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

tile_width tile_height
nb_tiles_width nb_tiles_height
nb_components
