I replied to Paul with info about TTN2 and the great description of writing JPEG-in-TIFF contained therein.
Why is TTN2 not on the www.libtiff.org web page?
I found it at ftp://ftp.sgi.com/graphics/tiff/TTN2.draft.txt
A good question with no good answer. It's been added now -- http://www.libtiff.org/document.html
