The reason you did not Fri, 20 Nov 2009 02:05:45 GMT dieter_vh23 http://tech.groups.yahoo.com/group/kakadu_jpeg2000/message/5978 http://tech.groups.yahoo.com/group/kakadu_jpeg2000/message/5978 Dear all, we are running some tests to use JPEG2000 as the master format to store the scans of our archives.

Basically, the file format consists of a Mon, 16 Nov 2009 03:29:52 GMT kasana_s http://tech.groups.yahoo.com/group/kakadu_jpeg2000/message/5975 http://tech.groups.yahoo.com/group/kakadu_jpeg2000/message/5975 Hi I have a doubt about the header bytes used by Kakadu. Suppose I have an image of 128x128 and I want to compress it at the rate of 1 bit per pixel.
