EffectRotation rotates the image part with given radius through given angle (-ve clock wise direction) Can be used to rotate scanned images or as an effect. The unaffected space of the frame can be painted with fill color or original image retained. The angle, coordinates of center, radius can be varied linearly during effect. RGB32, RGB24 and YV12 color formats only are supported at this time.

Details of parameters
Description Name Type Limits Default
clip clip none
Effect start frame number sf Integer within clip first frame
Effect end frame number ef Integer within clip last frame
Initial radius of image to be rotated ir integer 1 or more half of frame diagonal
initial angle of rotation in degrees id float -360 to 360 90
initial center x coordinate ix integer in frame mid width
initial center y coordinate iy integer in frame mid height
Fill color cc integer rrggbb format. If -1 then original image retained -1
final radius of image to be rotated fr integer 1 or more ir
final angle of rotation in degrees fd float -360 to 360 id
final center x coordinate fx integer in frame ix
final center y coordinate fy integer in frame iy
