JPEG != JPEG2000 Per the JPEG group JPEG2K is licensed, but the license is available free of charge. <http://en.wikipedia.org/wiki/JPEG_2000> <http://www.jpeg.org> in particular this page <http://tinyurl.com/ ypsh8e> which talks both about licensing and patent issues. Also this is an official statement by the JPEG on JPEG 2000 part 1 (the basic format): "Part 1 also includes guidelines and examples, a bibliography of technical references, and a list of companies from whom patent statements have been received by ISO. JPEG 2000 was developed with the intention that Part 1 could be implemented without the payment of licence fees or royalties, and a number of patent holders have waived their rights toward this end. However, the JPEG committee cannot make a formal guarantee, and it remains the responsibility of the implementer to ensure that no patents are infringed." Basically the techniques used may have patents. Bilski, however, really makes these sorts of patents iffy, at best. <http://tinyurl.com/6rygvc > -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
