openjpeg/libopenjpeg, branch version.1.2 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=version.1.2 2007-06-04T13:27:25Z Release of version 1.2.0 2007-06-04T13:27:25Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-06-04T13:27:25Z urn:sha1:21f2cab7103d7a4e502aa58d88218c21c97b48fb 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). 2007-06-04T13:23:26Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-06-04T13:23:26Z urn:sha1:ea9335ff48f106556e04a249d88246dba493a62a 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. 2007-05-23T16:04:50Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-23T16:04:50Z urn:sha1:1f55aaf4a61face93c4e6d5bee95c18ec08c8172 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" 2007-05-22T13:14:13Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-22T13:14:13Z urn:sha1:8be8111008f87f643cafde4d5204d8146786b140 Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting cleanups, so that the long function definitions and calls fit on screen.

Consolidation of some redundant calculations in the inner loops, which becomes very useful in the future autovectorize patch." 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." 2007-05-21T12:50:03Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-21T12:50:03Z urn:sha1:7d06d7fb5db82318686bad0b99951d6d612f6cca 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." 2007-05-21T09:44:10Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-21T09:44:10Z urn:sha1:e0ee9becb44885136be01e15fa4feaf75478b19b 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. 2007-05-10T14:21:09Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-10T14:21:09Z urn:sha1:1200dd871a3f39d8b7367f3bcbeb2d144c38369a Possibility to choose to apply MCT (multiple component transform) enabled, and new decoding_limit: DECODE_ALL_BUT_PACKETS 2007-05-10T14:13:30Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-10T14:13:30Z urn:sha1:f3170bf64e39a9f9d512adde7e7b315f156fed8e 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. 2007-04-25T17:04:21Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-04-25T17:04:21Z urn:sha1:2bd0f7b8c47a6406f5f71a1b35647cfc3f5803fc
