I'm interested in what the optimal method for compressing B/W fax images
(for agruments sake we'll allow both Fine and Standard resolution, but
this may not actually be the case -- comments?). I'm interested in pointers
to code that I can use or documents which would detail the method.
Also, what kind of compression ratio/effectivness/etc should I expect
from the methods you suggest? (On a single page image 1728x2200 [Fine] or
1728x1100 [Standard]).

Thanks,
	PG
