Thanks a lot for your help. For various reasons I couldn't implement it exactly like you suggested, what I did do in the end was something like this:
toSave = [[UIImage alloc] initWithCGImage:
CGBitmapContextCreateImage(_myContext);];
Later I save it to the album.
This works but for two problems, which you might be able to help me with:
1. The images are saved "mirrored" on the horizontal axis. It's pretty weird, like 'v' would become '^'.
2. The thumbnails in the photoalbum are solid black, no matter what I draw.
Any suggestions?
