Francois-Olivier Devaux 6d1f3ecc9f Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress() and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev
Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(), as apparently memalign() is what is working better for everyone. Patch by Callum.

Francois-Olivier Devaux 396cb1e102 Removed the J2KViewer module, which has been replaced by OPJViewer and fixed the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius 2008-02-28 11:26:04 +00:00
Giuseppe Baruffa ac0cc6df62 Minor style modifications to comply with c99 compiler flag; removed Microsoft-specific "union-in-struct" syntax; Re-enabled cstr_info struct creation when -W switch is specified. Changed a number of things in opjviewer (e.g., decoding thread does not execute GUI calls anymore), to have it running under linux --> it is better than before, but still crashes 2008-02-11 14:43:11 +00:00
Parvatha Elangovan 29ea3dde47 In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, corrected Rate modification in tcd_init_encode(). 2008-02-05 15:15:38 +00:00

Francois-Olivier Devaux 04966097fc In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order to avoid segfaults when freeing the memory allocated for the coding of bad images. Thanks to Christopher Layne for this improvement. 2008-01-22 10:35:26 +00:00

Francois-Olivier Devaux c458af9cd6 Avoided ABI breakage 2007-11-14 11:34:48 +00:00
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
Francois-Olivier Devaux 4bb067642f Patches from Callum Lewick: Fixed some spelling errors in dwt.c. 2007-11-08 14:29:39 +00:00
Francois-Olivier Devaux c38de0728d In t1.c, small change to avoid calling twice t1_getwmsedec()
Patch from Callum Lewick. Basic gcc optimization flags in cmake and makefile match.
2007-11-08 14:26:03 +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 !
2007-10-12 15:04:34 +00:00
Francois-Olivier Devaux ab0473aa42 *Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff.

Mathieu Malaterre 6265dcfb11 BUG: Fix previous patch from Callum Lerwick. I have no clue what CMAKE_INSTALL_LIBDIR refers too. Bump up cmake 2.2 restriction to cmake 2.4 because of previous patch not backward compatible. Properly set the SOVERSION in a cross plateform way (yes WIN32 is a plateform) 2007-09-25 14:54:49 +00:00
Parvatha Elangovan 7e40a9475a Fixed issues with generation of SOP marker. 2007-09-19 14:56:19 +00:00
