Those green areas in Enhancer

[greybeard]

Hi AKVIS,

I thought that you meant the defect in the picture "Enhancer green 96K.JPG".

The black (very dark) areas show up in Enhancer's preview as bright green and then show up dark in the processed image. So the bug under discussion has two aspects: a Preview bug and a processing bug. A bright green area in the Preview serves (perhaps unintentionally) as a warning that an erroneously dark area is going to show up in the processed image.

If it develops that the foibles of integer arithmetic are behind this problem, you might want to consider going to floating point arithmetic for your image processing and then convert the results to integer RGB for the output file. Other leading graphics programs have finally adopted this approach. If you haven't already done that, circumstances may eventually make that conversion attractive for you.

But we can't reproduce your bright green color.
We would not believe in this if it were not your screenshot.

You are right about the dark zone (it's dark) but it must work in such way with our algorithm.
As for bright green - we do not see this.
