Even Rouault 68832af20e opj_tcd_dc_level_shift_decode: avoid int32 overflow when prec == 31. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2799. Credit to OSS Fuzz 2017-07-30 15:22:24 +02:00

Even Rouault 820fcfe8bb opj_j2k_update_image_data / opj_tcd_update_tile_data: fix unaligned load/store (#895)
When components don't have the same width, unaligned load/store are possible.

Fixes openjeg-crashes-2017-07-27/id:000000,sig:11,src:001342,op:flip4,pos:162.jp2 of #895

Even Rouault 94c4b7300c T1 decoder: check code stream errors when predictable termination is enabled and emit a warning when errors are found 2017-07-26 21:43:32 +02:00
Even Rouault 9cbc9903c3 Merge branch 't1_flag_optimizations' 2017-06-13 12:09:52 +02:00
Even Rouault 73d1510d47 Encoder: fix packet writing of empty sub-bands (#891, #892)
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.

Even Rouault 81c5311758 T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes. (#674)
There were a number of defects regarding when and how the termination of
passes had to done and the computation of their rate.

Even Rouault 532243f1fd MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker.
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.

Even Rouault 563bd8499e Reformat whole codebase with astyle.options (#128) 2017-05-09 20:46:20 +02:00
Even Rouault a43f1bea62 Remove warnings related to empty tag-trees.
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.

Coordinates are casted from OPJ_UINT32 to OPJ_INT32
Add sanity check for negative values and upper bound becoming lower
than lower bound.

Even Rouault d4b7f03cfa Add opj_codec_set_threads() in public API and propagate resulting thread pool to tcd level
By default, only the main thread is used. If opj_codec_set_threads() is not used,
but the OPJ_NUM_THREADS environment variable is set, its value will be
used to initialize the number of threads. The value can be either an integer
number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called,
this function will override the behaviour of the environment variable.

Matthieu Darbois e6881e7527 Fix negative shift left reported by UBSan (#758)
Follow-up of #757

This shall have no performance impact on 2’s complement machine where
the compiler replaces the multiplication by power of two (constant) by
a left shift.
Verified at least on MacOS Xcode 7.3, same assembly generated after fix.
