2007-11-05Fixed 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)
2007-10-18Patch from Callum Lewick. Memset patch. See ChangeLog for more details. ↵Francois-Olivier Devaux
Thanks Callum !
2007-10-12Changed 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
2007-09-27Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was ↵Francois-Olivier Devaux
problematic under x86_64.
2007-09-25BUG: 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)
2007-09-19Fixed issues with generation of SOP marker.Parvatha Elangovan
2007-09-18Fixed 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.
2007-09-17OpenJPEG 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....
2007-09-17Fixed issues with cstr_info when codestream has components with different ↵Francois-Olivier Devaux
number of resolutions.
2007-09-12Patch 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.
2007-09-11JPWL 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
2007-09-07Indexes can now be generated when decoding J2K codestreams.Francois-Olivier Devaux
2007-09-06One 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
2007-09-04Added 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.
2007-09-03Added 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
2007-08-30Added information regarding the end of packet position in the index Francois-Olivier Devaux
2007-08-30Changed the OpenJPEG library interface to enable users to access information ↵Francois-Olivier Devaux
regarding the codestream (also called index).
2007-08-28Fixed wrong destructors called in openjpeg.cFrancois-Olivier Devaux
Fixed bug in j2k_decode_jpt_stream
2007-08-24The end of main header is calculated after TLM and POC marker for Dcinema.Parvatha Elangovan
2007-08-24Fixed problem with _mm_malloc under OSX. Thanks to Callum Lerwick for ↵Francois-Olivier Devaux
solving that issue.
2007-08-21Use <xmmintrin.h> for WIN32, else use <mm_malloc.h> Francois-Olivier Devaux
2007-08-21Moved the orient flipping into the ctxno_zc table.Francois-Olivier Devaux
Thanks to Callum Lerwick who provided all these great patches !
2007-08-21Replaced the large ctxno_mag lookup table with a small bit of inline-able ↵Francois-Olivier Devaux
branchless code
2007-08-21Consolidated some calls to mqc_setcurctx. Cleaned up t1_generate_luts to ↵Francois-Olivier Devaux
output the proper types.
2007-08-21Reworks 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.
2007-08-21Memory leaks fixedFrancois-Olivier Devaux
2007-08-21Aligned malloc using Intel's _mm_malloc(), cleanup on the t1 memory ↵Francois-Olivier Devaux
allocation, getting rid of some leftover debug code
2007-08-21Minor cleanup patch, that gets rid of a bunch of "old style declaration" ↵Francois-Olivier Devaux
warnings from Intel's compiler
2007-08-21Corrected allocation to take into account the EOC markerFrancois-Olivier Devaux
2007-08-08Fixed the DCinema filesize allocation. It now includes the SOT marker sizeFrancois-Olivier Devaux
2007-07-13(no commit message)Francois-Olivier Devaux
2007-07-12Fixed a bug in JPWL module, which prevented to exploit the full error ↵Giuseppe Baruffa
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)
2007-07-08fixed the size of the memory allocation in cio.c (confusion between bits and ↵Antonin Descampe
bytes)
2007-06-21Output image color space set when decoding a JP2 fileFrancois-Olivier Devaux
2007-06-15Fixed the generation of index files. Now works with cinema formats. Francois-Olivier Devaux
2007-06-04Release of version 1.2.0Francois-Olivier Devaux
2007-06-04Bugs corrected in decoding of command line (getopt.c), in the handling of 16 ↵Francois-Olivier Devaux
bit files (t1.c and tcd.c) and the calculation of elapsed time for multiple tiles parts (tcd.c and tdc.h).
2007-05-23Bug fixed by Sylvain Munaut. Change in the reading of the POC marker. Since ↵Francois-Olivier Devaux
COD/COC can be anywhere in the header, the decoder cannot always know while decoding the POC marker the value of numlayers and numresolution.
2007-05-22Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data ↵Francois-Olivier Devaux
arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts"
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting ↵Francois-Olivier Devaux
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."
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "This changes the flag ↵Francois-Olivier Devaux
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."
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 ↵Francois-Olivier Devaux
LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely."
2007-05-10MJ2 codec updated from LibOpenJPEG version 0.97 to LibOpenJPEG version 1. ↵Francois-Olivier Devaux
Hence, the MJ2 codec will now take advantage of all the improvements and optimizations done on the LibOpenJPEG library.
2007-05-10Possibility to choose to apply MCT (multiple component transform) enabled, ↵Francois-Olivier Devaux
and new decoding_limit: DECODE_ALL_BUT_PACKETS
2007-04-25Modification of the openjpeg.h file to avoid and ABI break with v1.1, ↵Francois-Olivier Devaux
removed the dangerous #IFDEF JPWL and added tcp_mct in cparameters.
2007-04-10Accepting "j2c" as format for Encoding and Decoding. Modification in ↵Parvatha Elangovan
image_to_j2k.c. Modified imagetotif() to read images with signed data. Modification in convert.c.
2007-04-05fix.h, dwt.c and t1.c optimized. Thanks a lot to Dzonatas <dzonatas at ↵Francois-Olivier Devaux
dzonux.net> and Callum Lerwick <seg at haxxed.com> for these great patches !
2007-04-04Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification ↵Parvatha Elangovan
in image_to_j2k.c. Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c. Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c. Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c. 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
2007-03-29Enable accepting file names with `-´ symbol .Modification getopt.cParvatha Elangovan
Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c Renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c j2k_setup_encoder to set bit rate limitation for digital cinema compliance with quality option. Modification in j2k.c Equation to check multiple tile precincts. Modification pi.c array size generation of pi->include in pi_initialise_encode().Modification in pi.c Modification in pi_create_encode for tile part generation.Modification in pi.c In tcd_rateallocate a variable stable_threshold which holds the valid threshold value. This is used to avoid error in case of a wrong threshold value in the last iteration. Modification in tcd.c.
