Does anybody know which programming library I should use to throw a transparent PNG on top of a JPG and export a layered file for photoshop ? like a TIF or PSD or anything that can be loaded in photoshop.
I know the GD library can be used to output to screen or a non-layered file, but I'm wondering is there any format I can output to with proper intact layers...
Preferably something clientside with JS but I can do PHP serverside if that's my only option. I've done a bit of googling on the subject, hard to format the search really.
Any ideas would be really appreciated. Thanks !
