Hmm, I don't know anything about OpenApoc, so I'll have to look it up. The size of the source image and output images can be increased without much trouble, but I'm not so sure it will look good. I'll try it. There is also the minor problem of the speed of the program. For larger images, it will slow down even more than it already is. But I think I can still optimize it.

I haven't really made it robust, as I was just using it for myself and knew what to do. If you have a bug report, I guess you can post it here?
I don't have it in a versioning system, but maybe I'll convince myself to put it there one of these days.

I've tried coming up with something for units, but it's complicated. They end up looking like gingerbread aliens. So I'm not so sure it would be useful. The input would basically have to be images from all sides and even so, it probably won't come out looking all that great.
But maybe it can still work as a fast prototyping tool? Just the basic rotations, maybe some cutting up. I haven't tried making any units myself, so the process is unknown to me. If there really is a demand for that I can try to make it.
