| 2007-04-04 | Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification ↵ | Parvatha Elangovan | |
| in image_to_j2k.c. 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.

| 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.

| 2005-11-01 | Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot ↵ | Antonin Descampe | |
| 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 | |||
| 2005-10-27 | 1) quantization stepsizes stored as float instead of shifted integers -> ↵ | Antonin Descampe | |
| 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. | |||

| 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]} main_header_end codestream_size foreach tile { tileno start_pos end_header end_pos squarred_error_total nb_pixels mean_squarred_error } foreach tile { foreach packet { packetno tileno layerno resno compno precinctno start_pos end_pos SE_reduction } } SE max SE total ----------------------------- | |||
