IgorV noticed that alpha slider does not appear to work in bluebanana since ~april 2017 (?) I do not have specific files, I just tried to put jpeg wallpaper on track above video, add BB plugin to track with wallpaper.jpg, and colorpick some color there (so selectin will be visible) sadly moving alpha slider from 100 to 0 in BlueBanana does not have any effect on image in compositor? tried rgba-8, rgba-float, yuva8 (also plain x11 and opengl x11, with and w/o direct method). https://git.cinelerra-gg.org/git/?p=goodguy/history.git;a=history;f=cinelerr... I do not have pkg from that earlier era, but I'll try to compile sources on earlier system snapshot. Might take some time ...

In other emails, Igor Vladimirsky identified the commit after which the alpha slider is no longer functional: https://git.cinelerra-gg.org/git/?p=goodguy/history.git;a=commit;h=259e43548... If anyone can figure out where the problem lies, they are welcome. Perhaps in bluebanacolor.c, the line: float a = 1.f - *S*F; Which became: float a = *S*F; ?

I tried to reset this specific file back to git baseline (git checkout path/bluebananacolor.c ) and problem was still here ... So, I guess it was big if {} block in bluebananaengine.c (tried to put some printks there and code execution apparently hit this region of code)
What I know, "alpha" slider works with both "Filter Active" and "Mask Selection" checkboxes checked. The "Filter Active" checkbox enables the options: red, green, blue, hue, saturation, value, fade, *alpha*. If "Mask Selection" is not checked "alpha" will not work.

yeah, it seems that "end selection" also must be disabled for this to work ..... strange. Need to read documentation :)

Blue Banana is a complicated "work of art"! Since I have found a typo in the Manual in the Blue Banana plugin section, I will add Beghetto's summary of how alpha works as he stated below. Thanks too from me for the illustrative video. On Mon, Apr 1, 2024 at 3:59 AM Igor BEGHETTO via Cin < [email protected]> wrote:
