+This directory contains a subset of the OpenJPEG project (http://www.openjpeg.org/)
+The OpenJPEG library is an open-source JPEG 2000 codec written in C language. It
+has been developed in order to promote the use of JPEG 2000, the new still-image
+compression standard from the Joint Photographic Experts Group (JPEG). In
+addition to the basic codec, various other features are under development, among
+them the JP2 and MJ2 (Motion JPEG 2000) file formats, an indexing tool useful
+for the JPIP protocol, JPWL-tools for error-resilience, a Java-viewer for
+j2k-images, ...
+
+The library is developed by the Communications and Remote Sensing Lab (TELE),
+in the Université Catholique de Louvain (UCL).
+
+The OpenJPEG library is released under the BSD license (see BSDlicense.txt for
+details). Or online at:
+http://www.tele.ucl.ac.be/PROJECTS/OPENJPEG/BSDlicense.txt
+
+We only include enough of distribution to build libopenjpeg. We temporarily
+include the codec subdirs, just for developers. This allow us to build the
+standalone executable in case we'll ever need to debug a problematic j2k stream.
+Furthermore, the standard OpenJPEG build process is replaced with a CMake build
+process.
+
+We'd like to thank the OpenJPEG project for releasing an open source
+implementation of the JPEG2000 codec. In particular, thanks to Antonin Descampe
+for fixing the 'well known' 16bits j2k issue.
+
+Modifications
+-------------
+
+- modification were made so that compilation with gcc -Wall flags passes without warnings
+- remove all explicit tabs and replace by proper amount of spaces
+- remove all Makefile, *.dsp files

+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 !

+-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 " " "

+ * The better performance is caused by doing the 1-dimensional DWT
+ * within a temporary buffer where the data can be accessed sequential
+ * for both directions, horizontal and vertical. The 2d vertical DWT was
+ * the major bottleneck in the former version.
+ *
+ * I have also removed the "Add Patrick" part because it is not longer
+ * needed.
