1 What's New for OpenJPEG
9 * [Parvatha] Enable accepting file names with `-� symbol .Modification getopt.c
10 * [Parvatha] Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c
11 ! [Parvatha] renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c
12 * [Parvatha] Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c
13 ! [Parvatha] j2k_setup_encoder to set bit rate limitation for digital cinema compliance with quality option. Modification in j2k.c

20 * [FOD] Fixed an historical bug in t1.c that leaded to the inclusion of useless 0xFF in the codestream. Thanks to Sylvain, Pascal and Parvatha !
23 + [GB] Improved parsing in OPJViewer, as well some minor aesthetic modifications; support for image rendering with bit depths lower than 8 bits; can display an arbitrary frame of an MJ2 file (only in B/W, though); can reload a file; better resizing capabilities
24 * [GB] Following to Herv�'s suggestions, all the exit() calls, added by JPWL strict checking in t2.c and j2k.c, have been substituted with (object free'ing + opj_evt_message(EVT_ERROR) + return)
25 + [GB] Added linking to TIFF library in the JPWL VC6 workspaces
28 * [antonin] Fixed Makefile.osx and changed Readme.osx accordingly
31 * [Parvatha] Fixed j2k_prog_order_list[]. Modifications in j2k.c.
32 * [Parvatha] Fixed t1_decode_cblks. Modifications in t1.c.
35 + [Parvatha] Added feature for generation of tile parts. Modifications in image_to_j2k.c, openjpeg.c, j2k.c, pi.c
36 + [Parvatha] Added function j2k_write_tlm(),to generate TLM marker for a Digital cinema compliant codestream. Modifications in j2k.c.
39 * [FOD] Fixed linux makefile, with help from David Fries and Guido
42 + [Parvatha] Added option for Digital cinema profile compliant codestream. This can be chosen by "-cinema2K" or "-cinema4K" for a 2K and 4K compliance respectively. The feature for tileparts has not been implemented in this version. Modification in image_to_j2k.c
43 + [Parvatha] Added the Digital Cinema profiles (CINEMA2K and CINEMA4K) to the list of profiles recognized in the codestream SIZ marker segment. Modification in openjpeg.h,j2k.c
44 + [Parvatha] Added feature for constant quality within bitrate defined in Digital cinema standards. Modification in tcd.c

49 * [FOD] Modified codec projects (*.dsp) and makefile to include the tiff library (modified codec/image_to_j2k.dsp codec/j2k_to_image.dsp and codec/makefile)
50 + [GB] Zoom capability and decoder settings dialog in OPJViewer; modified JPWL library .dsp project in order to create a library with embedded JPWL functions
53 + [Parvatha] Enabled compression of TIF image format to j2k by tifftoimage() and decompression of codestream to TIF image format using imagetotif(). Modifications in image_to_j2k.c, j2k_to_image.c, convert.c, convert.h
54 * [antonin] fixed a bug in context numerotation that prevented the RESET switch to work correctly : mqc_reset_enc in mqc.c
55 * [Fod] Corrected codec Makefile by adding the compilation of "compat/getopt.c"
58 * [Parvatha] Made get_file_format function more robust. Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
61 + [Parvatha] Option to read images from a Folder whose path is specified in the Input parameters by "-ImgDir" along with output decod format specified by "-OutFor" . Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
62 + [Parvatha] Enabling use of multi character input parameters in the codec. Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
65 * [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
66 * [FOD] Changed version number from 1.1.0 to 1.1.1 in openjpeg.h
67 + [GB] Linux makefile for the JPWL module; newlines at end of JPWL files

73 + [FOD] Algorithmic optimizations in t1.c, thanks to Guido J. !
76 + [FOD] Added OPJ_LIMIT_DECODING enabling us to limit the decoding to main header (modified openjpeg.c, openjpeg.h, j2k.c and j2k.h)
79 ! [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.
80 ! [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.
83 ! [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
84 ! [FOD] Linux Makefile added for the codec
87 ! [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
88 ! [FOD] Correction of the syntax usage in MJ2_codec/mj2_to_frames.c
91 ! [FOD] Modification in the context numbers, to reflect what has been specified in standard, in libopenjpeg/t1.h
94 + [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
97 * [Giuseppe Baruffa] Better fix of the TPH EPBs bug in JPWL module
98 * [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
99 + [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
103 + [Francois-Olivier Devaux] New tag: version1.0 (includes codec and libopenjpeg directories)
104 Total update of JPWL module
105 - [FOD] removed directories jpwl/decoder, jpwl/encoder, jpwl/decoder_02, jpwl/encoder_02
