2007-03-20Added feature for generation of tile parts. Modifications in image_to_j2k.c, ↵Parvatha Elangovan
openjpeg.c, j2k.c, pi.c Added function j2k_write_tlm(),to generate TLM marker for a Digital cinema compliant codestream. Modifications in j2k.c.
2007-03-07Added option for Digital cinema profile compliant codestream. This can be ↵Parvatha Elangovan
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 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 Added feature for constant quality within bitrate defined in Digital cinema standards. Modification in tcd.c Modified the method of generation of buffer length. Modification in cio.c
2007-02-28Enabled compression of TIF image format to j2k by tifftoimage() and ↵Parvatha Elangovan
decompression of codestream to TIF image format using imagetotif(). Modifications in image_to_j2k.c, j2k_to_image.c, convert.c, convert.h
2007-02-27Made get_file_format function more robust. Modifications in image_to_j2k.c, ↵Parvatha Elangovan
j2k_to_image.c, getopt.c, getopt.h
2007-02-26Option to read images from a Folder whose path is specified in the Input ↵Parvatha Elangovan
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 Enabling use of multi character input parameters in the codec. Modifications in image_to_j2k.c, j2k_to_image.c, getopt.c, getopt.h
2007-02-13David Fries suggestions. In image_to_j2k and j2k_to_image, strncpy() ↵Francois-Olivier Devaux
functions: instead of specifying the path size macro, let the compiler read the length out of the array entry.
2007-01-31Extra tokens at the end of #endif directive corrected in openjpeg.c, j2k.c ↵Francois-Olivier Devaux
and image_to_j2k.c -> no more warnings in linux compilation
2007-01-30Use of OPJ_PATH_LEN (defined as 4096) to be the maximum allowed size for ↵Francois-Olivier Devaux
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

2004-05-07* Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the ↵Antonin Descampe
command line when encoding an image generates layers with the corresponding psnr. You have to specify values in the increase order. This option is incompatible with "-r" or "-f" options. * Old -q option is now available with -f * The INDEX-file structure has been modified and is now like this : ------------------------------ image_width image_height progression order tile_width tile_height nb_tiles_width nb_tiles_height nb_components nb_layers nb_decompositions foreach resolution_level {[precinct_width,precinct_height]} main_header_end codestream_size foreach tile { tileno start_pos end_header end_pos squarred_error_total nb_pixels mean_squarred_error } foreach tile { foreach packet { packetno tileno layerno resno compno precinctno start_pos end_pos SE_reduction } } SE max SE total -----------------------------
