  • efa5f7977c Created the file index.c in the codec directory. This file handles the creation of index files, at encoding and decoding. Fixed bugs during the creation of the index (PCRL progression order) Francois-Olivier Devaux 2007-11-27 12:38:52 +0000
  • c458af9cd6 Avoided ABI breakage Francois-Olivier Devaux 2007-11-14 11:34:48 +0000
  • 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. Francois-Olivier Devaux 2007-11-14 10:52:02 +0000
  • 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. Francois-Olivier Devaux 2007-11-14 08:45:00 +0000
  • 61a15672bb Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c Francois-Olivier Devaux 2007-11-14 08:29:12 +0000
  • 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. Francois-Olivier Devaux 2007-11-13 17:35:12 +0000
  • 014694b04f BUG: Fix name of project Mathieu Malaterre 2007-11-08 14:52:45 +0000

  • 5fdc05d18d Changed the ROI parameter in the image_to_j2k codec to make it correspond to the documentation (i.e. -ROI c=0,U=25) Francois-Olivier Devaux 2007-10-18 08:14:43 +0000
  • 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 !

  • 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) Giuseppe Baruffa 2007-07-12 08:31:01 +0000

  • 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. Francois-Olivier Devaux 2007-05-23 16:04:50 +0000
  • 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" Francois-Olivier Devaux 2007-05-22 13:14:13 +0000
  • 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." Francois-Olivier Devaux 2007-05-21 13:08:10 +0000
  • 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." Francois-Olivier Devaux 2007-05-21 12:50:03 +0000
  • 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." Francois-Olivier Devaux 2007-05-21 09:44:10 +0000
