2017-08-09Partial revert BPC related check of #975 (#979)Even Rouault
PR #975 introduced a check that rejects images that have different bit depth/sign per compoment in SIZ marker if the JP2 IHDR box has BPC != 255 This didn't work properly if decoding a .j2k file since the new bit added in opj_cp_t wasn't initialized to the right value. 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.

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.
