5.15. Waves
5.15.1. Overview
图 17.95. Example for the Waves filter
Original image
Filter “Waves” applied with default options and period = 20.0
With this filter you get the same effect as a stone thrown in a quiet pond, giving concentric waves.
5.15.2. Activating the filter
You can find this filter through Filters → Distorts → Waves….
5.15.3. Options

These options are described in 第 2 节 “Common Features”. |
Center X, Center Y
Move the center of the waves
Amplitude
Varies the height of the waves.
Period
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.
Phase shift
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 插值.
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.
