I would be interested in experiences people have had in scanning pages
of text or line drawings and reducing them.  Do people have any figures
for average sizes of the reduced bitmaps?

Tools like FAX use run-length encoding and some huffman to reduce their
bitmaps.  Are there any tools around that go significantly better.
(Other than OCR, of course.)

How small does a typical 8.5 by 11 page of stuff get when scanned at
300 by 300 and compressed?  I would guess 40K, but I would like to
find something that can take it down to 10K by being really smart about
what's being scanned.
