Francois-Olivier Devaux 010ae27471 Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further. 2007-11-14 10:52:02 +00:00
Francois-Olivier Devaux 24e189e4d8 Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images. 2007-11-14 08:45:00 +00:00
Francois-Olivier Devaux 61a15672bb Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c 2007-11-14 08:29:12 +00:00
Francois-Olivier Devaux dbeebe72b9 Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy. 2007-11-13 17:35:12 +00:00

Giuseppe Baruffa b93c12564d Restoring wrap_j2k_in_mj2.c, which I did not want to commit at all in rev469 2007-11-05 13:14:51 +00:00
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
Giuseppe Baruffa 123a680669 Improved success for the linux build; OPJViewer shows all the COM contents 2007-10-23 14:33:40 +00:00
Francois-Olivier Devaux 9e114bcaa4 Patch from Callum Lewick. Memset patch. See ChangeLog for more details. Thanks Callum ! 2007-10-18 12:26:11 +00:00
Francois-Olivier Devaux 5fdc05d18d Changed the ROI parameter in the image_to_j2k codec to make it correspond to the documentation (i.e. -ROI c=0,U=25) 2007-10-18 08:14:43 +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 !

Mathieu Malaterre 6265dcfb11 BUG: Fix previous patch from Callum Lerwick. I have no clue what CMAKE_INSTALL_LIBDIR refers too.
