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

c458af9cd6 Avoided ABI breakage 2007-11-14 11:34:48 +00:00

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

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

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

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

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

9e114bcaa4 Patch from Callum Lewick. Memset patch. See ChangeLog for more details. Thanks Callum ! 2007-10-18 12:26:11 +00:00

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 !

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

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

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

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

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). 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

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
