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.

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)

Patch from Callum Lewick. Memset patch. See ChangeLog for more details. Thanks Callum !

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 !

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 plateform)

OpenJPEG library interface modified to retain compatibility with version 1.2. Sorry if some of you already adapted their code to the previous interface, but we want to avoid a ABI break....

Fixed issues with cstr_info when codestream has components with different number of resolutions.

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.

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

Indexes can now be generated when decoding J2K codestreams.

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
2007-09-06 15:59:39 +00:00

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.
2007-09-04 14:19:55 +00:00
564e16d5ce
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 and USE_JPWL will be removed next
2007-09-03 13:30:59 +00:00
7a2d96efe1
Added information regarding the end of packet position in the index

Replaced the large ctxno_mag lookup table with a small bit of inline-able branchless code

Consolidated some calls to mqc_setcurctx. Cleaned up t1_generate_luts to output the proper types.
2007-08-21 12:36:05 +00:00
d4d23c7eb5
Reworks of t1_updateflags to get rid of the shift operation. mqc_setcurctx moved to the header to allow it to be inlined into the t1.

Minor cleanup patch, that gets rid of a bunch of "old style declaration" warnings from Intel's compiler

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)
2007-07-12 08:31:01 +00:00

fixed the size of the memory allocation in cio.c (confusion between bits and bytes)

ea9335ff48
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).
2007-06-04 13:23:26 +00:00
1f55aaf4a6
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.

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"
2007-05-22 13:14:13 +00:00
1bec8fe082
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."
2007-05-21 13:08:10 +00:00
7d06d7fb5d
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."
2007-05-21 12:50:03 +00:00
e0ee9becb4
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."

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.

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.
