opj_jp3d_decompress - Works with JPEG2000 files
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.
