Is there any specification on JBIG encoding for TIFF?

I didn't double-check, but at some point I seem to have added to the Compression tag page:

<quote from http://www.awaresystems.be/imaging/tiff/tifftags/compression.html>

The TIFF-F specification (RFC 2301) defines:

9 = Defined by TIFF-F and TIFF-FX standard (RFC 2301) as ITU-T Rec. T.82 coding, using ITU-T Rec. T.85 (which boils down to JBIG on black and white). 10 = Defined by TIFF-F and TIFF-FX standard (RFC 2301) as ITU-T Rec. T.82 coding, using ITU-T Rec. T.43 (which boils down to JBIG on color).

</quote>

So presumably that means this RFC 2301 http://www.ietf.org/rfc/rfc2301.txt had some specification of JBIG in TIFF.

Amongst the LibTiff values enumerated on that page is COMPRESSION_JBIG = 34661, though, so presumable there's some other competing specification as well, but I haven't got a clue where to start looking for it.

Please let us know if you find anything more defenite.
