I think I may have found (kinda) what I was looking for, I found the function pixel_to_bmap() in AUM 40, but it seems to be a a6 function, which is lame because I don't see how it could do anything remotely complex, anyway, can anyone tell me if pixel_to_bmap() or something similar is in the A5 version, or will I have to wait until I get the nerve (and money) to upgrade to a respectable A6 version?
