Francois-Olivier Devaux 1a33a09726 In mqc.h, changed MQC_NUMCTXS from 32 to 19 as JPEG 2000 only allows 19 possible contexts 2007-12-19 09:13:52 +00:00
Francois-Olivier Devaux 26606c71c8 First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis (www.telemis.com). Thank you Patrick for this new module ! 2007-12-10 13:16:01 +00:00

Francois-Olivier Devaux c458af9cd6 Avoided ABI breakage 2007-11-14 11:34:48 +00:00
Francois-Olivier Devaux 010ae27471 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. 2007-11-14 10:52:02 +00:00
Francois-Olivier Devaux 24e189e4d8 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. 2007-11-14 08:45:00 +00:00
Francois-Olivier Devaux 61a15672bb Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c 2007-11-14 08:29:12 +00:00
Francois-Olivier Devaux dbeebe72b9 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. 2007-11-13 17:35:12 +00:00
Francois-Olivier Devaux 4bb067642f Patches from Callum Lewick: Fixed some spelling errors in dwt.c. 2007-11-08 14:29:39 +00:00
Francois-Olivier Devaux c38de0728d In t1.c, small change to avoid calling twice t1_getwmsedec() 
Patch from Callum Lewick. Basic gcc optimization flags in cmake and makefile match.
 2007-11-08 14:26:03 +00:00
Giuseppe Baruffa 95d760a173 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) 2007-11-05 13:05:07 +00:00
Francois-Olivier Devaux 9e114bcaa4 Patch from Callum Lewick. Memset patch. See ChangeLog for more details. Thanks Callum ! 2007-10-18 12:26:11 +00:00
Francois-Olivier Devaux 1f11a4fe90 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 !
 2007-10-12 15:04:34 +00:00
Francois-Olivier Devaux ab0473aa42 *Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff. 
*convert.c: Changed some error comments for TIFF images
 2007-10-10 06:17:28 +00:00
Francois-Olivier Devaux 4b60f17bba Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64. 2007-09-27 12:20:12 +00:00
Mathieu Malaterre 6265dcfb11 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) 2007-09-25 14:54:49 +00:00

Francois-Olivier Devaux 55c4c14352 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.... 2007-09-17 15:11:20 +00:00
Francois-Olivier Devaux 569bbb0077 Fixed issues with cstr_info when codestream has components with different number of resolutions. 2007-09-17 14:00:43 +00:00
Francois-Olivier Devaux abfba20b99 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. 2007-09-12 09:04:03 +00:00
Giuseppe Baruffa 1e705438e4 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 2007-09-11 15:21:12 +00:00
Francois-Olivier Devaux 3816e0edf4 Indexes can now be generated when decoding J2K codestreams. 2007-09-07 15:01:55 +00:00
Giuseppe Baruffa dfcacb8247 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
Giuseppe Baruffa d3d2a36fbc 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
Giuseppe Baruffa 564e16d5ce Added the knowledge of JPSEC SEC and INSEC markers (you have to compile the JPWL project).

Thanks to Callum Lerwick who provided all these great patches !
 2007-08-21 12:51:57 +00:00
Francois-Olivier Devaux 2952874cb8 Replaced the large ctxno_mag lookup table with a small bit of inline-able branchless code 2007-08-21 12:42:55 +00:00
Francois-Olivier Devaux 1cfbdcc9ce Consolidated some calls to mqc_setcurctx. Cleaned up t1_generate_luts to output the proper types. 2007-08-21 12:36:05 +00:00
Francois-Olivier Devaux 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. 2007-08-21 12:30:08 +00:00
Francois-Olivier Devaux adca52578d Memory leaks fixed 2007-08-21 12:21:35 +00:00

Francois-Olivier Devaux 00e440ebdb Corrected allocation to take into account the EOC marker 2007-08-21 09:06:13 +00:00
Francois-Olivier Devaux 7dcb817e6a Fixed the DCinema filesize allocation. It now includes the SOT marker size 2007-08-08 09:41:16 +00:00
Francois-Olivier Devaux 5dec8bbbe9 2007-07-13 13:07:07 +00:00
Giuseppe Baruffa 4a50efe542 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
Antonin Descampe bdb18ab19c fixed the size of the memory allocation in cio.c (confusion between bits and bytes) 2007-07-08 16:38:51 +00:00
Francois-Olivier Devaux c924975434 Output image color space set when decoding a JP2 file 2007-06-21 08:26:03 +00:00
Francois-Olivier Devaux 3d626da232 Fixed the generation of index files. Now works with cinema formats. 2007-06-15 13:27:43 +00:00
Francois-Olivier Devaux 21f2cab710 Release of version 1.2.0 2007-06-04 13:27:25 +00:00
Francois-Olivier Devaux 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
Francois-Olivier Devaux 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. 2007-05-23 16:04:50 +00:00
Francois-Olivier Devaux 8be8111008 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
