| 2007-06-04 | Bugs corrected in decoding of command line (getopt.c), in the handling of 16 ↵ | Francois-Olivier Devaux | |
| bit files (t1.c and tcd.c) and the calculation of elapsed time for multiple tiles parts (tcd.c and tdc.h). | |||
| 2007-05-22 | Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data ↵ | Francois-Olivier Devaux | |
| arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts" | |||
| 2007-05-21 | Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting ↵ | Francois-Olivier Devaux | |
| cleanups, so that the long function definitions and calls fit on screen. Use of prefix increment which is theoretically faster, in practice any sane compiler can optimize a postfix increment but its best not to count on such things. Consolidation of some redundant calculations in the inner loops, which becomes very useful in the future autovectorize patch." | |||
| 2007-05-21 | Patch suggested by Callum Lerwick <seg@haxxed.com>: "This changes the flag ↵ | Francois-Olivier Devaux | |
| code in t1 to use a flag_t type, which can then be changed to reduce RAM usage. It is now typedef to a short." | |||
| 2007-05-21 | Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 ↵ | Francois-Olivier Devaux | |
| LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely." | |||
| 2007-04-05 | fix.h, dwt.c and t1.c optimized. Thanks a lot to Dzonatas <dzonatas at ↵ | Francois-Olivier Devaux | |
| dzonux.net> and Callum Lerwick <seg at haxxed.com> for these great patches ! | |||
| 2007-03-28 | Fixed an historical bug in t1.c that leaded to the inclusion of useless 0xFF ↵ | Francois-Olivier Devaux | |
| in the codestream. Thanks to Sylvain, Pascal and Parvatha ! | |||
| 2007-03-21 | Fixed j2k_prog_order_list[]. Modifications in j2k.c. | Parvatha Elangovan | |
| Fixed t1_decode_cblks. Modifications in t1.c. | |||
| 2007-02-21 | Algorithmic optimizations in t1.c, thanks to Guido J. ! | Francois-Olivier Devaux | |
| 2007-01-15 | Copyright update | Francois-Olivier Devaux | |
| 2006-03-19 | fixed a bug in t1.c that prevented in some cases a true lossless compression ↵ | Antonin Descampe | |
| (thanks to Don Mimlitch for reporting this bug) | |||
| 2006-01-27 | fixed two initialization problems in t1.c and tcd.c | Antonin Descampe | |
| 2005-12-08 | fixed a bug in t1_getwmsedec (stepsize was divided by 8192) | Antonin Descampe | |
| 2005-12-08 | OpenJPEG version 1.1 | Antonin Descampe | |
| 2005-12-02 | openjpeg version 1.0 (previous version still available with tag opj0-97) | Antonin Descampe | |
| 2005-11-04 | small change to avoid signed/unsigned warning during compilation | Antonin Descampe | |
| 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. | |||
| 2005-06-02 | At lines 577, 692 and 699, zeroing of effective region of code-block rather ↵ | Francois-Olivier Devaux | |
| than the 1024*1024 allocated integers of code-block. This optimization has been proposed by Dmitry Kolyadin. Thanks for your help ! | |||
| 2005-05-24 | Code optimization: t1_flags and t1_data set to zero with memset | Francois-Olivier Devaux | |
| 2004-11-15 | fprintf correctly redirected to stderr or stdout | Francois-Olivier Devaux | |
| 2004-07-16 | Minor changes for RESET mode | Antonin Descampe | |
| 2004-07-13 | * Quantization bug fixed when using 9x7 DWT (comment keyword : quantizbug1) | Antonin Descampe | |
| * Multiplication bug fixed when dividing by 8192 (comment keyword : multbug1) | |||
| 2004-05-07 | * Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the ↵ | Antonin Descampe | |
| 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 ----------------------------- | |||
