The TIFF format was invented originally for the DEST line of scanners. My
documents say "March 7, 1988, Bear River Associates, Inc., Berkeley,
CA" There is a review article on the subject in a Dr. Dobbs somewhat
less than one year ago.  The spec itself is about 30 pages long and
includes Lempel-Zivv compression as a utility procedure to optionally
compress picture data.  It also includes a portion of the FAX standard as
an optional method of storing picture data.

I only have source for C procedures for version 4 of the spec.  (Bear
River gave them away, for plublicity and to clear space on their
shelves for version 5.)

It is a decent machine-independent standard for scanned, and especially
gray scale or color scanned images.

If you actually use the compression features, you shrink your images to
1/3 or smaller of their original size.  But, the extra cpu time can be
painful.

Conclusion:
If you find ordering nformation for the current standard, please let me
know. I'd like to update my version 4 stuff.
