hi IOhannes, thanks for your answer. ok, I obviously tried two different things, one was to color my images, and the other one was to make parts transparent. I uploaded two new pics. http://www.parasitaere-kapazitaeten.net/Pd/Gem_bug I did not know that for coloring I do not need pix_alpha. sorry. so with pix_rgba and color I can color all white pixels. nice. otoh, the real bug seems to be in pix_alpha. it does not replace black pixels with alpha, but with blue... (?) marius.
I have tried today on MacPro MacOSX.4.10 with last Pd-extended and the bug is still there. When i want that black pixels on my video become transparent, they become blue. I also think that the bug seems to be in [pix_alpha], only on MacIntel, no problem on G4 !

hi, sorry for crossposting this on pd-list and gem-dev. there is a bug in the current cvs version of gem, that was already solved in summer, but now it seems back... I uploaded screenshots from the gem alpha color bug here: http://www.parasitaere-kapazitaeten.net/Pd/Gem_bug! what can I do to fix that? marius.
it seems to be a problem with blue and alpha being flipped. how does it look like when you put something behind the square (e.g. colorize the background with [color 1 1 1( to [gemwin])
what happens if you change the alpha value of the [colorRGB] object?
i don't have a macintel to test.
