From this forum thread:
https://www.cinelerra-gg.org/forum/help-video/problem-with-colour3way/ After the patch to make Color3way work in float, even with values above the range (0 - 1.0f), this problem occurs: "If I move the Shadows Value slider to the left, by the time it reaches 0.006 the image is almost totally black, which makes it totally useless." and: "I confirm the problem. The color wheel also behaves the same way, while the saturation slider works normally. Midtone and Highlight work normally." The applicated HDR patches can be seen here: https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=commitdiff;h=3cd... I've tried a few builds/tests. The patches for Overlays and for Histogram plugin seem to work normally. Only the patch for Color3way causes a problem. This problem occurs only for shadows, which is strange because the patch only alters the white boundary and leaves the black boundary unchanged. I tried to read the plugin code but I am not able to understand the problem. Does anyone understand anything about it? For now you could exclude the Color3way patch but put the other two back in. PS: Using the overlays in the patchbay seems to me that the PorterDuff do not work. This does not depend on the patch because I have the same behavior even with the old appimages without the patch...

I was wondering about Histogram and Overlayframe and was just being overly cautious by backing them out. So unless someone mentions a problem with them before Feb. 29, I will add those 2 back in. Meanwhile, I will at least see if I can reproduce the color3way issue and look at the code, but do not expect I can solve it.

In about October of 2022, I spent a lot of time looking at all of these to
assure myself that they were working as documented and comparing them to output from Gimp and SVG. This was because IgorV made a note in his blog that at least one of them was all wrong -- it was not, and that was because of history and design differences. I found the following necessary as a reminder of how to get the expected results with PorterDuff. https://cinelerra-gg.org/download/CinelerraGG_Manual/Description.html <https://cinelerra-gg.org/download/CinelerraGG_Manual/Description.html> Just now, in comparing the results with the alternative views in the manual, the PorterDuff matches what I see. I will send Andrea the png file I used as the base to be used with any other landscape png on the second track - both of which better illustrate the results when offset as shown in the manual.
