2020-06-06Remove some assert()s which, strangely, seem to slow things down even in ↵optCarl Hetherington
release mode.
2019-12-03Add some more errno to debug 'failed to start J2K encoding'Carl Hetherington
2019-12-03Revert "Packet header writing: set empty packet header bit to 0 when ↵Carl Hetherington
appropriate (small optimization)" This reverts commit 2609fb8077125b5b31f1bcc2f98c12ff1e6572d7. I am testing this reversion to see if it fixes problems with DCP playback on various systems (DCP-o-matic bug #1136).

And save a useless loop, which should be a tiny faster.

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)

2017-08-28Make opj_set_decode_area() and opj_decode() take into account ↵Even Rouault
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.

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.
