_t pointer in question could be NULL. The fix is to use one obtained from gs_lib_ctx_get_non_gc_memory_t, a call to which happens conveniently to be on the previous line. gs_lib_ctx_get_non_gs_memory_t is going to be painful to remove later on, but at least this fix gets us up and running again now.

Update the clist band list compressor code to work without using global variables as part of the workd for bug 691207 (remove global variables). The old code used to call a function to read an initialise global structure, then based on that allocate storage and copy the structure into it. The new code essentially does 2 calls; one that serves to get the size, and another that serves to initialise the newly allocated structure. To facilitate testing, this introduces a new TEST_BAND_LIST_COMPRESSION define. If built with this as a define, the code sets the compression threshold to 1K, thus forcing the use of compression. A local cluster push with this in reveals just one problem, and that seems to be in the existing code whereby inflateEnd can be incorectly called on a NULL derived pointer. A fix for that is included too. No expected differences.

Fix FreeType FAPI No bug for this (probably should be). Noticed while testing that using a TrueType to replace a missing CIDFont (ie entry in cidfmap) was rendering the wrong glyphs, and applying a vertical advance. The incorrect glyph seems to be because we were incorrectly stating that the character index was not a glyph ID, which it is in this case. The second problem was more difficult. FreeType manufactures vertical advance metrics for all TrueType glyphs, we override those in the incremental interface callback, but when the TT is a CIDFont on disk, we don't use the incremental interface and so have no opportunity to override the metric. Addressed this by checking in load_glyph to see if the current font is not type 1 (ie its TT), *is* a CIDFont, and is not a vertical font (WMode is 0). In this case we simply override the vertical advance and maek it 0.

Fix TrueType interpreter Bug #691227 Another nasty hack for another broken TrueType font. In this case the font tries to execute a DeltaP instruction with an argument greater than the number of points in the glyph, which is an error. FreeType's interpreter has this comment /* XXX: Because some popular fonts contain some invalid DeltaP */ /* instructions, we simply ignore them when the stacked */ /* point reference is off limit, rather than returning an */ /* error. As a delta instruction doesn't change a glyph */ /* in great ways, this shouldn't be a problem. */ This patch more or less mimics this in our code.

Remove the commented out invocations of autoheader and aclocal/automake in the autotools bootstrap script. The various autotools modules must be invoked in a specific order, and usually with non-default options. We only use autoconf in our build, not any of the other tools which layer on top of it, but I had left their invocations in the script, but commented out, so make it easier to add them at a later date. It's been some years since autogen.sh was added, and we still have no plans to adopt automake. Also, the script didn't include support for libtoolize (which is glibtoolize of MacOS X) nor for detecting the appropriate automake version, so it seems simpler to just remove the commented out lines to avoid confusion.

Remove the function scope static variables from gdevcdj.c as part of the efforts for bug 691207 (multithreaded safety). These only affect the ESC/P driver. There are 4 variables in play here. real_rows doesn't actually need to be static at all as it is always set before being used. The other 3 (ln_idx, vskip1 and vskip2) all go into the 'ep_globals' structure. There is a subtle change in behaviour here; previously these variables were initialised to zero on execution start (and again on every flush). Now they are initialised to zero at the start of every page (and again on every flush). This means that leftover vskips are no longer carried forwards from page to page. This seems like a good thing to me.

Remove global variables in gdevcdj.c as part of the effort for bug 691207. The ESC/P based printing code in gdevcdj.c uses various global variables; we gather them into a struct here, and pass the struct between the 2 functions concerned. This device isn't used in the default build, so no point in testing with the localcluster. Enabling it locally and doing before/after tests shows that identical results are given for rendering tiger.eps. A side effect of this commit is to remove the nasty shadowing of the img_rows variable (doubly nasty because of it's use within a macro). This meant that I had the code wrong for a while, so I know the test is actually testing the right thing.

Fix for bug 691228, problems with wide strokes with round caps/joins with antialiasing enabled. 2 small problems in the same code. In the antialiased case, we stroke by forming 2 paths (one up either side of the line) and then reverse one and concatenate it. This should happen whenever we meet a closepath, but due to a misplaced return, was being missed out in some round join cases. Also, when using a round join in the case where 2 lines meet 'in-line' we would inadvertently leave the point on the wrong side of the line. No changes in localcluster testing as this only affects antialiased results and that's not tested currently.

Fix FAPI and FreeType interface. The Metrics override was broken, the code to retrieve the /Metrics entries (1 to 4 values) stored the results in an array in a different order to the code which read the values back. In addition the FreeType code did not reset the 'glyph_metrics_index' if a glyph had no metrics override, which could lead to us using the metrics overrides from a prior glyph if we had already encountered one using an override.

Fix FreeType When using bitmaps from a TrueType/Type42 font FreeType uses a heuristic approach to synthesize vertical metrics for the glyphs, including a horizontal advance. As in the past, this works well as long as the client knows whether the advance direction is horizontal or vertical and uses the correct advance. However we don't know that, so we don't want the vertical advance. Its easiest jut to have FreeType ignore embedded bitmaps and use the outlines, in which case we don't get the invented vertical advance. Not only that but the rendered bitmap is a better match for the cases where we don't have a pre-built bitmap, so consistency is improved with this patch as well.

Fix FreeType The test file objlune_font2_mine.ps contains a Type 1 font which has a technically invalid glyph. The glyph executes a 'lineto' class operation before a 'moveto' class operation.

'Fix' FAPI with FreeType. FreeType's hinting is worse than useless for type 1 fonts, its actually harmful. It distorts the glyph shape because it hints an unscaled outline. While it would be best to fix FreeType's hinting this is a large project. For now this patch disables FreeType hinting when handling type 1 fonts. This resolves many spacing issues as well as fixing the stroke/fill mismatch with ia3z3519.pdf and the incorrectly scaled outline in womanface.pdf.

In the gs_2_colors branch I had made 2 copies of the color state and swapped between them. I had included dev_ht as part of this 'split' state, which was a significant contributor to the slowdown due to it forcing repeated writing of the halftone data to the clist. Also, it required significant extra work on every setscreen or setcolorscreen operation. Discussions with Henry/Ray/Kens et al lead to the realisation this wasn't required. This patch therefore backs out the dev_ht split, and the changes to zsetscreen and zsetcolorscreen. Additional code is however required to clear the 'alternative' dev_color when a halftone is installed to stop the 'swapped out' color pointing to an illegal halftone cache. This runs through local testing with no diffs showing (though some strangeness was observed with an earlier version of this patch in regression testing - Marcos has captured this with bug 691223). This seems to have helped with the largest slowdowns, but there are still significant differences in some cases. Very preliminary investigations seem to show more time being spent in the interpreter/gc mechanism. Continuing to investigate.

New Fontmap files for the URW fonts, both type 1 and TrueType formats. The file Fontmap.URW-136.T1 contains definitions for the type 1 fonts (the URW PFB fonts must be in the search path).

Currently neither of these work 100% because of problems with the URW font sets (several incorrectly named fonts, and in one case an illegal type 1 font)

Fix for bug 691115. In some circumstances, the shading code can get all the way to the point of marking the screen/page without ever clipping to the relavent region. This produces cases where we "draw outside the lines". Often this is masked by the fact that we only ever draw as far out of the lines as would be covered by an area of constant color (typically a small area). The fix for this is to spot the unclipped case when we come to render trapezoids to the screen, and to clip the trapezoid into (at most) 3 smaller trapezoids. This causes 104 non-pdfwrite differences, and 24 pdfwrite ones. Examination using localcuster bmpcmp shows them all to be acceptable.

Compute AES cypher tables at compile time instead of run time. The aes implementation needs some tables of data to perform its calculations. In a thread-safety review, Henry spotted that the tables were global variables with no mutex isolation. I believe this is actually ok. There is a static flag marking whether the tables are initialized. If they are not, a call to aes_setkey_* will invoke aes_gen_tables to initialize them, then set the flag. However, aes_gen_tables operates deterministically, always writing the same data sequence to the globals. So while there is a race where two threads could be executing aes_gen_tables at the same time, or while another thread is accessing the same tables, there is no read-modify-write step which could create inconsistent data. Nevertheless, the tables are small relative to our application, and there is a compile time option XYSSL_AES_ROM_TABLES which generates the data at compile time and stores it static const. This commit turns on that option, allowing the compiler to put the data in a non-writable segment and making the careful thread safety analysis above unnecessary. There should be no difference in behaviour, and Henry has verified that the two code paths result in identical table data.

Update the list of face substitutions in .substitutefaces to include all the fonts we define in Fontmap.GS (if not already defined). Bug #691180, if we have a font defined in the Fontmap then we don't use the additional information in a PDF file FontDescriptor. Instead we stick with whatever font the PS substitution comes up with (if the font is not present). If a member of the family is not defined we do use the FontDescriptor. This can lead to different choices for the substitute font. By defining the font in the substitutefaces array we can attempt to get a consistent result. This *will* lead to differences in the regression suite as we are now substituting different fonts for some missing faces. Apparently only with the test file for this bug though.

This adds a new set of color state information to the graphics/imager state, along with a new non-standard postscript operator .swapcolors to toggle between them.

This produces differences in just 2 pdfwrite tests, due to rounding errors due to changes in the way pdf with non-zero rendering modes is emitted now.

Change the condition under which we update the overprint device when restoring a graphics state to be more relaxed; rather than updating if the overprint state has changed we now update if it was enabled, or it if it is enabled. The logic behind this is that it will still fire in all the same conditions it did before, but will also fire when we restore from a state that had it enabled to another state that had it enabled. This should be entirely harmless, but will allow the state to be updated in the case where a colorspace has been updated. This causes 2 differences in the tests, that only show up in psd files. All indications seem to be that these files really are identical. But if they aren't, I believe they should be progressions, rather than regressions. This moves the trunk more into line with the output of the gs_2_colors branch.

Ongoing bug fixes for #690448. The FreeType code will synthesize vertical metrics for TrueType (Type 42) fonts which do not contain a vmtx table. This includes the vertical advance, which will be returned to the FAPI code, and used even if there were originally no vertical metrics and the font should not have any vertical advance. Modified the metrics override callback, called by FT, so that if the font is a TT font, and this is a vertical metrics call, we set the advance to 0. This prevents the synthesized metrics from incorrectly advancing the glyph vertically. This may eventually be a problem if we find a CIDFont with Type42 outlines which relies on the vmtx table in the font rather than the Metrics2 or CDevProc overrides to position the glyphs. Since this facility was only added in CPSI 3011 it is unlikely we will ever encounter such a font. THis has not been done at present, as the information (WMode=1) is not currently available to the code called from FreeType to override the metrics, and would need to be added. Also, fixed an issue where the 'advance_v' member of the metrics structure was left uninitialised if a horizontal override took place. This could cause glyphs to be mis-positioned vertically.

Fix FreeType Ongoing fixes for bug #690448. In this case FreeType generates vertical metrics for TrueType (in our case Type 42) fonts which lack vhea/vmtx tables, which is generally the case. These metrics are useful to a 'normal' TrueType consumer which has a notion of the orientation of the writing direction. However in PostScript we don;t know that, so we apply both the horizontal and vertical advance widths. If the vertical advance should be 0 (because its not specified) then creating one causes the glyphs to be misplaced. This code adds a new load flag to FreeType 'FT_LOAD_NO_SYNTHETIC_METRICS', and sets this flag in the FAPI FreeType interface code, which prevents FreeType from manufacturing a bogus vertical advance.

Add support to the autoconf and msvc builds to compile in a copy of the FreeType2 library from local source. Previously, the FAPI bridge for freetype required that the library be compiled externally and include and link flags passed through the FT_CFLAGS and FT_LIBS makefile variables. We now include a copy of the freetype source in the tree, to make it easier to find a compatible version of the source and to simplify building for platforms that don't provide a system freetype. Now, to enable both freetype and the FAPI bridge, pass --enable-freetype to the configure script. This will set FT_BRIDGE=1 and the other required variables. The configure script will prefer local source in gs/freetype2 to the copy in gs/freetype to simplify testing against upstream. To enable freetype in the msvc build, pass FT_BRIDGE=1 on the nmake command line. Note that the fallback is now FT_BRIDGE=0, not FT_BRIDGE undefined; this will require changes in any custom top-level makefiles.

Fixes bug #691147 customer 861, the optimization to strength reduce the raster operation here is wrong, it is premised on the assumption the colors are opaque. If either texture or source is transparent the strength reduction which effectively ignores the source or pattern is wrong and it will subsequently cause opaque painting.

Fix colour processing. It was possible for nested ICCBased colour spaces (ie an ICCBased space whose Alternate is another ICCBased space) to cause segmentation faults. This was due to the fact that the conversion to base colour continuation procedure 'currentbasecolor_cont' was supposed to scan the space from the initial declaration each time round a loop. However a reassignment of an array pointer caused it to rescan from the last processed colour array instead. Normally this does not cause problems, but in the case of nested ICCBased it caused us to generate an error. Fixed by re-initialising the array pointer at the start of the loop.

Firstly the undoing of PostScript string escapes was wrong, Octal escapes consumed too many characters, and several escape sequences weren't recognised. Secondly the XMP emission didn't expect to receive UTF-16BE strings and didn't convert them to UTF-8 for inclusion in the metadata.

If they include the UTF-16BE Byte Order Mark then convert the strings to UTF-8.
