Francois-Olivier Devaux 9e5d165e79 Fixed the maximum number of resolutions a user can discard while decoding.
Added an error state in J2K_STATE (j2k.c)
2007-11-27 14:00:45 +00:00
Francois-Olivier Devaux 3816e0edf4 Indexes can now be generated when decoding J2K codestreams. 2007-09-07 15:01:55 +00:00
Giuseppe Baruffa 564e16d5ce Added the knowledge of JPSEC SEC and INSEC markers (you have to compile the JPWL project). Management of these markers is limited to skipping them without crashing: no real security function at this stage. Deprecated USE_JPSEC and USE_JPWL will be removed next 2007-09-03 13:30:59 +00:00
Francois-Olivier Devaux acfe0ad645 Changed the OpenJPEG library interface to enable users to access information regarding the codestream (also called index). 2007-08-30 09:51:20 +00:00

Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c.
Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c.
Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
Structure T2_MODE. This tells if the t2_encode_packets() is called during Threshold calculation or in Final pass. Modification in j2k.h, tcd.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.

Parvatha Elangovan 78003a016a Added option for Digital cinema profile compliant codestream. This can be chosen by "-cinema2K" or "-cinema4K" for a 2K and 4K compliance respectively. The feature for tileparts has not been implemented in this version. Modification in image_to_j2k.c
Added the Digital Cinema profiles (CINEMA2K and CINEMA4K) to the list of profiles recognized in the codestream SIZ marker segment. Modification in openjpeg.h,j2k.c
Added feature for constant quality within bitrate defined in Digital cinema standards. Modification in tcd.c
Modified the method of generation of buffer length. Modification in cio.c

Antonin Descampe b565431251 added the ability to specify the rate as "float" (before : integer) 2006-10-31 17:10:14 +00:00
Antonin Descampe 95bc884365 OpenJPEG version 1.1 2005-12-08 09:38:47 +00:00
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 8f3bd54c3d Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double

(thanks to Stefano Pensa)
2004-11-29 14:48:20 +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!)
2004-08-06 14:13:51 +00:00
Antonin Descampe 55e5910d6b * PPM markers handling modified (comment keyword : ppmbug1)
* empty resolution level or subband handling (comment keyword : sizebug1)
* index_on field forwarded to j2k_cp_t structure

Antonin Descampe 275b153fc2 small changes in the INDEX-file generation (in order to only use data from index data structures) 2004-05-07 14:41:45 +00:00
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]}

foreach tile {
  tileno start_pos end_header end_pos squarred_error_total nb_pixels mean_squarred_error
}
foreach tile {
  foreach packet {

}
