NAME

       image_to_j2k  -  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

SYNOPSIS

       image_to_j2k -i infile.bmp -o outfile.j2k

       image_to_j2k -ImgDir directory_name -OutFor jp2

       image_to_j2k -h Print a help message and exit.

              SEGMARK(32)
              Values can be added: RESTART(4) + RESET(2) + SEGMARK(32) = -M 38

       -OutFor ext
              (extension for output files)

       -POC  TtileNr=resolutionStart,  componentStart,  layerEnd,  resolutionEnd,   componentEnd,

JPWL OPTIONS

       Options usable only if the library has been compiled with -DUSE_JPWL

       -W    h<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

EXAMPLES

       image_to_j2k -i file.bmp -o file.j2k -r 20,10,1 (compress 20x, then 10x, then lossless).

       image_to_j2k -i file.ppm -o file.j2k -q 30,40,50

       image_to_j2k -i file.pgx -o file.j2k -POC T1=0,0,1,5,3,CPRL

       image_to_j2k -i lena.raw -o lena.j2k -F 512,512,3,8,u
