Thanks a lot Mathieu 2005-11-01T10:15:34Z Antonin Descampe antonin@gmail.com 2005-11-01T10:15:34Z urn:sha1:8f3bd54c3dd0403aae45abccdcc850eab5faeb6a - '//' 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 1) quantization stepsizes stored as float instead of shifted integers -> fixes a pb of precision when using very small stepsizes. 2) bug fixed when decoding until bitplane 0 -> r-value (1/2) added to the coefficient. 2005-10-27T07:49:29Z Antonin Descampe antonin@gmail.com 2005-10-27T07:49:29Z urn:sha1:7ee36c3a4c37d9c8cee30ac19fd5532a3863285b At lines 577, 692 and 699, zeroing of effective region of code-block rather than the 1024*1024 allocated integers of code-block. This optimization has been proposed by Dmitry Kolyadin.
