Even Rouault 297f202104 Fix 2.2.0 regression when reading codestream with reperated calls to opj_get_decoded_tile() where tile parts of a same tile are not consecutive 
This check was introduced per #939, but relied on the incorrect assumption
we decode all the tile parts of all tiles.
 2017-09-06 16:49:28 +02:00
Even Rouault 003759a482 Fix null pointer dereference on partial tile decoding when they are empty. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3297 (master only) 2017-09-06 15:59:19 +02:00
Even Rouault e656822f92 Add knownfailures-Ubuntu12.04-gcc4.6.3-x86_64-Release-3rdP.txt 
For some reason, the OPJ_CI_ARCH=x86_64 OPJ_CI_BUILD_CONFIGURATION=Release OPJ_NUM_THREADS=2
configuration fails once PR1010 has been merged in master
( https://travis-ci.org/uclouvain/openjpeg/jobs/272219011 ) whereas (almost) the same
code in my branch didn't fail per https://travis-ci.org/rouault/openjpeg/jobs/271738113

The errors we get are the same as with the other x86_64 compilers, so nothing alarming here.

 2017-09-01 20:02:09 +02:00
Even Rouault 7aa071aa27 opj_j2k_setup_encoder(): emit warnings if tcp_rates are not decreasing or tcp_distoratio are not increasing (#1009) 2017-09-01 19:49:01 +02:00

Even Rouault 09929bb615 opj_compress help: revert 3257261776 and indicate 1 again as being the value to get lossless for -r. In opj_j2k_setup_encoder(), make sure that ll rates[] <= 1.0 are set to 0. Document 0 as being lossless for -q / tcp_distoratio (#1009) 2017-09-01 19:16:35 +02:00

Even Rouault 0ae3cba340 Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images 
* Only works for single-tiled images --> will error out cleanly, as currently
  in other cases
* Save re-reading the codestream for the tile, and re-use code-blocks of the
  previous decoding pass.
* Future improvements might involve improving opj_decompress, and the image writing logic,
  to use this strategy.

Even Rouault 5d07d463fd opj_j2k_decode_tiles(): apply whole single tile image decoding optimization to reading at reduced resolution as well 2017-09-01 16:30:45 +02:00
Even Rouault 98b9310361 Various changes to allow tile buffers of more than 4giga pixels 
Untested though, since that means a tile buffer of at least 16 GB. So
there might be places where uint32 overflow on multiplication still occur...
 2017-09-01 16:30:44 +02:00
Even Rouault 008a12d4fc TCD: allow tile buffer to be greater than 4GB on 64 bit hosts (but number of pixels must remain under 4 billion) 2017-09-01 16:30:41 +02:00
