Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(), as apparently memalign() is what is working better for everyone. Patch by Callum.

Minor style modifications to comply with c99 compiler flag; removed Microsoft-specific "union-in-struct" syntax; Re-enabled cstr_info struct creation when -W switch is specified. Changed a number of things in opjviewer (e.g., decoding thread does not execute GUI calls anymore), to have it running under linux --> it is better than before, but still crashes

In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order to avoid segfaults when freeing the memory allocated for the coding of bad images. Thanks to Christopher Layne for this improvement.

Avoided ABI breakage
2007-11-14 11:34:48 +00:00
010ae27471
Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.

Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.

Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c

Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy.

Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard. This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)

Warning: The output image size is now reduced when discarding resolutions !
