Ripple applied with default options

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 methods

These interpolation methods are described in 插值.

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.

Use the selection as input, Use the entire layer as input
