Hi Robert, ... Pipelined (non-preemptive) requests can be issued on a single channel by including the "wait=yes" request field. I believe this all works ...
Hi, I'm developing a Jpeg 2000 viewer. I found that Kakadu is more faster for decompressing than Jasper. At ur convinience i request you to tell me if i port...
