Antonin Descampe 7caaea18b7 Deleting obsolete files and directories, adding v2-specific files and directories, updating existing files to v2. See README.v2 for more info 2008-07-31 18:47:41 +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 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
Parvatha Elangovan 9ba672366e Enable accepting file names with `-´ symbol .Modification getopt.c
Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c
Renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c
Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c
j2k_setup_encoder to set bit rate limitation for digital cinema compliance with quality option. Modification in j2k.c
Equation to check multiple tile precincts. Modification pi.c
array size generation of pi->include in pi_initialise_encode().Modification in pi.c
Modification in pi_create_encode for tile part generation.Modification in pi.c
In tcd_rateallocate a variable stable_threshold which holds the valid threshold value. This is used to avoid error in case of a wrong threshold value in the last iteration. Modification in tcd.c.

Antonin Descampe f61cda9b7d openjpeg version 1.0 (previous version still available with tag opj0-97) 2005-12-02 13:34:15 +00:00
Antonin Descampe 7ee36c3a4c 1) quantization stepsizes stored as float instead of shifted integers -> fixes a pb of precision when using very small stepsizes. 2) bug fixed when decoding until bitplane 0 -> r-value (1/2) added to the coefficient. 2005-10-27 07:49:29 +00:00
Antonin Descampe bc5c5115cb * Inserted tool for memory leaks fixing in debug mode
* Fixed some memory leaks in the decoder (some are still present when multiple tiles!)

Antonin Descampe bc563fc5ba * Quantization bug fixed when using 9x7 DWT (comment keyword : quantizbug1)
* Multiplication bug fixed when dividing by 8192 (comment keyword : multbug1)

Antonin Descampe a4911967eb * Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the command line when encoding an image generates layers with the corresponding psnr. You have to specify values in the increase order. This option is incompatible with "-r" or "-f" options.
* Old -q option is now available with -f

* The INDEX-file structure has been modified and is now like this :
------------------------------
image_width image_height
progression order
tile_width tile_height
nb_tiles_width nb_tiles_height
nb_components
nb_layers
nb_decompositions
foreach resolution_level {[precinct_width,precinct_height]}
