2008-08-22found a bug in tcd.c that was preventing to find the correct threshold in ↵Antonin Descampe
tcd_rateallocate.c for high-precision images. Applied a temporary patch but a better solution should be found.
2008-08-21fixed a bug in image_to_j2k.c that was preventing the 'r' option to work ↵Antonin Descampe
properly (everything was compressed lossless regardless of the specified rate).
2008-08-08Modified the way raw images with more that 8bpp are read and writtenFrancois-Olivier Devaux
2008-07-31Deleting v2 directory... Will be re-created as a branchAntonin Descampe
2008-07-09Added the default lossless parameter to opj_set_default_encoder_parameters ↵Parvatha Elangovan
in openjpeg.c
2008-07-04Initial commit of openjpeg version 2. Temprarily added as a separate ↵Antonin Descampe
directory in the trunk (will maybe be moved to a branch of version 1.3, this has to be investigated).
2008-06-12fixed a bug in dirent.h that prevented codec on Linux Alpha Systems to ↵Antonin Descampe
compile correctly. Thanks to RobinC.
2008-05-22fixed a bug in j2k.c (j2k_write_sod) that allowed to get negative rates, ↵Antonin Descampe
thanks zhong1985624 for pointing this.

2008-02-29Fixed openjpeg.c for proper initialization of codec context structures ↵Francois-Olivier Devaux
(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.
2008-02-28Removed the J2KViewer module, which has been replaced by OPJViewer and fixed ↵Francois-Olivier Devaux
the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius
2008-02-11Minor style modifications to comply with c99 compiler flag; removed ↵Giuseppe Baruffa
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
2008-02-05In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, ↵Parvatha Elangovan
corrected Rate modification in tcd_init_encode().
2008-01-31In opjviewer, unification of JPEG 2000 family handlers (*.jp2, *.mj2, *.j2k) ↵Giuseppe Baruffa
in a single file
2008-01-22In image.c, changed the opj_image_create0() memory allocation from malloc() ↵Francois-Olivier Devaux
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.

2007-12-10First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by ↵Francois-Olivier Devaux
Patrick Piscaglia of Telemis (www.telemis.com). Thank you Patrick for this new module !
2007-11-29Added index.h and index.c in VC6 projects; wrapped index.h in the C++ ↵Giuseppe Baruffa
preprocessor; modified OPJViewer project and some files.

Added an error state in J2K_STATE (j2k.c)
2007-11-27Created the file index.c in the codec directory. This file handles the ↵Francois-Olivier Devaux
creation of index files, at encoding and decoding. Fixed bugs during the creation of the index (PCRL progression order)
2007-11-14Avoided ABI breakageFrancois-Olivier Devaux
2007-11-14Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest ↵Francois-Olivier Devaux
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.
2007-11-14Patch by Callum Lerwick. This patch rearranges the largest memory ↵Francois-Olivier Devaux
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.
2007-11-14Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now ↵Francois-Olivier Devaux
just uses opj_realloc in j2k.c
2007-11-13Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which ↵Francois-Olivier Devaux
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.
2007-11-08BUG: Fix name of projectMathieu Malaterre
2007-11-08ENH: remove hardcoded value. It is a user-configurable option, which default ↵Mathieu Malaterre
