Nikolas List updated COCOON-2266:
---------------------------------
Attachment: imageop.patch
The following patch (partially) solves the two problems.
Two drawbacks for the solution of RotateOperation:
1) Will enlarge image for all angles not in 0, 90, 180, 270 (should probably
be controlled by allow-enlarge param ?)
2) Background is always black
> Result of RotateOperation/MirrorOperation is a black image
