+
+ Irreversible compression/decompression DWT: use 1/K constant as per standard
+
+ The previous constant opj_c13318 was mysteriously equal to 2/K , and in
+ the DWT, we had to divide K and opj_c13318 by 2... The issue was that the
+ band->stepsize computation in tcd.c didn't take into account the log2gain of
+ the band.
+
+ The effect of this change is expected to be mostly equivalent to the previous
+ situation, except some difference in rounding. But it leads to a dramatic
+ reduction of the mean square error and peak error in the irreversible encoding
+ of issue141.tif !

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

- openjp3d: Int overflow fixed (#1159)
-
- When compressing a lot of slices (starting from 44 FullHD slices with 3 8bit components in our experiments) the rate values are high enough to cause an int overflow that leads to negative lengths and wrong results. The cast happens too late.

- jp2: convert: fix null pointer dereference
-
- Tile components in a JP2 image might have null data pointer by defining a
- zero component size (for example using large horizontal or vertical
- sampling periods). This null data pointer leads to null image component
- data pointer, causing crash when dereferenced without != null check in
- imagetopnm.
-
- Add != null check.

- This commit addresses #1152 (CVE-2018-18088).

- * Fix some potential overflow issues
-
- Put sizeof to the beginning of the multiplication to enforce that
- size_t instead of smaller integer types is used for the calculation.
-
- This fixes warnings from LGTM:
-
- Multiplication result may overflow 'unsigned int'
- before it is converted to 'unsigned long'.
-
- It also allows removing some type casts.

- opj_mj2_extract: Check provided output prefix for length
-
- This uses snprintf() with correct buffer length instead of sprintf(), which
- prevents a buffer overflow when providing a long output prefix. Furthermore
- the program exits with an error when the provided output prefix is too long.
-
- Fixes #1088.
