I have software that does this off line. You have to fill the region with
black using a paint program. Then use resedit to create a file
containing all of the picts. Then this program creates regn resources for
all of the filled areas in the picts.
I didn't write it, so I don't know precisely how it works, but if you are
interested, email me at rees+@pitt.edu and I'll send you a stuffed
binhexed archive.
