| 2007-12-19 | In mqc.h, changed MQC_NUMCTXS from 32 to 19 as JPEG 2000 only allows 19 ↵ | Francois-Olivier Devaux | |
| possible contexts | |||
| 2007-12-10 | First 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 ! | |||
| 2007-11-29 | Added index.h and index.c in VC6 projects; wrapped index.h in the C++ ↵ | Giuseppe Baruffa | |
| preprocessor; modified OPJViewer project and some files. | |||
| 2007-11-27 | Fixed the maximum number of resolutions a user can discard while decoding. | Francois-Olivier Devaux | |
| Added an error state in J2K_STATE (j2k.c) | |||
| 2007-11-27 | Created 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) | |||
| 2007-11-14 | Avoided ABI breakage | Francois-Olivier Devaux | |
| 2007-11-14 | Patch 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. | |||
| 2007-11-14 | Patch 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. | |||
| 2007-11-14 | Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now ↵ | Francois-Olivier Devaux | |
| just uses opj_realloc in j2k.c | |||
| 2007-11-13 | Patch 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. | |||
| 2007-11-08 | Patches from Callum Lewick: Fixed some spelling errors in dwt.c. | Francois-Olivier Devaux | |
| 2007-11-08 | In 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. | |||
| 2007-11-05 | Fixed a bug which prevented JPWL from working on multi-tiled images; added ↵ | Giuseppe Baruffa | |
| some more fields in the interface info structures (keep a list of markers, save start packet number for each tile) | |||
| 2007-10-23 | Improved success for the linux build; OPJViewer shows all the COM contents | Giuseppe Baruffa | |
| 2007-10-18 | Patch from Callum Lewick. Memset patch. See ChangeLog for more details. ↵ | Francois-Olivier Devaux | |
| Thanks Callum ! | |||
| 2007-10-18 | Changed the ROI parameter in the image_to_j2k codec to make it correspond to ↵ | Francois-Olivier Devaux | |
| the documentation (i.e. -ROI c=0,U=25) | |||
| 2007-10-12 | Changed the way the image structure is allocated when the decoding ↵ | Francois-Olivier Devaux | |
| 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 ! | |||
| 2007-10-10 | *Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff. | Francois-Olivier Devaux | |
| *convert.c: Changed some error comments for TIFF images | |||
| 2007-09-27 | Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was ↵ | Francois-Olivier Devaux | |
| problematic under x86_64. | |||
| 2007-09-25 | BUG: Fix previous patch from Callum Lerwick. I have no clue what ↵ | Mathieu Malaterre | |
| 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) | |||
| 2007-09-19 | Fixed issues with generation of SOP marker. | Parvatha Elangovan | |
| 2007-09-18 | Fixed issues with Reading and Writing TIF images in convert.c to avoid ↵ | Parvatha Elangovan | |
| segmentation fault. Fixed issues relating to using user specified rates for CINEMA option for multiple images. | |||
| 2007-09-17 | OpenJPEG library interface modified to retain compatibility with version ↵ | Francois-Olivier Devaux | |
| 1.2. Sorry if some of you already adapted their code to the previous interface, but we want to avoid a ABI break.... | |||
| 2007-09-17 | Fixed issues with cstr_info when codestream has components with different ↵ | Francois-Olivier Devaux | |
| number of resolutions. | |||
| 2007-09-12 | Patch from Callum Lerwick. Fixed the library linking so it links with the ↵ | Francois-Olivier Devaux | |
| soversion properly set. Fixes up the install targets so that it interacts properly with RPM. Install target for MJ2. Sets some necessary and useful CFLAGS if gcc is in use. | |||
| 2007-09-12 | Updated the MJ2 codec to be compatible with the recent changes in the ↵ | Francois-Olivier Devaux | |
| OpenJPEG library. | |||
| 2007-09-11 | JPWL encoding is finalized correctly into the JP2 file format; added an ↵ | Giuseppe Baruffa | |
| additional structure in opj_codestream_info, to keep a record of the written markers | |||
| 2007-09-07 | Adapted the JPWL and OPJViewer code to new interface; fixed a samll bug in ↵ | Giuseppe Baruffa | |
| JPWL which created large EPBs even when null protection was specified | |||
| 2007-09-07 | Indexes can now be generated when decoding J2K codestreams. | Francois-Olivier Devaux | |
| 2007-09-07 | ENH: Add cmake code to do testing if user has properly setup a testimages ↵ | Mathieu Malaterre | |
| directory | |||
| 2007-09-07 | ENH: Upon failure, properly return error code (!=0) | Mathieu Malaterre | |
| 2007-09-06 | ENH: Fix unitialized read in img_fol (we may need a smarter initialize than ↵ | Mathieu Malaterre | |
| memset) | |||
| 2007-09-06 | ENH: Add very simple tests (simply run command line with no option) | Mathieu Malaterre | |
| 2007-09-06 | One more field in the codestream_info struct for recording the number of ↵ | Giuseppe Baruffa | |
| packets per tile part; JPWL now distributes the EPBs in all the tile part headers | |||
| 2007-09-06 | ENH: Add CMake/doxygen output | Mathieu Malaterre | |
| 2007-09-06 | ENH: add Java j2kviewer but do not compile it using cmake since cmake has ↵ | Mathieu Malaterre | |
| too poor support for Java. Should create a custom command running ant instead. | |||
| 2007-09-06 | ENH: CMake: start compiling index_create. OpenJPEG.rc update copyright year | Mathieu Malaterre | |
| 2007-09-06 | ENH: CMake: output all executable/libs into one single directory | Mathieu Malaterre | |
| 2007-09-06 | ENH: update changelog | Mathieu Malaterre | |
| 2007-09-04 | Added some fields in the codestream_info structure: they are used to record ↵ | Giuseppe Baruffa | |
| the position of single tile parts. Changed also the write_index function in the codec, to reflect the presence of this new information. | |||
| 2007-09-03 | Added the knowledge of JPSEC SEC and INSEC markers (you have to compile the ↵ | Giuseppe Baruffa | |
| JPWL project). Management of these markers is limited to skipping them without crashing: no real security function at this stage. Deprecated USE_JPSEC and USE_JPWL will be removed next | |||
| 2007-08-31 | Fixed save capabilities in OPJViewer due to recent code upgrade | Giuseppe Baruffa | |
| 2007-08-30 | Added information regarding the end of packet position in the index | Francois-Olivier Devaux | |
| 2007-08-30 | Changed the OpenJPEG library interface to enable users to access information ↵ | Francois-Olivier Devaux | |
| regarding the codestream (also called index). | |||

| branchless code | |||
| 2007-08-21 | Consolidated some calls to mqc_setcurctx. Cleaned up t1_generate_luts to ↵ | Francois-Olivier Devaux | |
| output the proper types. | |||
| 2007-08-21 | Reworks of t1_updateflags to get rid of the shift operation. mqc_setcurctx ↵ | Francois-Olivier Devaux | |
| moved to the header to allow it to be inlined into the t1. | |||
