Francois-Olivier Devaux 26606c71c8 First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis (www.telemis.com). Thank you Patrick for this new module ! 2007-12-10 13:16:01 +00:00
Francois-Olivier Devaux 9e5d165e79 Fixed the maximum number of resolutions a user can discard while decoding.
Added an error state in J2K_STATE (j2k.c)

Francois-Olivier Devaux 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. 2007-11-14 10:52:02 +00:00
Francois-Olivier Devaux 24e189e4d8 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. 2007-11-14 08:45:00 +00:00
Francois-Olivier Devaux dbeebe72b9 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. 2007-11-13 17:35:12 +00:00
Francois-Olivier Devaux 9e114bcaa4 Patch from Callum Lewick. Memset patch. See ChangeLog for more details. Thanks Callum ! 2007-10-18 12:26:11 +00:00
Francois-Olivier Devaux 1f11a4fe90 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 !
