Swirl
Swirl swirls the image centered at the specified coordinates and
up to a given maximum radius. The swirl starts from zero, increases to
full size in the first 1/3 of frames, remains at this size for
the next 1/3 and reduces to zero in the last 1/3 length of effect . Step
gives control of the fineness of the detail. The smaller the step the slower
is processing.
RGB, YUY2 and Planar 8/ 9-16/32 bit depth color formats are supported. Thread Safe.
