openjpeg/libopenjpeg/tcd.c, branch v2 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=v2 2009-09-10T13:34:19Z V2 branch : 2009-09-10T13:34:19Z Antonin Descampe antonin@gmail.com 2009-09-10T13:34:19Z urn:sha1:ec400c4fa5ed89b85b3694f6424dda2541d25c0b - found a bug in tcd.c that was preventing to find the correct threshold in tcd_rateallocate.c for high-precision images. Applied a temporary patch but a better solution should be found. - Modified the way raw images with more that 8bpp are read and written Deleting obsolete files and directories, adding v2-specific files and directories, updating existing files to v2. See README.v2 for more info 2008-07-31T18:47:41Z Antonin Descampe antonin@gmail.com 2008-07-31T18:47:41Z urn:sha1:7caaea18b728ead4e45226aafc09dba01e514a2d In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, corrected Rate modification in tcd_init_encode(). 2008-02-05T15:15:38Z Parvatha Elangovan p.elangovan@intopix.com 2008-02-05T15:15:38Z urn:sha1:29ea3dde47818da3eecb917ebb1db797a3e80d44 Patch by Callum Lerwick.

Thank you Patrick for this new module ! 2007-12-10T13:16:01Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-12-10T13:16:01Z urn:sha1:26606c71c8a5c3a79f9e371e1c0ddfcb800b77df Fixed the maximum number of resolutions a user can discard while decoding. 2007-11-27T14:00:45Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-11-27T14:00:45Z urn:sha1:9e5d165e79499cffe11a85ebc1b1ff320d52953b Added an error state in J2K_STATE (j2k.c) 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. 2007-11-14T10:52:02Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-11-14T10:52:02Z urn:sha1:010ae27471655e3fe05912bd9965245a4f2cd7f3 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. 2007-11-14T08:45:00Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-11-14T08:45:00Z urn:sha1:24e189e4d8a231e7273d788b2bd77e2484cec761 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. 2007-11-13T17:35:12Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-11-13T17:35:12Z urn:sha1:dbeebe72b9d35f6ff807c21c7f217b569fa894f6
