Essentially, overlay all the pixels that are not black.
Is there a library or set of functions somewhere that makes this easy? I remember a while back thinking I would have to write my own overlay/masking utilities to get this behavior, but I hope that's not true.
It should be fairly straightforward, if I understand correctly: mask = (img2 != 0) img1[mask] = img2[mask] Regards Stéfan
