My definition of "reasonable licensing" for a standard interchange format would be "free to anyone, forever, with minimal effort". I did a brief googleing of "jbig patent", and the best reference on jbig2 I found was: http://www.jpeg.org/jbig/faq.phtml?action=show_answer&question_id=q3f042a7298c94 Apparently there are only two known patentholders relevant to jbig2, IBM and Mitsubishi, both of which are offering free licensing. I will be testing this, but if anyone has more reliable info, I'm curious. So, it would seem that free JBIG2 implementations, and JBIG2 in TIFF, should be feasible. -- Glenn Widener SwiftView, Inc.
