It displaces the pixels of the active layer or selection to waves or ripples reminding a reflection on disturbed water.
The result of your settings will appear in the Preview without affecting the image until you click on .
This improves the scaled look the image borders may have.
This preserves the seamless properties if your image is a tile pattern.
That's the Horizontal or Vertical direction of waves.
Because ripples cause pixel displacement, some pixels may be missing on the image sides:
With Wrap, pixels going out one side will come back on the other side, replacing so the missing pixels.
With Smear, the adjacent pixels will spread out to replace the mixing pixels.
With Blank, the missing pixels will be replaced by black pixels, if the layer does not have an Alpha channel. If an Alpha channel exists in the layer, transparent pixels replace the missing pixels after applying this option.
Choose how the wave should look like:
Sawtooth
Sine
It is related to wavelength (0-200 pixels)
It is related to wave height (0-200 pixels).
It is angle to delay the wave (0-360 degree). Appling this filter again with the same setting but Phase shift differs by 180 brings the once processed image back to become almost similar to the first original image.
