NAME

       opj_jp3d_decompress - decompress jp3d files

SYNOPSIS

       opj_jp3d_decompress  [optional  arguments]  -i  input.{jp3d,  j3d} -o output.{pgx, bin} -m
       characteristics.img

OPTIONS

   Required Parameters (except with -h):
       -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 arguments
       -h

       -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.
