I tried the current libtiff 4.0 beta, and found it lacks support for the extra tags defined for TIFF-FX files (RFC3949). I am wondering if that is simply because nobody did the work, or because it was intentionally left out. RFC3949 look a long time to be finalised, and there were patent wrangles between Xerox and Adobe for a while. It looks like that's all sorted out, though, and the IETF seems happy enough to have published RFC3949.

If there is nothing to block the addition of the relevant tags, I will cook up a patch to add support.


To the best of my knowledge there has never been TIFF-FX support in mainline libtiff. If you can provide a patch, and sample files via bugzilla there is a good chance of it making it in at some point.
