Andrew Murray 157a3d8408 Changed cmake version test to allow for cmake 2.8.11.x 2017-11-14 21:45:09 +11:00
Even Rouault e8b6b54d1f opj_decompress -h: document -threads ALL_CPUS 2017-10-06 19:25:07 +02:00
Antonin Descampe d45ccb048b Merge pull request #1022 from rouault/partial_component_decoding 
Add capability to decode only a subset of all components of an image.
 2017-09-26 18:30:20 -03:00
Even Rouault 16b701659d opj_decompress: add a warning when -d and -t are used together (#693) 2017-09-20 01:06:02 +02:00
Even Rouault e17bbde906 opj_set_decoded_components(): add a provision for a apply_color_transforms parameter in case we support it in the future 2017-09-19 17:48:07 +02:00
Even Rouault 7e2b6bebff Add capability to decode only a subset of all components of an image. 
This adds a opj_set_decoded_components(opj_codec_t *p_codec,
OPJ_UINT32 numcomps, const OPJ_UINT32* comps_indices) function,
and equivalent "opj_decompress -c compno[,compno]*" option.

When specified, neither the MCT transform nor JP2 channel transformations
will be applied.

Tests added for various combinations of whole image vs tiled-based decoding,
full or reduced resolution, use of decode area or not.

Even Rouault 968e36bbd9 Merge pull request #1010 from rouault/subtile_decoding_stage3 
Subtile decoding: memory use reduction and perf improvements
 2017-09-05 22:18:58 +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 3257261776 opj_compress help: indicate 0 value, instead of 1, for -r parameter to get lossless encoding (#1009) 2017-09-01 17:33:23 +02:00
Even Rouault aa7198146b opj_compress: reorder checks related to code block dimensions, to avoid potential int overflow 2017-09-01 10:26:53 +02:00
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.

Even Rouault af76000771 tiftoimage(): fix read heap buffer overflow (#988) 
The number of components is given only by TIFFTAG_SAMPLESPERPIXEL / tiSpp.
Querying TIFFTAG_EXTRASAMPLES only give information about which channel is
the alpha channel, but we mostly ignore it for now, so remove that part of the
code.
