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.

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
Even Rouault d1299d9670 Fix compiler warning in release mode 2017-09-01 16:30:39 +02:00
Even Rouault d5153ba404 Remove limitation that prevents from opening images bigger than 4 billion pixels
However the intermediate buffer for decoding must still be smaller than 4
billion pixels, so this is useful for decoding at a lower resolution level,
or subtile decoding.

Even Rouault c37e360a51 opj_tcd_init_tile(): fix typo on overflow detection condition (introduced in previous commit) 2017-09-01 16:30:35 +02:00
Even Rouault eee5104a88 opj_dwt_decode_partial_tile(): avoid undefined behaviour in lifting operation by properly initializing working buffer 2017-09-01 16:30:32 +02:00
Even Rouault f9e9942330 Sub-tile decoding: only allocate tile component buffer of the needed dimension
Instead of being the full tile size.

* Use a sparse array mechanism to store code-blocks and intermediate stages of
  IDWT.
* IDWT, DC level shift and MCT stages are done just on that smaller array.
* Improve copy of tile component array to final image, by saving an intermediate
  buffer.
* For full-tile decoding at reduced resolution, only allocate the tile buffer to
  the reduced size, instead of the full-resolution size.

Even Rouault 8f92fc9791 Make opj_set_decode_area() and opj_decode() take into account opj_set_decoded_resolution_factor() (#1006, affect API use)
* Better document usage of opj_set_decode_area(), ie expecting coordinates
  in full resolution/reference grid even if requesting at a lower resolution
  factor
* Make sure that image->comps[].factor is set by opj_set_decode_area() and
  opj_decode() from the value specified in opj_set_decoded_resolution_factor()
* opj_decompress: add 2 environmenet variables to test alternate ways of
  using the API, namely USE_OPJ_SET_DECODED_RESOLUTION_FACTOR=YES to use
  opj_set_decoded_resolution_factor() instead of parameters.cp_reduce, and
  SKIP_OPJ_SET_DECODE_AREA=YES to not call opj_set_decode_area() if -d is
  not specified.
