Imagem original

Filter “Waves” applied with default options and period = 20.0

Com esse filtro você obtém o efeito de uma pedra jogada num lago tranquilo, gerando ondas concêntricas

Presets, “Input Type”, Clipping, Blending Options, Pré-visualização, Merge filter, Split view

  | Nota
  These options are described in Seção 2, “Common Features”.

Center X, Center Y

  Move the center of the waves

Amplitude

  Varies the height of the waves.

Período

  That is wavelength. Varies the distance between the top of waves.

  The high default value suits large images. For images of some hundreds pixels wide and high, a lower value, such as 20 in our example, fits better.

Deslocamento de fase

  This command shifts the top of the ripple.

Aspect ratio

  Values less than 1.00 render waves oval, with major axis vertical. Values higher than 1.00 give a major axis horizontal.

Resampling method

  These interpolation methods are described in Interpolação.

Clamp deformation

  This limits the deformation in the image area. When this is disabled you seem to get transparent or black areas (depending on whether the layer has an alpha channel or not). When enabled, these areas will keep their normal color.
