Hello Martin,

thanks for the advice. I tried it but the effect is not exactly what I need: The sources are black/white tiffs. Because of the nature of blending one picture into another, both pictures black & white parts look kinda bad :(

Someone told me that with the LeadTools (funny name <_<) it would be possible to do some kind of mathematic: you (apparently) can tell the tools: take both pictures, and if a pixel is black in one of the pictures, make the target pixel in the output file black too. That's similiar to blending but it should save the black/white parts of the tiff.

Is something like that possible with Perl::Magick? I tried the XOR functions, the different combining functions etc but still I'm not able do to that.

Perhaps it's not possible to do what I would need but if there is a chance please tell me. And even if I fail I learned something about manipulating images with perl so it wasn't for nothing :D

Thanks for your help in advance,
Shinama
