NAME

       opj_jp3d_compress - Works with JPEG2000 files

DESCRIPTION

       List of parameters for the JPEG2000 Part 10 encoder: ------------

       Required Parameters (except with -h):

       -i           : source file  (-i source.bin or source*.pgx)

       -m           : source characteristics file (-m imgfile.img)

       -o           : destination file (-o dest.jp3d)

       Optional Parameters:

       -h           : display the help information

       -n           : number of resolutions (-n 3,3,3)

       -I           : use the irreversible transforms: ICT + DWT 9-7 (-I)

       -C           : coding algorithm (-C 2EB) [2EB, 3EB]

       -r           : different compression ratios for successive layers (-r 20,10,5)

              -  The  rate specified for each quality level is the desired compression factor.  -
              Rate 1 means lossless compression

              (options -r and -q cannot be used together)

       -q           : different psnr for successive layers (-q 30,40,50)

              (options -r and -q cannot be used together)

       -b           : size of code block (-b 32,32,32)

       -c           : size of precinct (-c 128,128,128)

       -t           : size of tile (-t 512,512,512)

       -p           : progression order (-p LRCP) [LRCP, RLCP, RPCL, PCRL, CPRL]

       -s           : subsampling factor (-s 2,2,2) [-s X,Y,Z]

              - Remark: subsampling bigger than 2 can produce error

       -SOP         : write SOP marker before each packet

       -EPH         : write EPH marker after each header packet

       -M           : code-block style (-M 0) [1=BYPASS(LAZY) 2=RESET 4=RESTART(TERMALL)

              8=VSC 16=PTERM 32=SEGSYM 64=3DCTXT] Indicate multiple modes by adding their values.
              ex: RESTART(4) + RESET(2) + SEGMARK(32) = -M 38

       -D           : define DC offset (-D 12)

       -x           : create an index file *.Idx (-x index_name.Idx)

       -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)

       -d           : offset of the origin of the volume (-d 150,300,100)

       -l           : offset of the origin of the tiles (-l 100,75,25)

       DEFAULT CODING: ------------

              * Lossless * 1 tile * Size of precinct : 2^15 x 2^15 x 2^15 (means  1  precinct)  *
              Size  of  code-block : 64 x 64 x 64 * Number of resolutions in x, y and z axis: 3 *
              No SOP marker in the codestream * No EPH marker in the codestream * No sub-sampling
              in  x,  y  or z direction * No mode switch activated * Progression order: LRCP * No
              index file * No ROI upshifted * No offset of the origin of the volume *  No  offset
              of  the  origin  of  the  tiles  *  Reversible  DWT  5-3  on each 2D slice * Coding
              algorithm: 2D-EBCOT

       REMARKS: ---------

       - The markers written to the main_header are : SOC SIZ COD QCD COM.  - COD and QCD markers
       will never appear in the tile_header.

       -  You  need enough disk space memory (twice the original) to encode the volume,i.e. for a
       1.5 GB volume you need a minimum of 3GB of disk memory)

       - When loading *.pgx files, a relative path to directory is needed for input argument

              followed by the common prefix of  the  slices  and  a  '*'  character  representing
              sequential numeration.

       ( -i relativepath/slices*.pgx )

              - The index file has the structure below:

              Image_height  Image_width  Image_depth  Progression  order:  0  (LRCP) Tiles_size_X
              Tiles_size_Y    Tiles_size_Z    Components_nb    Layers_nb     Decomposition_levels
