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.
2007-03-28Fixed an historical bug in t1.c that leaded to the inclusion of useless 0xFF ↵Francois-Olivier Devaux
in the codestream. Thanks to Sylvain, Pascal and Parvatha !
2007-03-27Following to Hervé's suggestions, all the exit() calls, added by JPWL ↵Giuseppe Baruffa
strict checking in t2.c and j2k.c, have been substituted with (object free'ing + opj_evt_message(EVT_ERROR) + return); added linking to TIFF library in the JPWL VC6 workspaces
2007-03-21Fixed j2k_prog_order_list[]. Modifications in j2k.c.Parvatha Elangovan
Fixed t1_decode_cblks. Modifications in t1.c.
2007-03-20Added feature for generation of tile parts. Modifications in image_to_j2k.c, ↵Parvatha Elangovan
openjpeg.c, j2k.c, pi.c Added function j2k_write_tlm(),to generate TLM marker for a Digital cinema compliant codestream. Modifications in j2k.c.
2007-03-07Added option for Digital cinema profile compliant codestream. This can be ↵Parvatha Elangovan
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 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 Added feature for constant quality within bitrate defined in Digital cinema standards. Modification in tcd.c Modified the method of generation of buffer length. Modification in cio.c
2007-02-28Enabled compression of TIF image format to j2k by tifftoimage() and ↵Parvatha Elangovan
decompression of codestream to TIF image format using imagetotif(). Modifications in image_to_j2k.c, j2k_to_image.c, convert.c, convert.h
2007-02-28fixed a bug in context numerotation that prevented the RESET switch to work ↵Antonin Descampe
correctly : mqc_reset_enc in mqc.c
2007-02-23Changed version number from 1.1.0 to 1.1.1 in openjpeg.hFrancois-Olivier Devaux
2007-02-23Fixed a copy-and-paste type assignment error (bool instead of int) in the ↵Giuseppe Baruffa
JPWL section of decoder parameters structure in openjpeg.h; minor type-casting in jpwl_lib.c. As a result, now OPJViewer should run correctly when built against the most current SVN trunk of LibOpenJPEG.lib
2007-02-21Algorithmic optimizations in t1.c, thanks to Guido J. !Francois-Olivier Devaux
2007-02-19Added OPJ_LIMIT_DECODING enabling us to limit the decoding to main headerFrancois-Olivier Devaux

and image_to_j2k.c -> no more warnings in linux compilation
2007-01-30Use of OPJ_PATH_LEN (defined as 4096) to be the maximum allowed size for ↵Francois-Olivier Devaux
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
2007-01-23Modification of the context numbers, to reflect what has been specified in ↵Francois-Olivier Devaux
standard.
