How to decompose sprite sheet
I'm doing a port of an existing game and the designer no longer has all of the original art; he only has the resulting texture atlases he used when developing for iPad. The tool I'm using won't support these files so I need to break them back out into separate PNG files.
I'm hoping someone knows of a software tool that does this. PC software would be preferred in this case, but Mac would suffice.
To add some clarification; these texture atlases are in a simple gridded layout with even distribution and not packed. No need to tie back to descriptor files; I just need a simple animation splitter type of tool where I can tell it the size of a frame, point it to the image and from that get a set of separate images.
