Amplitude

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

  Amplitude = 25

Period

  It is related to wavelength (0-200 pixels)

  Period = 110

Phase shift

  Wave is moved

  Phase shift = 0.400

Angle

  Warps wave

  Angle = -40°

Resampling method

  These interpolation methods are described in Interpolation.

Wave type

  Choose how the wave should look like:

  - Sawtooth

  - Triangle

  - Sine

Abyss policy

  Because ripples cause pixel displacement, some pixels may be missing on the image sides:

  Abyss policy = Black

  Abyss policy (border management) is treated with Abyss policy.

Tileable

  This preserves the seamless properties if your image is a tile pattern.
