NAME

       opj_jp3d_decompress - Works with JPEG2000 files

DESCRIPTION

       HELP ----

       - the -h option displays this help information on screen

       List of parameters for the JPEG 2000 encoder:

              Required arguments ----------------------------

       -i <compressed file> ( *.jp3d, *.j3d )

              Currently accepts J3D-files. The file type is identified based on its suffix.

       -o <decompressed file> ( *.pgx, *.bin )

              Currently  accepts  PGX-files and BIN-files. Binary data is written to the file (not ascii).  If a
              PGX filename is given, there will be as many output files as slices; an  indice  starting  from  0
              will then be appended to the output filename, just before the "pgx" extension.

       -m <characteristics file> ( *.img )

              Required only for BIN-files. Ascii data of volume characteristics is written.

              Optional ----------------------------

       -h

              Display the help information

       -r <RFx,RFy,RFz>

              Set  the  number  of  highest  resolution  levels  to  be discarded on each dimension.  The volume
              resolution is effectively divided by 2 to the power of the number of discarded levels. The  reduce
              factor is limited by the smallest total number of decomposition levels among tiles.

       -l <number of quality layers to decode>

              Set  the  maximum  number  of  quality layers to decode. If there are less quality layers than the
              specified number, all the quality layers are decoded.

       -O original-file

              This option offers the possibility to compute some quality results for  the  decompressed  volume,
              like  the  PSNR  value  achieved  or  the  global SSIM value.  Needs the original file in order to
              compare with the new  one.   NOTE:  Only  valid  when  -r  option  is  0,0,0  (both  original  and
              decompressed  volumes  have  same  resolutions)  NOTE:  If  original file is .BIN file, the volume
              characteristics file shall  be  defined  with  the  -m  option.   (i.e.  -O  original-BIN-file  -m
              original-IMG-file)

       -BE

              Define  that  the  recovered  volume  data  will be saved with big endian byte order.  By default,
              little endian byte order is used.
