       Options usable only if the library has been compiled with -DUSE_JPWL-Wh<tilepart><=type>,s<tilepart><=method>,a=<addr>,z=<size>,g=<range>,p<tilepart:pack><=type>h selects the header error protection (EPB): type can be
          [0=none 1,absent=predefined 16=CRC-16 32=CRC-32 37-128=RS]
          if tilepart is absent, it is for main and tile headers
          if tilepart is present, it applies from that tile
            onwards, up to the next h<> spec, or to the last tilepart
            in the codestream (max. 16 specs)

       p selects the packet error protection (EEP/UEP with EPBs)
         to be applied to raw data: type can be
          [0=none 1,absent=predefined 16=CRC-16 32=CRC-32 37-128=RS]
          if tilepart:pack is absent, it is from tile 0, packet 0
          if tilepart:pack is present, it applies from that tile
            and that packet onwards, up to the next packet spec
            or to the last packet in the last tilepart in the stream
            (max. 16 specs)

       s enables sensitivity data insertion (ESD): method can be
          [-1=NO ESD 0=RELATIVE ERROR 1=MSE 2=MSE REDUCTION 3=PSNR
           4=PSNR INCREMENT 5=MAXERR 6=TSE 7=RESERVED]
          if tilepart is absent, it is for main header only
          if tilepart is present, it applies from that tile
            onwards, up to the next s<> spec, or to the last tilepart
            in the codestream (max. 16 specs)

       g determines the addressing mode: range can be
          [0=PACKET 1=BYTE RANGE 2=PACKET RANGE]

       a determines the size of data addressing: addr can be
          2/4 bytes (small/large codestreams). If not set, auto-mode

       z determines the size of sensitivity values: size can be
          1/2 bytes, for the transformed pseudo-floating point value

       opj_compress - This program reads in an image of a certain type and converts it to a jpeg2000 file. It is
       part of the OpenJPEG library.

       Valid input image extensions are .bmp,.pgm,.pgx,.png,.pnm,.ppm,.raw,.tga,.tif . For PNG resp. TIF
       it needs libpng resp. libtiff .

       Valid output image extensions are .j2k,.jp2

-bn,n
              (Size of code block (e.g. -b 32,32). Default: 64 x 64)

       -cn  (Size of precinct (e.g. -c 128,128). Default: 2^15 x 2^15)

       -cinema2Kfps
              Digital Cinema 2K profile compliant codestream. Valid fps values are 24 or 48.

       -cinema4K
              Digital Cinema 4K profile compliant codestream. Does not need an fps: default is 24 fps.

       -dX,Y
              (Offset of image origin (e.g. -d 150,300))

       -h     Print a help message and exit.

       -qn  different psnr for successive layers
              Note: (options -r and -q cannot be used together)

       -rn  different compression ratio(s) for successive layers. The rate specified for each quality level is
              the desired compression factor.
              Note: (options -r and -q cannot be used together)

       -sX,Y
              sub-sampling factor (e.g. -s 2,2). Default: No sub-sampling in x or y direction.
              Remark: sub-sampling bigger than 2 can produce errors.
