December 10, 2007
+ [FOD] First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis (www.telemis.com).
Thank you Patrick for this new module !
November 29, 2007
! [GB] Added index.h and index.c in VC6 projects; wrapped index.h in the C++ preprocessor; modified OPJViewer project and some files.
November 14, 2007
+ [FOD] Created the file index.c in the codec directory. This file handles the creation of index files,
at encoding and decoding.
* [FOD] Fixed bugs during the creation of the index (PCRL progression order)
* [FOD] Fixed the maximum number of resolutions a user can discard while decoding.
Added an error state in J2K_STATE (j2k.c)
November 14, 2007
! [FOD] - First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
- Second Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as
late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.
- Third Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it
contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates
the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size
them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate
encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.
* [FOD] Avoided ABI breakage
November 13, 2007
! [FOD] Patch by Dzonatas and Callum Lerwick.
Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point,
eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement,
and an increase in accuracy.
November 8, 2007
! [FOD] In t1.c, small change to avoid calling twice t1_getwmsedec()
Patches from Callum Lewick:
- Basic gcc optimization flags in cmake and makefile match.
- Fixed some spelling errors in dwt.c.
November 5, 2007
*+ [GB] Fixed a bug which prevented JPWL from working on multi-tiled images; added some more fields in the interface info structures
(keep a list of markers, save start packet number for each tile)
October 23, 2007
* [GB] Improved success for the linux build; OPJViewer shows all the COM contents
October 18, 2007
* [FOD] Changed the ROI parameter in the image_to_j2k codec to make it correspond to the documentation (i.e. -ROI c=0,U=25)
* [FOD] Patch from Callum Lewick. Memset patch.
The main idea of the patch is that currently opj_malloc clears all allocations, which unnecessarily
dirties up the cache and eats bandwidth. This patch makes it no longer do so, and I've painstakingly determined which allocations actually need
to be cleared and changed them to use opj_calloc() instead. I previously tried to just get rid of the opj_*alloc wrappers but that
idea was nixed, so this time I'm trying it with macros. I also put in a gcc pragma that helps enforce their use. Which got messy. :) It caught a
few places they weren't used but it also revealed that the mj2 tools are not very cleanly separated from the library. It includes all the
internal headers, but it wasn't using the malloc wrappers. I figured the binaries should be "external" and have minimal knowledge of the
internals of the library. I patched them to not include opj_includes.h, and include only the internal headers they actually need. However,
they're using the opj_clock() function, which is in with the malloc wrappers. So I decided to move the malloc wrappers to their own header.
But mj2.c seems to want to be "internal", so I patched it to use the wrappers. Note that this patch changes the semantics of opj_malloc, it no longer
clears the memory it allocates. If you need it to be cleared, you must use opj_calloc instead, or memset it yourself. It is also somewhat
invasive, please test it extensively. I've been pounding on it all summer with my test suite, Second Life, and valgrind, and it checks out clean.
October 12, 2007
* [FOD] Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard.
This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
Warning: The output image size is now reduced when discarding resolutions !
October 10, 2007
* [FOD] Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff.
It makes it work right with mingw, as _mm_malloc() isn't a macro, attempts to pave the way to using cmake
to check for this stuff and combines a patch from Dana Fagerstrom at Sun that makes it use memalign() on Solaris
convert.c: Changed some error comments for TIFF images
September 27, 2007
* [FOD] Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64.
September 25, 2007
* [Mathieu Malaterre] BUG: Fix previous patch from Callum Lerwick. I have no
clue what CMAKE_INSTALL_LIBDIR refers too. Bump up cmake 2.2 restriction to
cmake 2.4 because of previous patch (not backward compatible). Properly set the SOVERSION in a cross plateform way (yes WIN32 is a platform)
September 19, 2007
* [Parvatha] Fixed issues with generation of SOP marker.
September 18, 2007
* [Parvatha] Fixed issues with Reading and Writing TIF images in convert.c to avoid segmentation fault.
* [Parvatha] Fixed issues relating to using user specified rates for CINEMA option for multiple images.
September 17, 2007
* [FOD] Fixed issues with cstr_info when codestream has components with different number of resolutions.
! [FOD] OpenJPEG library interface modified to retain compatibility with version 1.2
September 12, 2007
* [FOD] Patch from Callum Lerwick.
Fixed the library linking so it links with the soversion properly set.
Fixes up the install targets so that it interacts properly with RPM.
Install target for MJ2. Sets some necessary and useful CFLAGS if gcc is in use.
* [FOD] Updated the MJ2 codec to be compatible with the recent changes in the OpenJPEG library
September 11, 2007
* [GB] JPWL encoding is finalized correctly into the JP2 file format; added an additional structure in opj_codestream_info, to keep a record of the written markers
September 8, 2007
* [GB] Adapted the JPWL and OPJViewer code to new interface; fixed a samll bug in JPWL which created large EPBs even when null protection was specified
September 7, 2007
+ [FOD] Indexes can now be generated when decoding J2K codestreams.
* [Mathieu Malaterre] Upon failure, properly return error code (!=0).
* [Mathieu Malaterre] CMake: Add cmake code to do testing if user has properly setup a testimages directory
September 6, 2007
+ [Mathieu Malaterre] CMake: start compiling mj2, jpwl and jp3d
+ [Mathieu Malaterre] CMake: output all executable/libs into one single directory
+ [Mathieu Malaterre] CMake: start compiling index_create
+ [Mathieu Malaterre] OpenJPEG.rc update copyright year
+ [Mathieu Malaterre] CMake: add Java j2kviewer but do not compile it using cmake since cmake has too poor support for Java. Should create a custom command running ant instead.
+ [Mathieu Malaterre] CMake: Add doxygen output
+ [GB] One more field in the codestream_info struct for recording the number of packets per tile part; JPWL now distributes the EPBs in all the tile part headers
+ [Mathieu Malaterre] CMake: Add very simple tests (simply run command line with no option)
* [Mathieu Malaterre] Fix unitialized read in img_fol (we may need a smarter initialize than memset)
September 4, 2007
+ [GB] Added some fields in the codestream_info structure: they are used to record the position of single tile parts.
Changed also the write_index function in the codec, to reflect the presence of this new information.
September 3, 2007
+ [GB] Added the knowledge of JPSEC SEC and INSEC markers (you have to compile the JPWL project). Management of these markers is limited to skipping them without crashing:
no real security function at this stage. Deprecated USE_JPSEC will be removed next
August 31, 2007
* [GB] Fixed save capabilities in OPJViewer due to recent code upgrade
August 30, 2007
* [FOD] Changed the OpenJPEG library interface to enable users to access information regarding the codestream (also called codestream index).
This index is usefull for all applications requiring to have a scalable acces to the codestream (like JPIP applications, ...)
Currently, this information is only available when encoding an image.
+ [FOD] Added the information regarding the end of packet position in the index
August 28, 2007
* [FOD] Fixed wrong destructors called in openjpeg.c
* [FOD] Fixed bug in j2k_decode_jpt_stream
August 24, 2007

* [Callum Lerwick] Minor cleanup patch, that gets rid of a bunch of "old style declaration" warnings from Intel's compiler
* [Callum Lerwick] Aligned malloc using Intel's _mm_malloc(). Cleanup on the t1 memory allocation, getting rid of some leftover debug code
* [Callum Lerwick] Memory leaks fixed
* [Callum Lerwick] Reworks of t1_updateflags to get rid of the shift operation
* [Callum Lerwick] mqc_setcurctx moved to the header to allow it to be inlined into the t1.
* [Callum Lerwick] Consolidated some calls to mqc_setcurctx.
* [Callum Lerwick] Cleaned up t1_generate_luts to output the proper types.
* [Callum Lerwick] Replaced the large ctxno_mag lookup table with a small bit of inline-able branchless code
* [Callum Lerwick] Moved the orient flipping into the ctxno_zc table.
August 20, 2007
+ [FOD] Added support for the TGA file format in the codec

+ [GB] Added a basic saving capability to OPJViewer
July 18, 2007
! [FOD] Updated libtiff library version to 3.8.2 (for WIN32)
* [FOD] Updated BMP and PxM truncation when decoding J2K files with more than 8 bits
July 17, 2007
* [FOD] Fixed raw option for images with more than three components
July 17, 2007
+ [FOD] Added support for RAW images. This module has been developped by the University of Perugia team. Thanks to them ! [image_to_j2k.c j2k_to_image.c convert.c convert.h]
July 13, 2007
! [FOD] Modified the memory allocation for codestreams containing multiple tiles. The memory is now allocated for each tile indenpendently,
leading to an important decrease of the virtual memory needed. [j2k.c tcd.h tcd.c]
! [FOD] Modified old comments about the ability to decode mega-images and comments about the disk size necessary to do this. [image_to_j2k.c and frames_to_mj2.c]
* [FOD] Added 2000 bytes for the memory allocation in cio.c for the minimum size of headers (useful in case of very small images) [cio.c]
July 12, 2007
* [GB] fixed a bug in JPWL module, which prevented to exploit the full error correction capability of RS codes (e.g. it gave up at 5 errors,
even if 6 were correctable); defined a JPWL_MAXIMUM_EPB_ROOM for better customization of the maximum dimension of EPBs (the dimension
is pre-calculated on an hypothesis, if it goes beyond 65535 there will be problems, thus we give a little less than the max, let's say 65450)
July 8, 2007
* [ANTONIN] fixed the size of the memory allocation in cio.c (confusion between bits and bytes)
June 21, 2007
* [FOD] Output image color space set when decoding a JP2 file in jp2.c
+ [GB] Previous, home, and next frame buttons for exploring MJ2 files in OPJViewer
June 18, 2007

June 16, 2007
+ [GB] Possibility to disable parsing in OPJViewer; also, saves common settings to the registry
June 15, 2007
* [FOD] Fixed the generation of index files
----------------------
MAY 4, 2007
VERSION 1.2.0 RELEASED
----------------------
May 4, 2007
* [FOD] Bugs corrected in decoding of command line (getopt.c), in the handling of 16 bit files (t1.c and tcd.c) and the calculation of elapsed time for multiple tiles parts (tcd.c and tdc.h).
June 2, 2007
+ [GB] OPJViewer opens now BMP, PNG, GIF, PNM, TIFF (with wxWidgets internals); added an encoder settings tab, for future integration with "save file as..." in JPEG 2000 format
May 31, 2007
* [FOD] Fixed the handling of 16bit TIFF files for cinema compression. Modified "convert.c"
* [FOD] Fixed the parameters used for cinema compression (9-7 transform used instead of 5-3). Modified "image_to_j2k.c"
May 24, 2007
* [FOD] Bug fixed by Sylvain Munaut. Change in the reading of the POC marker. Since COD/COC can be anywhere in the header, the decoder cannot always know while decoding the POC marker
the value of numlayers and numresolution.
May 23, 2007
! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts"
May 22, 2007
! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "Some formatting 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."
! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "This changes the flag 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."
! [FOD] Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely."
May 11, 2007
- [FOD] JP3D library Binaries removed from SVN.
! [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.
! [FOD] Possibility to choose to apply MCT (multiple component transform) enabled, and new decoding_limit: DECODE_ALL_BUT_PACKETS (openjpeg.h)
April 26, 2007
+ [gdcm] Add basic steps on how to use CMake for building examples (README.cmake)
April 25, 2007
+ [FOD] Modification of the openjpeg.h file to avoid and ABI break with v1.1, removed the dangerous #IFDEF JPWL and added tcp_mct in cparameters.
April 23, 2007
+ [GB] Enable/disable image decoding in OPJViewer
April 12,2007
* [Parvatha] Fixed Error in tiftoimage(). Modification in convert.c.

! [FOD] dwt.c optimized. Thanks a lot to Dzonatas <dzonatas at dzonux.net> !
! [FOD] t1.c optimized. Thanks a lot to Callum Lerwick <seg at haxxed.com> !
April 4,2007
+ [Parvatha] Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification in image_to_j2k.c.
+ [Parvatha] Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c.
* [Parvatha] Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c.
+ [Parvatha] Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
+ [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
March 30, 2007
* [GB] OPJViewer should now work under Linux, at least with not big j2k files. Tested under Suse 10.1 64 bit.
March 29, 2007
* [Parvatha] Enable accepting file names with `-´ symbol .Modification getopt.c
* [Parvatha] Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c

VERSION 1.1.1 RELEASED
----------------------
February 23, 2007
* [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
+ [GB] Linux makefile for the JPWL module; newlines at end of JPWL files
February 22, 2007
+ [FOD] Added the OPJViewer Module (/OPJViewer), developed by Giuseppe Baruffa of the university of Perugia
February 21, 2007
+ [FOD] Algorithmic optimizations in t1.c, thanks to Guido J. !
February 19, 2007
+ [FOD] Added OPJ_LIMIT_DECODING enabling us to limit the decoding to main header (modified openjpeg.c, openjpeg.h, j2k.c and j2k.h)
February 13, 2007
! [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.
! [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.
January 31, 2007
! [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
! [FOD] Linux Makefile added for the codec
January 30, 2007
! [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
! [FOD] Correction of the syntax usage in MJ2_codec/mj2_to_frames.c
January 23, 2007
! [FOD] Modification in the context numbers, to reflect what has been specified in standard, in libopenjpeg/t1.h
December 07, 2006
+ [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
December 05, 2006
* [Giuseppe Baruffa] Better fix of the TPH EPBs bug in JPWL module
* [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
+ [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
December 04, 2006
+ [Francois-Olivier Devaux] New tag: version1.0 (includes codec and libopenjpeg directories)
Total update of JPWL module
- [FOD] removed directories jpwl/decoder, jpwl/encoder, jpwl/decoder_02, jpwl/encoder_02
+ [FOD] added in JPWL directory crc.h, jpwl.h, rs.h, crc.c, jpwl.c, jpwl_lib.c, rs.c, JPWL_image_to_j2k.dsp, JPWL_j2k_to_image.dsp, LibOpenJPEG_JPWL.dsp, JPWL_image_to_j2k.dsw, JPWL_j2k_to_image.dsw
! [FOD] Modifications of libopenjpeg to integrate JPWL module (in libopenjpeg directory): j2k.c, j2k.h, openjpeg.c, openjpeg.h, opj_includes.g, t2.c
! [FOD] Modification of codec to integrate JPWL module (in codec directory): image_to_j2k.c, j2k_to_image.c
* [FOD] Corrected incorrect fprintf() formatting in codec/convert.c

Preliminary notes
-----------------
The Version 2 of openjpeg has been currently added as a branch on the repository.
All the trunk has been copied and files that needed to change have been patched. In comparison with the trunk, the 'jp3d' directory has been removed because it's based on a modified version of libopenjpeg version 1 and there is no plan to make it reach the version 2 status. Idem with the 'indexer_JPIP', which is obsolete and should be rewritten from scratch.
At the time of the branch creation, the following files and directories have been updated (or added) for version 2 :
* libopenjpeg/
* codec/
* test_Free_image_V2_tile_handling/ : a test program that uses libopenjpeg v2 and libfreeimage (see libs) to implement a basic codec.
* test_V2_tile_handling/ : a test program that generates a random image and (de)compresses it with libopenjpeg v2.
* CMakeLists.txt
* Free_CMakeImport.cmake
* opj_configure.h.in
Other files and directories from the trunk (project files, jpwl/, OPJViewer/, ...) have also been copied in the branch and should be modified progressively to comply with v2. Check the Changelog for updates on this topic.
Enjoy v2 and feel free to contribute !
Instructions to compile v2

*
* MSVC 1.0 scans automatic dependencies incorrectly when your project
* contains this very header. The problem is that MSVC cannot handle
* include directives inside #if..#endif block those are never entered.
* Since this header ought to compile in many different operating systems,
* there had to be several conditional blocks that are compiled only in
* operating systems for what they were designed for. MSVC 1.0 cannot
* handle inclusion of sys/dir.h in a part that is compiled only in Apollo
* operating system. To fix the problem you need to insert DIR.H into
* SYSINCL.DAT located in MSVC\BIN directory and restart visual C++.
* Consult manuals for more informaton about the problem.
*
* Since many UNIX systems have dirent.h we assume to have one also.
* However, if your UNIX system does not have dirent.h you can download one
* for example at: http://ftp.uni-mannheim.de/ftp/GNU/dirent/dirent.tar.gz.
* You can also see if you have one of dirent.h, direct.h, dir.h, ndir.h,
* sys/dir.h and sys/ndir.h somewhere. Try defining HAVE_DIRENT_H,
* HAVE_DIRECT_H, HAVE_DIR_H, HAVE_NDIR_H, HAVE_SYS_DIR_H and
* HAVE_SYS_NDIR_H according to the files found.

* one are you dealing with. Many dirent implementations already contain
* equivalent information in dirent structure but you cannot depend on
* this.
*
* The dirent structure contains several system dependent fields that
* generally have no interest to you. The only interesting one is char
* d_name[] that is also portable across different systems. The d_name
* field contains the name of the directory entry without leading path.
* While d_name is portable across different systems the actual storage
* capacity of d_name varies from system to system and there is no portable
* way to find out it at compile time as different systems define the
* capacity of d_name with different macros and some systems do not define
* capacity at all (besides actual declaration of the field). If you really
* need to find out storage capacity of d_name then you might want to try
* NAME_MAX macro. The NAME_MAX is defined in POSIX standard althought
* there are many MS-DOS and MS-Windows implementations those do not define
* it. There are also systems that declare d_name as "char d_name[1]" and
* then allocate suitable amount of memory at run-time. Thanks to Alain
* Decamps (Alain.Decamps@advalvas.be) for pointing it out to me.
*
* This all leads to the fact that it is difficult to allocate space
* for the directory names when the very same program is being compiled on

Version ****JPWLcorrect****
This version realizes a JPWL decoder based on OpenJPEG library.
Realized decoder accepts an input JPWL codestream, corrects errors sgnalling eventual
residual errors and finally outputs the corrected JPWL codestream. This codestream shall
be used by a JPEG2000 Part-1 decoder to decode the image.
How to use decoder from prompt line:
"jpwl_correct input.j2k o.bmp"
where,
- "input.j2k" is the input corrupted JPWL codestream
- "o.bmp" this file is necessary as parameter but the decoder doesn't create
that as output.
Decoder create output file "output.j2c", that is the corrected JPWL codestream.
Note that .j2c is the extension accepted by "kakadu" decoder.

List of parameters for the coder JPEG 2000 :
Date : June the 25th, 2003
Author : Yannick Verschueren
Contact : verschueren@tele.ucl.ac.be
- the option -help displays the readme.txt file on screen
- The markers COD and QCD are writed both of two in the main_header and never appear in the tile_header. The markers in the main header are : SOC SIZ COD QCD COM.
- This coder can encode mega image, a test was made on a 24000x24000 pixels color image. You need enough disk space memory (twice the original) to encode the image. (i.e. for a 1.5 Gb image you need a minimum of 3Gb of disk memory)
REMARKS :
---------
* the value of rate enter in the code line is the compression factor !
exemple :
-r 20,10,1 means quality 1 : compress 20x, quality 2 : compress 10x and quality 3 : compress 1x = lossless
* The number of resolution can be modified by the program in view to respect profile-0 conditions (Taubman, Marcelin (2002), "JPEG2000, image compression fundamentals, standards and practice", p700)
By default :
------------
* lossless
* 1 tile
* size of precinct 2^15 x 2^15 (means 1 precinct)
* size of code-block 64 x 64
* Number of resolution : 6
* No SOP marker in the codestream
* No EPH marker in the codestream
* No sub-sampling in x and y direction
* No mode switch activated
* progression order : LRCP
* No index file
* No ROI upshifted
* No offset of the origin of the image
* No offset of the origin of the tiles
* Reversible DWT 5-3
Parameters :
------------
-i : source file (-i source.pnm also *.pgm, *.ppm) "required"
-o : destination file (-o dest.j2k) "required"
-r : different rates (-r 20,10,5) "optional"
-n : Number of resolution (-n 3) "optional"
-b : size of code block (-b 32,32) "optional"
-c : size of precinct (-c 128,128) "optional"
-t : size of tile (-t 512,512) "optional"
-p : progression order (-p LRCP) [LRCP, RLCP, RPCL, PCRL, CPRL] "optional"
-s : subsampling factor (-s 2,2) [-s X,Y] "optional"
-SOP : write SOP marker before each packet "optional"
-EPH : write EPH marker after each header packet "optional"
-M : mode switch (-M 3) [1= BYPASS(LAZY) 2=RESET 4=RESTART(TERMALL) 8=VSC 16=ERTERM(SEGTERM) 32=SEGMARK(SEGSYM)] "optional"
for several mode switch you have to add the value of each mode you want
ex : RESTART(4) + RESET(2) + SEGMARK(32) = -M 38
-x : Create an index file *.Idx (-x index_name.Idx) "optional"
-ROI:c=%d,U=%d : quantization indices upshifted for component c=%d [%d = 0,1,2]
with a value of U=%d [0 <= %d <= 37] (i.e. -ROI:c=0,U=25) "optional"
-d : offset of the origin of the image (-d 150,300) "optional"
-T : offset of the origin of the tiles (-T 100,75) "optional"
-I : Use the irreversible DWT 9-7 (-I) "optional"
IMPORTANT :
-----------
* subsampling bigger than 2 can produce error
The index file respect the structure below :
---------------------------------------------
Image_height Image_width
progression order
Tiles_size_X Tiles_size_Y
Components_nb
Layers_nb
decomposition_levels
Precincts_size_X Precincts_size_Y
Main_header_end_position
Codestream_size
Tile0 start_pos end_Theader end_pos
Tile1 " " "
...
TileN " " "
Tpacket_0 Tile layer res. comp. prec. start_pos end_pos
...
Tpacket_M " " " " " " "
