EffectRipples
On the image in a pool area ripples are created. This is differently
formulated than EffectRipple,
and has a more pleasing liquid effect. The wave
speed, amplitude, pool area center and its dimensions can be selected
and also varied linearly. Ripples must always form from center of pool.
This restriction are for speed of rendering. Please see
EffectRipples2
for fewer restrictions, but may run slower.
RGB32, RGB24, YUY2 and YV12 formats are supported.
