--- Comment #2 from Szczepan Hołyszewski <rula...@wp.pl> --- Yes, I tried with semi-transparency and it was somewhat helpful but insufficient. It helps correct gross inaccuracies but doesn't help with very fine positioning of points. A 50% blend of original and unwarped scan looks about as good when the unwarping is pixel perfect as when it is two or three pixels off. However our brains are very good at motion detection, so if you could alternate between original and unwarped scan then you would clearly see features "jump", even blurry/blobby features that don't give enough feedback with semi-transparency. Maybe it could be possible to implement an additional hidding functionality independent of layer hiding? There is already a precedent where the layer being worked on with the transform tool is displayed differently: special blending modes get disabled (mode switches to normal). This means that there is likely a special code path for that. Couldn't that code path also override opacity to 0 depending on some UI in the transform tool settings? -- You are receiving this mail because: You are watching all bug changes.
