Scanned pictures, removing huge black areas (win32)

Question

I have received a directory of scanned pages (png). Before printing them I would like to remove the huge black areas as they would waste tint. Is there a way to accomplish this using some batch processing tool?

I have heard that XnView might be able to do such thing.

Answer 1

I'm unfamiliar with XnView, but Gimp has a fairly robust batch processing capability
