Even Rouault 2609fb8077 Packet header writing: set empty packet header bit to 0 when appropriate (small optimization) 2017-06-12 18:38:11 +02:00
Even Rouault 73d1510d47 Encoder: fix packet writing of empty sub-bands (#891, #892) 
There are situations where, given a tile size, at a resolution level,
there are sub-bands with x0==x1 or y0==y1, that consequently don't have any
valid codeblocks, but the other sub-bands may be non-empty.
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.

Even Rouault 81c5311758 T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes. (#674) 
There were a number of defects regarding when and how the termination of
passes had to done and the computation of their rate.

Even Rouault 9a9b06911e opj_t1_dec_sigpass_raw/opj_t1_dec_refpass_raw: harmonize style with mqc methods 2017-06-02 19:22:15 +02:00
Even Rouault 532243f1fd MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. 
This saves comparing the current pointer with the end of buffer pointer.
This results at least in tiny speed improvement for raw decoding, and
smaller code size for MQC as well.

This kills the remains of the raw.h/.c files that were only used for
decoding. Encoding using the mqc structure already.

Even Rouault cd12414c6b T1: use more compact flags to optimize cache usage in encoder passes. (#172) 
Ported from Carl Hetherington work (actually through Matthieu Darbois's port
on top of OpenJPEG 2.1.0)

Can reduce total encoding time by 10-15%

WARNING: VSC mode is not implemented, and so is a temporary regression
that must be fixed.
