1 What's New for OpenJPEG
9 * [FOD] Fixed small compatibility issues with win32 in codec (moved include <strings.h>)
12 ! [FOD] Updated makefiles for v1.4 and v2.0
15 * [FOD] Fixed libopenjpeg Makefile
18 ! [FOD] Created a new constant in openjpeg.h to differentiate the case when the colorspace is not supported by the library and when it is not specified in the codestream. Suggested by Matteo Italia.
21 * [antonin] fixed minor bugs which were triggering warnings at compilation (different signedness, wrong pointer type, etc)
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.
27 ! [FOD] Modified the way raw images with more that 8bpp are read and written
30 * [Mathieu Malaterre] remove INLINE from forward decl. Fix CMakeLists.txt for UNIX platforms

34 ! [antonin] updated XCode project file for mac users.
36 ---------------------------
38 CREATION OF A OPJ V2 BRANCH
39 ---------------------------
42 + [antonin] created a branch for openjpeg version 2. Modifications that have been applied to the trunk after revision 483 should be re-applied on the branch (version 2 has been developed based on revision 483).
45 + [Parvatha] Added the default lossless parameter to opj_set_default_encoder_parameters in openjpeg.c.
48 * [antonin] fixed a bug in dirent.h that prevented codec on Linux Alpha Systems to compile correctly. Thanks to RobinC.
51 * [antonin] fixed a bug in j2k.c (j2k_write_sod) that allowed to get negative rates, thanks zhong1985624 for pointing this.
54 * [antonin] additional test to avoid crash due to invalid image size, patch by Christopher Layne
57 * [antonin] memory leak fixed in openjpeg.c (opj_destroy_cstr_info()), patch by Carsten Juttner
60 + [GB] help line for the -F option in j2k_to_image
63 ! [FOD] Changed Java files copyright in JavaOpenJPEG module
66 * [FOD] Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress()
67 and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev
68 * [FOD] Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(),
69 as apparently memalign() is what is working better for everyone. Patch by Callum.
72 - [FOD] Removed the J2KViewer module, which has been replaced by OPJViewer
73 * [FOD] Fixed the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius
76 * [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
77 ! [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
80 ! [Parvatha] In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, corrected Rate modification in
81 tcd_init_encode(). Thanks to Jeremy Furtek and Jérôme Fimes.
84 ! [GB] In opjviewer, unification of JPEG 2000 family handlers (*.jp2, *.mj2, *.j2k) in a single file
87 ! [FOD] In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order
88 to avoid segfaults when freeing the memory allocated for the coding of bad images.
89 Thanks to Christopher Layne for this improvement.
92 + [antonin] Initial commit of Xcode project directory (XCode 2.5 for macosx)
93 available targets : libopenjpeg (stat and dyn), image_to_j2k, j2k_to_image
96 * [antonin] fixed opj_malloc.h for macosx (bugfix provided by janpeder, thanks)
99 + [FOD] Added missing files to JavaOpenJPEG project (files from Patrick Piscaglia)
102 * [Parvatha] Patch by Callum Lerwick. Fixed bug during encoding using tile option in tcd.c
104 ----------------------
106 VERSION 1.3.0 RELEASED
107 ----------------------
110 * [FOD] Bug fixed by David Bruken. Fixed memory allocation issue in opj_malloc.h
111 ! [FOD] Possible errors in pi_create_encode handled
114 * [Antonin] changed variables names alpha, beta, gamma, delta in dwt.c to avoid re-declarations on Macosx
115 ! [Parvatha] In pi.c, removed the Recursive function pi_check_next_level() and modified the code.
116 * [FOD] Fixed allocation problem in pi.c
119 + [FOD] In mqc.h, changed MQC_NUMCTXS from 32 to 19 as there are only 19 possible contexts
122 + [FOD] First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis (www.telemis.com).
123 Thank you Patrick for this new module !
126 ! [GB] Added index.h and index.c in VC6 projects; wrapped index.h in the C++ preprocessor; modified OPJViewer project and some files.
129 + [FOD] Created the file index.c in the codec directory. This file handles the creation of index files,
130 at encoding and decoding.
131 * [FOD] Fixed bugs during the creation of the index (PCRL progression order)
132 * [FOD] Fixed the maximum number of resolutions a user can discard while decoding.
133 Added an error state in J2K_STATE (j2k.c)
136 ! [FOD] - First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
137 - Second Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as
138 late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.
139 - Third Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it
140 contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates
141 the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size
142 them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate
143 encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.
145 * [FOD] Avoided ABI breakage
148 ! [FOD] Patch by Dzonatas and Callum Lerwick.
149 Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point,
150 eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement,
151 and an increase in accuracy.
154 ! [FOD] In t1.c, small change to avoid calling twice t1_getwmsedec()
155 Patches from Callum Lewick:
156 - Basic gcc optimization flags in cmake and makefile match.
157 - Fixed some spelling errors in dwt.c.
160 *+ [GB] Fixed a bug which prevented JPWL from working on multi-tiled images; added some more fields in the interface info structures
161 (keep a list of markers, save start packet number for each tile)
164 * [GB] Improved success for the linux build; OPJViewer shows all the COM contents
167 * [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)
168 * [FOD] Patch from Callum Lewick. Memset patch.
169 The main idea of the patch is that currently opj_malloc clears all allocations, which unnecessarily
170 dirties up the cache and eats bandwidth. This patch makes it no longer do so, and I've painstakingly determined which allocations actually need
171 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
172 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
173 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
174 internal headers, but it wasn't using the malloc wrappers. I figured the binaries should be "external" and have minimal knowledge of the
175 internals of the library. I patched them to not include opj_includes.h, and include only the internal headers they actually need. However,
176 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.
177 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
178 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
179 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.
182 * [FOD] Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard.
183 This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
184 Warning: The output image size is now reduced when discarding resolutions !
187 * [FOD] Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff.
188 It makes it work right with mingw, as _mm_malloc() isn't a macro, attempts to pave the way to using cmake
189 to check for this stuff and combines a patch from Dana Fagerstrom at Sun that makes it use memalign() on Solaris
190 convert.c: Changed some error comments for TIFF images
193 * [FOD] Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64.
196 * [Mathieu Malaterre] BUG: Fix previous patch from Callum Lerwick. I have no
197 clue what CMAKE_INSTALL_LIBDIR refers too. Bump up cmake 2.2 restriction to
198 cmake 2.4 because of previous patch (not backward compatible). Properly set the SOVERSION in a cross plateform way (yes WIN32 is a platform)
201 * [Parvatha] Fixed issues with generation of SOP marker.
204 * [Parvatha] Fixed issues with Reading and Writing TIF images in convert.c to avoid segmentation fault.
205 * [Parvatha] Fixed issues relating to using user specified rates for CINEMA option for multiple images.
208 * [FOD] Fixed issues with cstr_info when codestream has components with different number of resolutions.
209 ! [FOD] OpenJPEG library interface modified to retain compatibility with version 1.2
212 * [FOD] Patch from Callum Lerwick.
213 Fixed the library linking so it links with the soversion properly set.
214 Fixes up the install targets so that it interacts properly with RPM.
215 Install target for MJ2. Sets some necessary and useful CFLAGS if gcc is in use.
216 * [FOD] Updated the MJ2 codec to be compatible with the recent changes in the OpenJPEG library
219 * [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
222 * [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
225 + [FOD] Indexes can now be generated when decoding J2K codestreams.
226 * [Mathieu Malaterre] Upon failure, properly return error code (!=0).
227 * [Mathieu Malaterre] CMake: Add cmake code to do testing if user has properly setup a testimages directory
230 + [Mathieu Malaterre] CMake: start compiling mj2, jpwl and jp3d
231 + [Mathieu Malaterre] CMake: output all executable/libs into one single directory
232 + [Mathieu Malaterre] CMake: start compiling index_create
233 + [Mathieu Malaterre] OpenJPEG.rc update copyright year
234 + [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.
235 + [Mathieu Malaterre] CMake: Add doxygen output
236 + [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
237 + [Mathieu Malaterre] CMake: Add very simple tests (simply run command line with no option)
238 * [Mathieu Malaterre] Fix unitialized read in img_fol (we may need a smarter initialize than memset)
241 + [GB] Added some fields in the codestream_info structure: they are used to record the position of single tile parts.
242 Changed also the write_index function in the codec, to reflect the presence of this new information.
245 + [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:
246 no real security function at this stage. Deprecated USE_JPSEC will be removed next
249 * [GB] Fixed save capabilities in OPJViewer due to recent code upgrade
252 * [FOD] Changed the OpenJPEG library interface to enable users to access information regarding the codestream (also called codestream index).
253 This index is usefull for all applications requiring to have a scalable acces to the codestream (like JPIP applications, ...)
254 Currently, this information is only available when encoding an image.
255 + [FOD] Added the information regarding the end of packet position in the index
258 * [FOD] Fixed wrong destructors called in openjpeg.c
259 * [FOD] Fixed bug in j2k_decode_jpt_stream
262 * [Parvatha] The end of main header is calculated after TLM and POC marker for Dcinema.
265 + [FOD] Added support for Visual Studio 2005
266 * [FOD] Robustified MJ2 codecs
267 * [Parvatha] Solved problems with codec reading from image file directory when filename had more than one "." in name
268 * [Callum Lerwick] Minor cleanup patch, that gets rid of a bunch of "old style declaration" warnings from Intel's compiler
269 * [Callum Lerwick] Aligned malloc using Intel's _mm_malloc(). Cleanup on the t1 memory allocation, getting rid of some leftover debug code
270 * [Callum Lerwick] Memory leaks fixed
271 * [Callum Lerwick] Reworks of t1_updateflags to get rid of the shift operation
272 * [Callum Lerwick] mqc_setcurctx moved to the header to allow it to be inlined into the t1.
273 * [Callum Lerwick] Consolidated some calls to mqc_setcurctx.
274 * [Callum Lerwick] Cleaned up t1_generate_luts to output the proper types.
275 * [Callum Lerwick] Replaced the large ctxno_mag lookup table with a small bit of inline-able branchless code
276 * [Callum Lerwick] Moved the orient flipping into the ctxno_zc table.
279 + [FOD] Added support for the TGA file format in the codec
282 * [Parvatha] Fixed the DCinema filesize allocation. It now includes the SOT marker size
285 + [GB] Added a basic saving capability to OPJViewer
288 ! [FOD] Updated libtiff library version to 3.8.2 (for WIN32)
289 * [FOD] Updated BMP and PxM truncation when decoding J2K files with more than 8 bits
292 * [FOD] Fixed raw option for images with more than three components
295 + [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]
298 ! [FOD] Modified the memory allocation for codestreams containing multiple tiles. The memory is now allocated for each tile indenpendently,
299 leading to an important decrease of the virtual memory needed. [j2k.c tcd.h tcd.c]
300 ! [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]
301 * [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]
304 * [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,
305 even if 6 were correctable); defined a JPWL_MAXIMUM_EPB_ROOM for better customization of the maximum dimension of EPBs (the dimension
306 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)
309 * [ANTONIN] fixed the size of the memory allocation in cio.c (confusion between bits and bytes)
312 * [FOD] Output image color space set when decoding a JP2 file in jp2.c
313 + [GB] Previous, home, and next frame buttons for exploring MJ2 files in OPJViewer
316 * [GB] Reload image doesn't crash in OPJViewer; more settings saved to registry
319 + [GB] Possibility to disable parsing in OPJViewer; also, saves common settings to the registry
322 * [FOD] Fixed the generation of index files
325 ----------------------
327 VERSION 1.2.0 RELEASED
328 ----------------------
331 * [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).
334 + [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
337 * [FOD] Fixed the handling of 16bit TIFF files for cinema compression. Modified "convert.c"
338 * [FOD] Fixed the parameters used for cinema compression (9-7 transform used instead of 5-3). Modified "image_to_j2k.c"
341 * [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
342 the value of numlayers and numresolution.
345 ! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts"
348 ! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting cleanups,
349 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
350 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."
351 ! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "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."
352 ! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely."
355 - [FOD] JP3D library Binaries removed from SVN.
356 ! [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.
357 ! [FOD] Possibility to choose to apply MCT (multiple component transform) enabled, and new decoding_limit: DECODE_ALL_BUT_PACKETS (openjpeg.h)
360 + [gdcm] Add basic steps on how to use CMake for building examples (README.cmake)
363 + [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.
366 + [GB] Enable/disable image decoding in OPJViewer
369 * [Parvatha] Fixed Error in tiftoimage(). Modification in convert.c.
372 + [Parvatha] Accepting "j2c" as format for Encoding and Decoding. Modification in image_to_j2k.c.

381 + [Parvatha] Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification in image_to_j2k.c.
382 + [Parvatha] Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c.
383 * [Parvatha] Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c.
384 + [Parvatha] Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
385 + [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
388 * [GB] OPJViewer should now work under Linux, at least with not big j2k files. Tested under Suse 10.1 64 bit.
391 * [Parvatha] Enable accepting file names with `-´ symbol .Modification getopt.c
392 * [Parvatha] Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c
393 ! [Parvatha] renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c
394 * [Parvatha] Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c

396 * [Parvatha] Equation to check multiple tile precincts. Modification pi.c
397 ! [Parvatha] array size generation of pi->include in pi_initialise_encode().Modification in pi.c
398 * [Parvatha] modification in pi_create_encode for tile part generation.Modification in pi.c
399 + [Parvatha] In tcd_rateallocate a variable stable_threshold which holds the valid threshold value.
400 This is used to avoid error in case of a wrong threshold value in the last iteration. Modification in tcd.c.
403 * [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 !
406 + [GB] Improved parsing in OPJViewer, as well some minor aesthetic modifications; support for image rendering with bit depths lower than 8 bits;
407 can display an arbitrary frame of an MJ2 file (only in B/W, though); can reload a file; better resizing capabilities
408 * [GB] Following to Hervé's suggestions, all the exit() calls, added by JPWL strict checking in t2.c and j2k.c,
409 have been substituted with (object free'ing + opj_evt_message(EVT_ERROR) + return)
410 + [GB] Added linking to TIFF library in the JPWL VC6 workspaces
413 * [antonin] Fixed Makefile.osx and changed Readme.osx accordingly
416 * [Parvatha] Fixed j2k_prog_order_list[]. Modifications in j2k.c.

424 * [FOD] Fixed linux makefile, with help from David Fries and Guido
427 + [Parvatha] Added option for Digital cinema profile compliant codestream. This can be chosen by "-cinema2K" or "-cinema4K" for a 2K and 4K compliance respectively. The feature for tileparts has not been implemented in this version. Modification in image_to_j2k.c
428 + [Parvatha] Added the Digital Cinema profiles (CINEMA2K and CINEMA4K) to the list of profiles recognized in the codestream SIZ marker segment. Modification in openjpeg.h,j2k.c

430 ! [Parvatha] Modified the method of generation of buffer length. Modification in cio.c
434 * [FOD] Modified codec projects (*.dsp) and makefile to include the tiff library (modified codec/image_to_j2k.dsp codec/j2k_to_image.dsp and codec/makefile)
435 + [GB] Zoom capability and decoder settings dialog in OPJViewer; modified JPWL library .dsp project in order to create a library with embedded JPWL functions
438 + [Parvatha] Enabled compression of TIF image format to j2k by tifftoimage() and decompression of codestream to TIF image format using imagetotif(). Modifications in image_to_j2k.c, j2k_to_image.c, convert.c, convert.h
439 * [antonin] fixed a bug in context numerotation that prevented the RESET switch to work correctly : mqc_reset_enc in mqc.c
440 * [Fod] Corrected codec Makefile by adding the compilation of "compat/getopt.c"
443 * [Parvatha] Made get_file_format function more robust. Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
446 + [Parvatha] Option to read images from a Folder whose path is specified in the Input parameters by "-ImgDir" along with output decod format specified by "-OutFor" . Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
447 + [Parvatha] Enabling use of multi character input parameters in the codec. Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
449 ----------------------
451 VERSION 1.1.1 RELEASED
452 ----------------------
455 * [GB] Fixed a copy-and-paste type assignment error (bool instead of int) in the JPWL section of decoder parameters structure in openjpeg.h; minor type-casting in jpwl_lib.c.
456 As a result, now OPJViewer should run correctly when built against the most current SVN trunk of LibOpenJPEG.lib
457 + [GB] Linux makefile for the JPWL module; newlines at end of JPWL files
460 + [FOD] Added the OPJViewer Module (/OPJViewer), developed by Giuseppe Baruffa of the university of Perugia
463 + [FOD] Algorithmic optimizations in t1.c, thanks to Guido J. !
466 + [FOD] Added OPJ_LIMIT_DECODING enabling us to limit the decoding to main header (modified openjpeg.c, openjpeg.h, j2k.c and j2k.h)
469 ! [FOD] David Fries suggestions. In image_to_j2k and j2k_to_image, strncpy() functions: instead of specifying the path size macro, let the compiler read the length out of the array entry.
470 ! [FOD] David Fries suggestions. Makefile modified. -fPIC flag used for 64-bit compilation. Move operation (rather than copy) for the dist library creation, and -p flag added.
473 ! [FOD] Extra tokens at the end of #endif directive corrected in openjpeg.c, j2k.c and image_to_j2k.c -> no more warnings in linux compilation
474 ! [FOD] Linux Makefile added for the codec
477 ! [FOD] Use of OPJ_PATH_LEN (defined as 4096) to be the maximum allowed size for filenames instead of MAX_PATH which is not always defined. This caused some programs using OpenJPEG to crash. Modifications in openjpeg.h j2k_to_image.c and image_to_j2k.c
478 ! [FOD] Correction of the syntax usage in MJ2_codec/mj2_to_frames.c
481 ! [FOD] Modification in the context numbers, to reflect what has been specified in standard, in libopenjpeg/t1.h
484 + [Giuseppe Baruffa] Antonin verified that the MacOS build suffered from a missing definition of the "min" macro; I've added this definition (properly #ifndef'ed) into both jpwl.h and rs.h
487 * [Giuseppe Baruffa] Better fix of the TPH EPBs bug in JPWL module
488 * [GB] Fixed the UEP bug in JPWL module; now, during a UEP specification, RS protection or CRC check can be switched off for selected range of packets, and consequently reswitched on without confusing the decoder
489 + [GB] Added some lines in the help of JPWL_image_to_j2k, specifying that when using error protection on data packets, this must be paired with header protection, i.e. there cannot be packet protection without header protection
493 + [Francois-Olivier Devaux] New tag: version1.0 (includes codec and libopenjpeg directories)
494 Total update of JPWL module
495 - [FOD] removed directories jpwl/decoder, jpwl/encoder, jpwl/decoder_02, jpwl/encoder_02
