Does anyone have a program they want to share that converts a raster
image to CCITT T4 (Group 3 facsimile) format?  Or even have the run
length code list in machine readable form?

I have the CCITT document.  The coding looks like some kind of
modified Huffman coding for black/white run lengths.  It shouldn't be
very hard to code, I just don't want to enter the 200 or so bit
patterns by hand.

Any help out there?
