+
+November 29, 2007
+! [GB] Added index.h and index.c in VC6 projects; wrapped index.h in the C++ preprocessor; modified OPJViewer project and some files.
+
+November 14, 2007
++ [FOD] Created the file index.c in the codec directory. This file handles the creation of index files,
+ at encoding and decoding.
+* [FOD] Fixed bugs during the creation of the index (PCRL progression order)
+* [FOD] Fixed the maximum number of resolutions a user can discard while decoding.
+ Added an error state in J2K_STATE (j2k.c)
+
+November 14, 2007
+! [FOD] - First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
+ - Second Patch by Callum Lerwick. This patch rearranges the largest memory 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.
+ - Third Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest 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.
+
+* [FOD] Avoided ABI breakage
+
+November 13, 2007
+! [FOD] Patch by Dzonatas and Callum Lerwick.
+ Fp/vectorization patch which 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.
+
+November 8, 2007
+! [FOD] In t1.c, small change to avoid calling twice t1_getwmsedec()
+ Patches from Callum Lewick:
+ - Basic gcc optimization flags in cmake and makefile match.
+ - Fixed some spelling errors in dwt.c.
+
+November 5, 2007
+*+ [GB] Fixed a bug which prevented JPWL from working on multi-tiled images; added some more fields in the interface info structures
+(keep a list of markers, save start packet number for each tile)
+
+October 23, 2007
+* [GB] Improved success for the linux build; OPJViewer shows all the COM contents
+
+October 18, 2007
+* [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)
+* [FOD] Patch from Callum Lewick. Memset patch.
+ The main idea of the patch is that currently opj_malloc clears all allocations, which unnecessarily
+ dirties up the cache and eats bandwidth. This patch makes it no longer do so, and I've painstakingly determined which allocations actually need
+ 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
+ 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
+ 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
+ internal headers, but it wasn't using the malloc wrappers. I figured the binaries should be "external" and have minimal knowledge of the
+ internals of the library. I patched them to not include opj_includes.h, and include only the internal headers they actually need. However,
+ 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.
+ 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
+ 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
+ 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.
+
+October 12, 2007
+* [FOD] Changed the way the image structure is allocated when the decoding 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 !
+
+October 10, 2007
+* [FOD] Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff.
+ It makes it work right with mingw, as _mm_malloc() isn't a macro, attempts to pave the way to using cmake
+ to check for this stuff and combines a patch from Dana Fagerstrom at Sun that makes it use memalign() on Solaris
+ convert.c: Changed some error comments for TIFF images
+
+September 27, 2007
+* [FOD] Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64.
+
+September 25, 2007
+* [Mathieu Malaterre] BUG: Fix previous patch from Callum Lerwick. I have no
+ clue what 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 platform)
+
+September 19, 2007
+* [Parvatha] Fixed issues with generation of SOP marker.
+
+September 18, 2007
+* [Parvatha] Fixed issues with Reading and Writing TIF images in convert.c to avoid segmentation fault.
+* [Parvatha] Fixed issues relating to using user specified rates for CINEMA option for multiple images.
+
+September 17, 2007
+* [FOD] Fixed issues with cstr_info when codestream has components with different number of resolutions.
+! [FOD] OpenJPEG library interface modified to retain compatibility with version 1.2
+
+September 12, 2007
+* [FOD] Patch from Callum Lerwick.
+ Fixed the library linking so it links with the 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.
+* [FOD] Updated the MJ2 codec to be compatible with the recent changes in the OpenJPEG library
+
+September 11, 2007
+* [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
+
+September 8, 2007
+* [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
+
+September 7, 2007
++ [FOD] Indexes can now be generated when decoding J2K codestreams.
+* [Mathieu Malaterre] Upon failure, properly return error code (!=0).
+* [Mathieu Malaterre] CMake: Add cmake code to do testing if user has properly setup a testimages directory
+
+September 6, 2007
++ [Mathieu Malaterre] CMake: start compiling mj2, jpwl and jp3d
++ [Mathieu Malaterre] CMake: output all executable/libs into one single directory
++ [Mathieu Malaterre] CMake: start compiling index_create
++ [Mathieu Malaterre] OpenJPEG.rc update copyright year
++ [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.
++ [Mathieu Malaterre] CMake: Add doxygen output
++ [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
++ [Mathieu Malaterre] CMake: Add very simple tests (simply run command line with no option)
+* [Mathieu Malaterre] Fix unitialized read in img_fol (we may need a smarter initialize than memset)
+
+September 4, 2007
++ [GB] Added some fields in the codestream_info structure: they are used to record the position of single tile parts.
+ Changed also the write_index function in the codec, to reflect the presence of this new information.
+
September 3, 2007
-+ [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: no real security function at this stage. Deprecated USE_JPSEC will be removed next

! [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]
* [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]
July 12, 2007
-* [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, even if 6 were correctable); defined a JPWL_MAXIMUM_EPB_ROOM for better customization of the maximum dimension of EPBs (the dimension 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)

May 24, 2007
-* [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 the value of numlayers and numresolution.

! [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"
May 22, 2007
-! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting cleanups, 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 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."
