But otherwise, the behavior looks correct. You're so wrong! Please do the same with gimp. Gimp produces a really correct image. In LAB, the image generated by krita is completely wrong. Convert to an RGB 32bit float and do the same and you'll get the really correct image. Gimp does not require this step. This is because gimp always performs 32bit floating-point linear gamma internally. Remember to export as png for external viewing. The krita preview is also an error! -- You are receiving this mail because: You are watching all bug changes.
