2010-11-25Fix leak in jp2_read_header_procedure() (from even.rouault, see issue 29 on ↵Antonin Descampe
googlecode)
2010-10-07The original v1.3 branch had:Mathieu Malaterre
((int*)tiledp)[(j * tile_w) + i] = tmp / 2; while v2 had: ((OPJ_INT32*)tiledp)[(j * tile_w) + i] = tmp >> 1; Divide by two and a right shift operation are only equivalent when the data is unsigned. In this case the data is signed, so the right shift operation is incorrectly clearing the sign bit. Patch from: Sheet Spotter

2010-08-22The lrintf function should use "long" instead of "int"Luis Ibanez
for the type of its internal variable.
2010-08-22BUG: The _asm directive is not available in Visual Studio 9, 64bits.Luis Ibanez
An alternative vainilla implementation has been added here, based on code from VXL, vnl_math.h.

2010-08-20BUG: Fixing case in which the pointer the data buffers doesn'tLuis Ibanez
get positioned at the beginning of the buffer after a new buffer load. This case only happens when the pointer happens to be at the end of the buffer when the request for the new block arrives. Fix contributed by Bill Hoffman.

Winfried for this patch.
2010-01-20[FOD] Created a new constant in openjpeg.h to differentiate the case when ↵Francois-Olivier Devaux
the colorspace is not supported by the library and when it is not specified in the codestream. Suggested by Matteo Italia.
2009-09-10V2 branch : Antonin Descampe
- found a bug in tcd.c that was preventing to find the correct threshold in tcd_rateallocate.c for high-precision images. Applied a temporary patch but a better solution should be found. - Modified the way raw images with more that 8bpp are read and written
2008-08-02ENH: remove INLINE from forward decl. Fix CMakeLists.txt for UNIX platformsMathieu Malaterre

(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2008-02-28Removed the J2KViewer module, which has been replaced by OPJViewer and fixed ↵Francois-Olivier Devaux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
2008-02-05In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, ↵Parvatha Elangovan
corrected Rate modification in tcd_init_encode().
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.

Patrick Piscaglia of Telemis (www.telemis.com). Thank you Patrick for this new module !
2007-11-27Fixed the maximum number of resolutions a user can discard while decoding.Francois-Olivier Devaux
Added an error state in J2K_STATE (j2k.c)
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.
2007-11-08Patches from Callum Lewick: Fixed some spelling errors in dwt.c.Francois-Olivier Devaux
2007-11-08In t1.c, small change to avoid calling twice t1_getwmsedec()Francois-Olivier Devaux
Patch from Callum Lewick. Basic gcc optimization flags in cmake and makefile match.
