Even Rouault 92114694a4 Slight improvement in management of code block chunks 
Instead of having the chunk array at the segment level, we can move it down to
the codeblock itself since segments are filled in sequential order.
Limit the number of memory allocation, and decrease slightly the memory usage.

On MAPA_005.jp2

Even Rouault ca34d13e76 Decoding: do not allocate memory for the codestream of each codeblock 
Currently we allocate at least 8192 bytes for each codeblock, and copy
the relevant parts of the codestream in that per-codeblock buffer as we
decode packets.
As the whole codestream for the tile is ingested in memory and alive
during the decoding, we can directly point to it instead of copying. But
to do that, we need an intermediate concept, a 'chunk' of code-stream segment,
given that segments may be made of data at different places in the code-stream
when quality layers are used.

With that change, the decoding of MAPA_005.jp2 goes down from the previous
improvement of 2.7 GB down to 1.9 GB.

Even Rouault f58aab9d6a Add opj_image_data_alloc() / opj_image_data_free() 
As bin/common/color.c used to directly call malloc()/free(), we need
to export functions dedicated to allocating/freeing image component data.

Even Rouault 61fb5dd7f8 Fix crash on Windows due to b7594c0fcb9dd3aa6356d72c4a525d76168da689 
b7594c0fcb9dd3aa6356d72c4a525d76168da689 may put opj_tcd_tilecomp_t->data
allocated by opj_alloc_tile_component_data() as the image->comps[].data. As
opj_alloc_tile_component_data() use opj_aligned_malloc() we must be sure to
ue opj_alined_malloc()/_free() in all places where we alloc/free
image->comps[].data.

Note: this might have some compatibility impact in case user code does itself
the allocation/free of image->comps[].data
 2017-08-07 18:32:49 +02:00
Even Rouault 793edc38e4 Decrease memory consumption for whole image single tile decoding. 
We can use the same buffer for the tile decoding and the final image, and
save the intermediate buffer to transfer between those.

Effect on the decoding of MAPA (9944 x 13498 x 3 components of size byte)

Peak memory from 4.5 GB to 2.7 GB

* Use single-pass lifting inverse wavelet transform.
* For vertical pass, use SSE2 when available so as to process 8 columns

  vertical pass involves a lot of cache trashing.

With the bench_dwt utility with default arguments (16383x16383 image),
time goes from 4.064 s to 1.212 s.

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 532243f1fd MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. 
This saves comparing the current pointer with the end of buffer pointer.

decoding. Encoding using the mqc structure already.

Besides that, the image is correctly decoded. So there is no reason to emit

Even Rouault 87c0d7dc1e [git/2.1 regression] Fix opj_write_tile() failure when numresolutions=1 
When trying the GDAL OpenJPEG driver against openjpeg current master HEAD,
I get failures when trying to create .jp2 files. The driver uses
opj_write_tile() and in some tests numresolutions = 1.

In openjp2/dwt.c:410, l_data_size = opj_dwt_max_resolution( tilec->resolutions,tilec->numresolutions) * (OPJ_UINT32)sizeof(OPJ_INT32);
is called and returns l_data_size = 0. Now in git opj_malloc() has a special case
for 0 to return a NULL pointer whereas previously it relied on system malloc(),
which in my case didn't return NULL.

So only test the pointer value if l_data_size != 0. This makes the GDAL
autotest suite to pass again.

Stefan Weil 9cad6bc1f6 Fix fatal crash on 64 bit Linux 
By default, OpenJPEG uses the function memalign to allocate aligned
memory on Linux systems. That function needs malloc.h which was
missing. This results in a compiler warning:

openjpeg/src/lib/openjp2/opj_malloc.c:63:3: warning:
 implicit declaration of function ‘memalign’
 [-Wimplicit-function-declaration]

On hosts where sizeof(int) < sizeof(void *) the return value of memalign
will be truncated which results in an invalid pointer.

That caused "make test" to produce lots of segmentation faults when
running on a 64 bit Linux host.
