 11November 5, 2009
 12* [antonin] fixed "tiffio" header inclusion to use user version on Win32 system only (otherwise assume its existence in system headers).
 14September 10, 2009
 15* [antonin] fixed minor bugs which were triggering warnings at compilation (different signedness, wrong pointer type, etc)
 17September 8, 2009
 18* [antonin] openjpeg.c : fixed initialization of parameters->cp_disto_alloc/fixed_quality/fixed_alloc/tcp_numlayers because they were preventing to use the -q and -f options.
 20August 31, 2009
 21* [antonin] JavaOpenJpegDecoder.c : fixed a signed/unsigned behaviour when returning form C to JAVA
 23August 21, 2008
 24* [antonin] 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.
 26August 21, 2008
 27* [antonin] fixed a bug in image_to_j2k.c that was preventing the 'r' option to work properly (everything was compressed lossless regardless of the specified rate).
 29August 8, 2008
 30! [FOD] Modified the way raw images with more that 8bpp are read and written
 32July 9, 2008
 33+ [Parvatha] Added the default lossless parameter to opj_set_default_encoder_parameters in openjpeg.c.
 35June 12, 2008

 51! [FOD] Changed Java files copyright in JavaOpenJPEG module
 53February 28, 2008
 54* [FOD] Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress() 
 55		and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev
 56* [FOD] Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(), 
 57		as apparently memalign() is what is working better for everyone. Patch by Callum.
 59February 28, 2008
 60- [FOD] Removed the J2KViewer module, which has been replaced by OPJViewer
 61* [FOD] Fixed the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius

 64* [GB] 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
 65! [GB] 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
 67February 5, 2008
 68! [Parvatha] In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, corrected Rate modification in
 69  tcd_init_encode(). Thanks to Jeremy Furtek and Jérôme Fimes.
 71January 31, 2008
 72! [GB] In opjviewer, unification of JPEG 2000 family handlers (*.jp2, *.mj2, *.j2k) in a single file
 74January 22, 2008
 75! [FOD] In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order
 76		to avoid segfaults when freeing the memory allocated for the coding of bad images.
 77		Thanks to Christopher Layne for this improvement. 
 79January 17, 2008
 80+ [antonin] Initial commit of Xcode project directory (XCode 2.5 for macosx)
 81			available targets : libopenjpeg (stat and dyn), image_to_j2k, j2k_to_image
 83January 16, 2008
 84* [antonin] fixed opj_malloc.h for macosx (bugfix provided by janpeder, thanks)
 86January 11, 2008
 87+ [FOD] Added missing files to JavaOpenJPEG project (files from Patrick Piscaglia)
 89January 4, 2008
 90* [Parvatha] Patch by Callum Lerwick. Fixed bug during encoding using tile option in tcd.c
 93December 21, 2007
 97December 21, 2007
 98* [FOD] Bug fixed by David Bruken. Fixed memory allocation issue in opj_malloc.h
 99! [FOD] Possible errors in pi_create_encode handled
101December 19, 2007
102* [Antonin] changed variables names alpha, beta, gamma, delta in dwt.c to avoid re-declarations on Macosx
103! [Parvatha] In pi.c, removed the Recursive function pi_check_next_level() and modified the code.
104* [FOD] Fixed allocation problem in pi.c
106December 19, 2007
107+ [FOD] In mqc.h, changed MQC_NUMCTXS from 32 to 19 as there are only 19 possible contexts
109December 10, 2007
110+ [FOD] First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis ( 
111		Thank you Patrick for this new module !
113November 29, 2007
114! [GB] Added index.h and index.c in VC6 projects; wrapped index.h in the C++ preprocessor; modified OPJViewer project and some files.
116November 14, 2007
117+ [FOD] Created the file index.c in the codec directory. This file handles the creation of index files, 
118		at encoding and decoding. 
119* [FOD] Fixed bugs during the creation of the index (PCRL progression order)
120* [FOD] Fixed the maximum number of resolutions a user can discard while decoding.
121		Added an error state in J2K_STATE (j2k.c)
123November 14, 2007
124! [FOD] - First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
125		- Second Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as 
126		late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.
127		- Third Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it
128		contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates 
129		the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size 
130		them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate 
131		encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.
133* [FOD] Avoided ABI breakage
135November 13, 2007
136! [FOD] Patch by Dzonatas and Callum Lerwick.
137        Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point,
138        eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement,
139	and an increase in accuracy.
141November 8, 2007
142! [FOD] In t1.c, small change to avoid calling twice t1_getwmsedec()
143        Patches from Callum Lewick:
144		- Basic gcc optimization flags in cmake and makefile match.
145		- Fixed some spelling errors in dwt.c.
147November 5, 2007
148*+ [GB] Fixed a bug which prevented JPWL from working on multi-tiled images; added some more fields in the interface info structures 
149(keep a list of markers, save start packet number for each tile)
151October 23, 2007
152* [GB] Improved success for the linux build; OPJViewer shows all the COM contents
154October 18, 2007
155* [FOD] Changed the ROI parameter in the image_to_j2k codec to make it correspond to the documentation (i.e. -ROI c=0,U=25)
156* [FOD] Patch from Callum Lewick. Memset patch. 
157		The main idea of the patch is that currently opj_malloc clears all allocations, which unnecessarily
158		dirties up the cache and eats bandwidth. This patch makes it no longer do so, and I've painstakingly determined which allocations actually need
159		to be cleared and changed them to use opj_calloc() instead. I previously tried to just get rid of the opj_*alloc wrappers but that
160		idea was nixed, so this time I'm trying it with macros. I also put in a gcc pragma that helps enforce their use. Which got messy.  :)  It caught a
161		few places they weren't used but it also revealed that the mj2 tools are not very cleanly separated from the library. It includes all the
162		internal headers, but it wasn't using the malloc wrappers. I figured the binaries should be "external" and have minimal knowledge of the
163		internals of the library. I patched them to not include opj_includes.h, and include only the internal headers they actually need. However,
164		they're using the opj_clock() function, which is in with the malloc wrappers. So I decided to move the malloc wrappers to their own header. 
165		But mj2.c seems to want to be "internal", so I patched it to use the wrappers. Note that this patch changes the semantics of opj_malloc, it no longer
166		clears the memory it allocates. If you need it to be cleared, you must use opj_calloc instead, or memset it yourself. It is also somewhat
167		invasive, please test it extensively. I've been pounding on it all summer with my test suite, Second Life, and valgrind, and it checks out clean.
169October 12, 2007
170* [FOD] Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard. 
171        This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
172        Warning: The output image size is now reduced when discarding resolutions !
174October 10, 2007
175* [FOD] Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff. 
176        It makes it work right with mingw, as _mm_malloc() isn't a macro, attempts to pave the way to using cmake 
177        to check for this stuff and combines a patch from Dana Fagerstrom at Sun that makes it use memalign() on Solaris
178        convert.c: Changed some error comments for TIFF images
180September 27, 2007
181* [FOD] Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64.
183September 25, 2007
184* [Mathieu Malaterre] BUG: Fix previous patch from Callum Lerwick. I have no
185    clue what CMAKE_INSTALL_LIBDIR refers too. Bump up cmake 2.2 restriction to
186    cmake 2.4 because of previous patch (not backward compatible). Properly set the SOVERSION in a cross plateform way (yes WIN32 is a platform)
188September 19, 2007
189* [Parvatha] Fixed issues with generation of SOP marker. 
191September 18, 2007
192* [Parvatha] Fixed issues with Reading and Writing TIF images in convert.c to avoid segmentation fault. 
193* [Parvatha] Fixed issues relating to using user specified rates for CINEMA option for multiple images.
195September 17, 2007
196* [FOD] Fixed issues with cstr_info when codestream has components with different number of resolutions. 
197! [FOD] OpenJPEG library interface modified to retain compatibility with version 1.2 
199September 12, 2007
200* [FOD] Patch from Callum Lerwick.
201		Fixed the library linking so it links with the soversion properly set. 
202		Fixes up the install targets so that it interacts properly with RPM. 
203		Install target for MJ2. Sets some necessary and useful CFLAGS if gcc is in use.		
204* [FOD] Updated the MJ2 codec to be compatible with the recent changes in the OpenJPEG library
206September 11, 2007
207* [GB] JPWL encoding is finalized correctly into the JP2 file format; added an additional structure in opj_codestream_info, to keep a record of the written markers
209September 8, 2007
210* [GB] Adapted the JPWL and OPJViewer code to new interface; fixed a samll bug in JPWL which created large EPBs even when null protection was specified
212September 7, 2007
213+ [FOD] Indexes can now be generated when decoding J2K codestreams.
214* [Mathieu Malaterre] Upon failure, properly return error code (!=0).
215* [Mathieu Malaterre] CMake: Add cmake code to do testing if user has properly setup a testimages directory
217September 6, 2007
218+ [Mathieu Malaterre] CMake: start compiling mj2, jpwl and jp3d
219+ [Mathieu Malaterre] CMake: output all executable/libs into one single directory
220+ [Mathieu Malaterre] CMake: start compiling index_create
221+ [Mathieu Malaterre] OpenJPEG.rc update copyright year
222+ [Mathieu Malaterre] CMake: add Java j2kviewer but do not compile it using cmake since cmake has too poor support for Java. Should create a custom command running ant instead.
223+ [Mathieu Malaterre] CMake: Add doxygen output
224+ [GB] One more field in the codestream_info struct for recording the number of packets per tile part; JPWL now distributes the EPBs in all the tile part headers
225+ [Mathieu Malaterre] CMake: Add very simple tests (simply run command line with no option)
226* [Mathieu Malaterre] Fix unitialized read in img_fol (we may need a smarter initialize than memset)
228September 4, 2007
229+ [GB] Added some fields in the codestream_info structure: they are used to record the position of single tile parts. 
230		Changed also the write_index function in the codec, to reflect the presence of this new information.
232September 3, 2007
233+ [GB] Added the knowledge of JPSEC SEC and INSEC markers (you have to compile the JPWL project). Management of these markers is limited to skipping them without crashing: 
234		no real security function at this stage. Deprecated USE_JPSEC will be removed next
236August 31, 2007
237* [GB] Fixed save capabilities in OPJViewer due to recent code upgrade
239August 30, 2007
240* [FOD] Changed the OpenJPEG library interface to enable users to access information regarding the codestream (also called codestream index).
241		This index is usefull for all applications requiring to have a scalable acces to the codestream (like JPIP applications, ...)
242        Currently, this information is only available when encoding an image.       
243+ [FOD] Added the information regarding the end of packet position in the index        
245August 28, 2007
246* [FOD] Fixed wrong destructors called in openjpeg.c
247* [FOD] Fixed bug in j2k_decode_jpt_stream
249August 24, 2007
250* [Parvatha] The end of main header is calculated after TLM and POC marker for Dcinema.
252August 21, 2007
253+ [FOD] Added support for Visual Studio 2005
254* [FOD] Robustified MJ2 codecs
255* [Parvatha] Solved problems with codec reading from image file directory when filename had more than one "." in name
256* [Callum Lerwick] Minor cleanup patch, that gets rid of a bunch of "old style declaration" warnings from Intel's compiler
257* [Callum Lerwick] Aligned malloc using Intel's _mm_malloc(). Cleanup on the t1 memory allocation, getting rid of some leftover debug code
258* [Callum Lerwick] Memory leaks fixed
259* [Callum Lerwick] Reworks of t1_updateflags to get rid of the shift operation
260* [Callum Lerwick] mqc_setcurctx moved to the header to allow it to be inlined into the t1.
261* [Callum Lerwick] Consolidated some calls to mqc_setcurctx.
262* [Callum Lerwick] Cleaned up t1_generate_luts to output the proper types.
263* [Callum Lerwick] Replaced the large ctxno_mag lookup table with a small bit of inline-able branchless code
264* [Callum Lerwick] Moved the orient flipping into the ctxno_zc table.
266August 20, 2007
267+ [FOD] Added support for the TGA file format in the codec
269August 08, 2007
270* [Parvatha] Fixed the DCinema filesize allocation. It now includes the SOT marker size
272August 02, 2007
273+ [GB] Added a basic saving capability to OPJViewer
275July 18, 2007
276! [FOD] Updated libtiff library version to 3.8.2 (for WIN32)
277* [FOD] Updated BMP and PxM truncation when decoding J2K files with more than 8 bits
279July 17, 2007
280* [FOD] Fixed raw option for images with more than three components
282July 17, 2007
283+ [FOD] Added support for RAW images. This module has been developped by the University of Perugia team. Thanks to them ! [image_to_j2k.c j2k_to_image.c convert.c convert.h]
285July 13, 2007
286! [FOD] Modified the memory allocation for codestreams containing multiple tiles. The memory is now allocated for each tile indenpendently, 
287		leading to an important decrease of the virtual memory needed. [j2k.c tcd.h tcd.c]
288! [FOD] Modified old comments about the ability to decode mega-images and comments about the disk size necessary to do this. [image_to_j2k.c and frames_to_mj2.c]
289* [FOD] Added 2000 bytes for the memory allocation in cio.c for the minimum size of headers (useful in case of very small images) [cio.c]
291July 12, 2007
292* [GB] fixed a bug in JPWL module, which prevented to exploit the full error correction capability of RS codes (e.g. it gave up at 5 errors, 
293		even if 6 were correctable); defined a JPWL_MAXIMUM_EPB_ROOM for better customization of the maximum dimension of EPBs (the dimension 
294		is pre-calculated on an hypothesis, if it goes beyond 65535 there will be problems, thus we give a little less than the max, let's say 65450)
296July 8, 2007
297* [ANTONIN] fixed the size of the memory allocation in cio.c (confusion between bits and bytes)
299June 21, 2007
300* [FOD] Output image color space set when decoding a JP2 file in jp2.c
301+ [GB] Previous, home, and next frame buttons for exploring MJ2 files in OPJViewer
303June 18, 2007
304* [GB] Reload image doesn't crash in OPJViewer; more settings saved to registry
306June 16, 2007
307+ [GB] Possibility to disable parsing in OPJViewer; also, saves common settings to the registry
309June 15, 2007
310* [FOD] Fixed the generation of index files 
314MAY 4, 2007
318May 4, 2007
319* [FOD] Bugs corrected in decoding of command line (getopt.c), in the handling of 16 bit files (t1.c and tcd.c) and the calculation of elapsed time for multiple tiles parts (tcd.c and tdc.h).
321June 2, 2007
322+ [GB] OPJViewer opens now BMP, PNG, GIF, PNM, TIFF (with wxWidgets internals); added an encoder settings tab, for future integration with "save file as..." in JPEG 2000 format
324May 31, 2007
325* [FOD] Fixed the handling of 16bit TIFF files for cinema compression. Modified "convert.c"
326* [FOD] Fixed the parameters used for cinema compression (9-7 transform used instead of 5-3). Modified "image_to_j2k.c"
328May 24, 2007
329* [FOD] Bug fixed by Sylvain Munaut. Change in the reading of the POC marker. Since COD/COC can be anywhere in the header, the decoder cannot always know while decoding the POC marker 
330		the value of numlayers and numresolution.
332May 23, 2007
333! [FOD] Patch suggested by Callum Lerwick <>: "This makes the t1 data arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts"
335May 22, 2007
336! [FOD] Patch suggested by Callum Lerwick <>: "Some formatting cleanups, 
337		so that the long function definitions and calls fit on screen. Use of prefix increment which is theoretically faster, in practice any sane compiler can optimize a postfix 
338		increment but its best not to count on such things. Consolidation of some redundant calculations in the inner loops, which becomes very useful in the future autovectorize patch."
339! [FOD] Patch suggested by Callum Lerwick <>: "This changes the flag code in t1 to use a flag_t type, which can then be changed to reduce RAM usage. It is now typedef to a short."
340! [FOD] Patch suggested by Callum Lerwick <>: "This patch makes the t1 LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely."
342May 11, 2007
343- [FOD]	JP3D library Binaries removed from SVN.
344! [FOD] MJ2 codec updated from LibOpenJPEG version 0.97 to LibOpenJPEG version 1. Hence, the MJ2 codec will now take advantage of all the improvements and optimizations done on the LibOpenJPEG library.
345! [FOD] Possibility to choose to apply MCT (multiple component transform) enabled, and new decoding_limit: DECODE_ALL_BUT_PACKETS (openjpeg.h)
347April 26, 2007
348+ [gdcm] Add basic steps on how to use CMake for building examples (README.cmake)
350April 25, 2007
351+ [FOD] Modification of the openjpeg.h file to avoid and ABI break with v1.1, removed the dangerous #IFDEF JPWL and added tcp_mct in cparameters.
353April 23, 2007
354+ [GB] Enable/disable image decoding in OPJViewer
356April 12,2007
357* [Parvatha] Fixed Error in tiftoimage(). Modification in convert.c.

360+ [Parvatha] Accepting "j2c"  as format for Encoding and Decoding. Modification in image_to_j2k.c.
361* [Parvatha] Modified imagetotif() to read images with signed data. Modification in convert.c.
363April 5, 2007
364! [FOD] fix.h optimized. Thanks a lot to Dzonatas <dzonatas at> !
365! [FOD] dwt.c optimized. Thanks a lot to Dzonatas <dzonatas at> !
366! [FOD] t1.c optimized. Thanks a lot to Callum Lerwick <seg at>  !
368April 4,2007
369+ [Parvatha] Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification in image_to_j2k.c.
370+ [Parvatha] Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c.
371* [Parvatha] Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c.
372+ [Parvatha] Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
373+ [Parvatha] Structure T2_MODE. This tells if the t2_encode_packets() is called during Threshold calculation or in Final pass. Modification in j2k.h, tcd.c
375March 30, 2007
376* [GB] OPJViewer should now work under Linux, at least with not big j2k files. Tested under Suse 10.1 64 bit.
378March 29, 2007
379* [Parvatha] Enable accepting file names with `-´ symbol .Modification getopt.c
380* [Parvatha] Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c
381! [Parvatha] renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c
382* [Parvatha] Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c
383! [Parvatha] j2k_setup_encoder to set bit rate limitation for digital cinema compliance with quality option. Modification in j2k.c
384* [Parvatha] Equation to check multiple tile precincts. Modification pi.c
385! [Parvatha] array size generation of pi->include in pi_initialise_encode().Modification in pi.c
386* [Parvatha] modification in pi_create_encode for tile part generation.Modification in pi.c
387+ [Parvatha] In tcd_rateallocate a variable stable_threshold which holds the valid threshold value.

390March 28, 2007
391* [FOD] Fixed an historical bug in t1.c that leaded to the inclusion of useless 0xFF in the codestream. Thanks to Sylvain, Pascal and Parvatha !
393March 27, 2007
394+ [GB] Improved parsing in OPJViewer, as well some minor aesthetic modifications; support for image rendering with bit depths lower than 8 bits; 
395		can display an arbitrary frame of an MJ2 file (only in B/W, though); can reload a file; better resizing capabilities
396* [GB] Following to Hervé's suggestions, all the exit() calls, added by JPWL strict checking in t2.c and j2k.c, 
397		have been substituted with (object free'ing + opj_evt_message(EVT_ERROR) + return)
