Hi all,
i'm trying to use jitter as interface for a perceptual experiment on color. I want to modify an image, substituting a color in the area of transparency. For this i use PNG images. I know how to isolate the panes of a matrix but i don't know ho to put them back together.

i join my patch

Don't have time to look at the patch right now, but did you look at jitter tutorial 5 and 6? That should put you on the right track.
