Subject [jira] [Commented] (SANSELAN-48) Sanselan cannot read CCITT compressed TIFF files
Date Sat, 09 Apr 2011 15:46:05 GMT


Damjan Jovanovic commented on SANSELAN-48:

The other thing we could consider is using the TIFF implementation from Apache XMLGraphics
Commons (
But I am personally hoping for one that's flexible enough to extract images directly out of
T.38 (fax over IP) packets, and that one can't (it needs to handle FILL among other things).
I've written a flexible but crude implementation to extract T.4 1D images, but (1) it needs
optimizing and cleaning up and (2) most fax machines now use T.4 2D or T.6 compression so
it's not very useful.

2 must be supported and types 3 and 4 are optional.
