| 2017-06-21 | dwt.c: implement SSE2 idwt5x3 horizontal when len is multiple of 8. Speed ↵opj_idwt53_h_cas0_SSE2 | Even Rouault | |
| gain is very marginal however | |||

| 2017-06-20 | Improve performance of inverse DWT 5x3 (#953) | Even Rouault | |
| * Use single-pass lifting inverse wavelet transform. * For vertical pass, use SSE2 when available so as to process 8 columns in parallel. This is the most beneficial improvement, since the vertical pass involves a lot of cache trashing. With the bench_dwt utility with default arguments (16383x16383 image), time goes from 4.064 s to 1.212 s. | |||
| 2017-06-20 | Add bench_dwt program (compiled only if BUILD_BENCH_DWT=ON) | Even Rouault | |
| 2017-06-17 | Remove OPJ_NOSANITIZE in opj_bio_read() and opj_bio_write() (#761) | Even Rouault | |
| Commit 29313eb5 introduced those flags to avoid issues with -fsanitize=unsigned-integer-overflow However it is better just to rewrite the loop to avoid such condition to occur. | |||

| 2017-06-12 | Packet header writing: set empty packet header bit to 0 when appropriate ↵fix_bypass_pterm_termall_and_lossless_decomposition_issue | Even Rouault | |
| (small optimization) | |||
| 2017-06-12 | Encoder: fix packet writing of empty sub-bands (#891, #892) | Even Rouault | |
| There are situations where, given a tile size, at a resolution level, there are sub-bands with x0==x1 or y0==y1, that consequently don't have any valid codeblocks, but the other sub-bands may be non-empty. Given that we recycle the memory from one tile to another one, those ghost codeblocks might be non-0 and thus candidate for packet inclusion. | |||
| 2017-06-09 | T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes. (#674)fix_bypass_pterm_termall | Even Rouault | |
| There were a number of defects regarding when and how the termination of passes had to done and the computation of their rate. | |||
| 2017-06-02 | opj_t1_dec_sigpass_raw/opj_t1_dec_refpass_raw: harmonize style with mqc methods | Even Rouault | |
| 2017-06-02 | MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. | Even Rouault | |
| This saves comparing the current pointer with the end of buffer pointer. This results at least in tiny speed improvement for raw decoding, and smaller code size for MQC as well. This kills the remains of the raw.h/.c files that were only used for decoding. Encoding using the mqc structure already. | |||
| 2017-06-02 | Fix documentation of opj_t1_decode_cblks() | Even Rouault | |
| 2017-06-02 | Simplify VSC handling: instead of masking out bits when reading the 4th row. | Even Rouault | |
| Do not set them when updating flags of the 1st row | |||

| 2017-06-02 | T1: remove use of neghalf variable. It is useless since bpno is always > 0 | Even Rouault | |

| 2017-05-23 | T1: use more compact flags to optimize cache usage in encoder passes. (#172) | Even Rouault | |
| Ported from Carl Hetherington work (actually through Matthieu Darbois's port on top of OpenJPEG 2.1.0) Can reduce total encoding time by 10-15% WARNING: VSC mode is not implemented, and so is a temporary regression that must be fixed. | |||

| 2017-05-09 | Reformat whole codebase with astyle.options (#128) | Even Rouault | |
| 2017-02-13 | Remove warnings related to empty tag-trees. | Even Rouault | |
| Decoding some valid .jp2 files like Sentinel2 datasets leads to warnings like: No incltree created. tgt_create tree->numnodes == 0, no tree created. No imsbtree created. tgt_create tree->numnodes == 0, no tree created. Besides that, the image is correctly decoded. So there is no reason to emit those warnings. | |||

| 2016-09-21 | Fix some issues reported by Coverity Scan (#846) | Stefan Weil | |
| * test_tile_decoder: Fix potential buffer overflow (coverity) CID 1190155 (#1 of 1): Unbounded source buffer (STRING_SIZE) Using a pointer instead of buffer of fixed size avoids the limit for the length of the input file name. Signed-off-by: Stefan Weil <sw@weilnetz.de> * test_tile_encoder: Fix potential buffer overflow (coverity) CID 1190154 (#1 of 1): Unbounded source buffer (STRING_SIZE) Using a pointer instead of buffer of fixed size avoids the limit for the length of the output file name. This implies that the length can exceed 255, so the data type for variable len had to be fixed, too.
