10.9.  Ripple

10.9.1.  Overview

This filter is found in Image>Filters/Distorts/Ripple...

It displaces the pixels of the active layer or selection to waves or ripples reminding a reflection on disturbed water.

10.9.2.  Options


The result of your settings will appear in the Preview without affecting the image until you click on OK.


Antialiasing: This improves the scaled look the image borders may have.

Retain Tileability

Retain Tileability: 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 Black, the mixing pixels will be replaced by black pixels.

Wave Type

These options are self-explanatory

  • Sawtooth

  • Sine


The Period is related to wavelength (0-200 pixels)


The Amplitude is related to wave height (0-200 pixels).
