openjpeg/tests/nonregression, branch v2.3.0 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=v2.3.0 2017-09-19T15:06:19Z Add capability to decode only a subset of all components of an image. 2017-09-19T15:06:19Z Even Rouault even.rouault@spatialys.com 2017-09-19T14:52:07Z urn:sha1:7e2b6bebff12eab8bdc17fc9af017e8c11652f4f 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.

For clarity, tThis new bit has also been renamed to allow_different_bit_depth_sign But looking closer at the code, it seems we were already tolerant to inconsistencies. For example we parsed a JP2 BPCC box even if BPC != 255 (just a warning is emitted) So failing hard in opj_j2k_read_siz() wouldn't be very inconsistent, and that alone cannot protect against other issues, so just emit a warning if BPC != 255 and the SIZ marker contains different bit depth/sign per component. Note: we could also check that the content of JP2 BPCC box is consistant with the one of the SIZ marker.

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.
