Move the center of the waves
Varies the height of the waves.
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.
This command shifts the top of the ripple.
Values less than 1.00 render waves oval, with major axis vertical. Values higher than 1.00 give a major axis horizontal.
These interpolation methods are described in Interpolering.
TODO.
Dette filter kan resultere i et billede, som er større end det oprindelige. Med standardindstillingen for Justér vil lagets størrelse om nødvendigt automatisk blive ændret. Med indstillingen Klip vil resultatet blive klippet til lagets kanter.
