2006.05.31 16:56 "OT: jbig2 patent licensing", by Alberto Accomazzi
Forgive the slightly offtopic question, but I know that many people on the list are involved in compression and I need some help. As you may know, there is now a JBIG2 open source encoder available (for arithmetic encoding) which looks promising: http://www.imperialviolet.org/jbig2.html I would like to use the software to create and distribute jbig2 compressed data in PDF files for the non-profit project I work on. Am I correct in saying that even as a user I need to worry about obtaining the proper licenses from IBM and Mitsubishi just so I can use the encoder? The only info on JBIG2 patents I found is here: http://www.jpeg.org/jbig/faq.phtml?action=show_answer&question_id=q3f042a7298c94 And what exactly are the patents in question?
