       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.
