[GEM-dev] gem color bug

[marius schebella]

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.

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... (?)
