Jmage 0.7 was released as a compatibility release for Mac OSX, with some minor issues resolved that prevented it from running. Jmage 0.7 sheds the JAI-ImageIO dependency which was the last native tie it had into any OS. The distribution now ships with the "software only" version of JAI and should work on any Java platform on any OS. The result is a much leaner JMAGE distribution. Please note, support for .BMP and .TIF formats in JMAGE has been dropped since it relied on JAI-ImageIO which was platform dependant.
Software based support for these formats is possible in the future, however not currently on the road map. If you require either, the forums are a good place to post these requests.
