Giuseppe Baruffa 95d760a173 Fixed a bug which prevented JPWL from working on multi-tiled images; added some more fields in the interface info structures (keep a list of markers, save start packet number for each tile) 2007-11-05 13:05:07 +00:00

Francois-Olivier Devaux 1f11a4fe90 Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard. This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
Warning: The output image size is now reduced when discarding resolutions !
