I'm sorry for a very long delay with the bug. But I still cannot see, what the problem is? If you set both masks' (black and white) to 68. they recover the original gradient completely. Though speaking truly, I'm not sure that this filter is designed to do precise maths, because the result of deltaE (CIE76) is calculated in linear gamma space, but blending happens in sRGB with gamma ~2.2. We might try to think about a bit more intuitive values for it, but then we will have to change the difference calculation algorithm itself. Could you specify what exactly was the usecase you tried to solve with the filter? Perhaps we could think about a better difference calculation algorithm then. -- You are receiving this mail because: You are watching all bug changes.
