1 What's New for OpenJPEG
9 - [FOD] JP3D library Binaries removed from SVN.
10 ! [FOD] MJ2 codec updated from LibOpenJPEG version 0.97 to LibOpenJPEG version 1. Hence, the MJ2 codec will now take advantage of all the improvements and optimizations done on the LibOpenJPEG library.
11 ! [FOD] Possibility to choose to apply MCT (multiple component transform) enabled, and new decoding_limit: DECODE_ALL_BUT_PACKETS (openjpeg.h)
14 + [gdcm] Add basic steps on how to use CMake for building examples (README.cmake)

38 + [Parvatha] Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
39 + [Parvatha] Structure T2_MODE. This tells if the t2_encode_packets() is called during Threshold calculation or in Final pass. Modification in j2k.h, tcd.c
42 * [GB] OPJViewer should now work under Linux, at least with not big j2k files. Tested under Suse 10.1 64 bit.

101 * [GB] Fixed a copy-and-paste type assignment error (bool instead of int) in the JPWL section of decoder parameters structure in openjpeg.h; minor type-casting in jpwl_lib.c. As a result, now OPJViewer should run correctly when built against the most current SVN trunk of LibOpenJPEG.lib
102 * [FOD] Changed version number from 1.1.0 to 1.1.1 in openjpeg.h
103 + [GB] Linux makefile for the JPWL module; newlines at end of JPWL files

115 ! [FOD] David Fries suggestions. In image_to_j2k and j2k_to_image, strncpy() functions: instead of specifying the path size macro, let the compiler read the length out of the array entry.
116 ! [FOD] David Fries suggestions. Makefile modified. -fPIC flag used for 64-bit compilation. Move operation (rather than copy) for the dist library creation, and -p flag added.
119 ! [FOD] Extra tokens at the end of #endif directive corrected in openjpeg.c, j2k.c and image_to_j2k.c -> no more warnings in linux compilation
120 ! [FOD] Linux Makefile added for the codec
123 ! [FOD] Use of OPJ_PATH_LEN (defined as 4096) to be the maximum allowed size for filenames instead of MAX_PATH which is not always defined. This caused some programs using OpenJPEG to crash. Modifications in openjpeg.h j2k_to_image.c and image_to_j2k.c
124 ! [FOD] Correction of the syntax usage in MJ2_codec/mj2_to_frames.c

130 + [Giuseppe Baruffa] Antonin verified that the MacOS build suffered from a missing definition of the "min" macro; I've added this definition (properly #ifndef'ed) into both jpwl.h and rs.h
133 * [Giuseppe Baruffa] Better fix of the TPH EPBs bug in JPWL module
134 * [GB] Fixed the UEP bug in JPWL module; now, during a UEP specification, RS protection or CRC check can be switched off for selected range of packets, and consequently reswitched on without confusing the decoder
135 + [GB] Added some lines in the help of JPWL_image_to_j2k, specifying that when using error protection on data packets, this must be paired with header protection, i.e. there cannot be packet protection without header protection

140 Total update of JPWL module
141 - [FOD] removed directories jpwl/decoder, jpwl/encoder, jpwl/decoder_02, jpwl/encoder_02
