2007-05-23Bug fixed by Sylvain Munaut. Change in the reading of the POC marker. Since ↵Francois-Olivier Devaux
COD/COC can be anywhere in the header, the decoder cannot always know while decoding the POC marker the value of numlayers and numresolution.
2007-05-22Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data ↵Francois-Olivier Devaux
arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts"
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting ↵Francois-Olivier Devaux
cleanups, so that the long function definitions and calls fit on screen. Use of prefix increment which is theoretically faster, in practice any sane compiler can optimize a postfix increment but its best not to count on such things. Consolidation of some redundant calculations in the inner loops, which becomes very useful in the future autovectorize patch."
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "This changes the flag ↵Francois-Olivier Devaux
code in t1 to use a flag_t type, which can then be changed to reduce RAM usage. It is now typedef to a short."
2007-05-21Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 ↵Francois-Olivier Devaux
LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely."
