39 CMakeLists.txt: Don't require a C++ compiler
41 commit 4d147d9630653e4c93a70a2a8026c323ed1042d2

45 CMakeLists.txt: Don't require a C++ compiler
47 By default, CMake assumes that the project is using both C and C++. By
48 explicitly passing 'C' as argument of the project() macro, we tell CMake
49 that only C is used, which prevents CMake from erroring out if a C++
50 compiler doesn't exist.

467 openjp2: Error out if failing to create Tier 1 handle.
469 Previously when the handle failed to be created (e.g. when
470 opj_calloc returned NULL due to low memory), the code still
471 assumed that the t1 handle pointer was valid and dereferenced
472 NULL, causing a crash. After this commit OpenJPEG will instead
473 error out under this condition.
475 This fixes issue #1255.

584 Irreversible compression/decompression DWT: use 1/K constant as per standard
586 The previous constant opj_c13318 was mysteriously equal to 2/K , and in
587 the DWT, we had to divide K and opj_c13318 by 2... The issue was that the
588 band->stepsize computation in tcd.c didn't take into account the log2gain of
591 The effect of this change is expected to be mostly equivalent to the previous
592 situation, except some difference in rounding. But it leads to a dramatic
593 reduction of the mean square error and peak error in the irreversible encoding

654 Add multithreaded support in the DWT encoder.
656 Update the bench_dwt utility to have a -decode/-encode switch
658 Measured performance gains for DWT encoder on a
659 Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz (4 cores, hyper threaded)
662 $ ./bin/bench_dwt -encode -num_threads 1
663 time for dwt_encode: total = 8.348 s, wallclock = 8.352 s
665 $ ./bin/bench_dwt -encode -num_threads 2
666 time for dwt_encode: total = 9.776 s, wallclock = 4.904 s
668 $ ./bin/bench_dwt -encode -num_threads 4
669 time for dwt_encode: total = 13.188 s, wallclock = 3.310 s
671 $ ./bin/bench_dwt -encode -num_threads 8
672 time for dwt_encode: total = 30.024 s, wallclock = 4.064 s
674 Scaling is probably limited by memory access patterns causing
675 memory access to be the bottleneck.
676 The slightly worse results with threads==8 than with thread==4
677 is due to hyperthreading being not appropriate here.
