Description

I encountered a bug with spot removal and crop and rotate tools. When an image is flipped (tested with horizontal flip) the spots in the spot removal tool are placed incorrectly. This happens only when adding new spots while the image is flipped. It is possible to fix spots on the unflipped image and then flip (spots stay in correct respective places). It is however not possible to add new spot removal on the flipped image due to offset.

The image was cropped and flipped.

Similarly, the gradient mask gets rotated in an opposite direction. Making me think there is a bug in the coordinate system on flipped images.

#2 Updated by Guenther Erhard 4 months ago

This bug is still present in 2.6 and it affects not only the spot removal but also the new retouch module.

If you flip an image horizontally OR vertically than the position of the spot is shifted and it is not possible to place new ones exactly.
If you flip an image horizontally AND vertically than the position of the spot is correct.

Interesting is that the position where spot removal or heal are applied is correct - only the marked spot are wrong. You can see this clearly when you enable "show mask" (see screenshot)
