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

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

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 !

8f3bd54c3d Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu 
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double

c83ae7397d Added layer option '-l' to the command line. This option allows user to 
specify a maximum number of quality layers to be decoded.
