j2k_to_image(1)             converts jpeg2000 files            j2k_to_image(1)


       j2k_to_image  -  This program reads in a jpeg2000 image and converts it
       to another image type. It is part of the OpenJPEG library.

       Valid input image extensions are .j2k, .jp2, .j2c, .jpt

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


       j2k_to_image -i infile.j2k -o outfile.png

       j2k_to_image -ImgDir images/ -OutFor bmp

       j2k_to_image -h Print help message and exit

       See JPWL OPTIONS for special options


       -i name
              (jpeg2000 input file name)

       -l n   n  is the maximum number of quality layers to decode. See LAYERS

       -o name
              (output file name with extension)

       -r n   (n is the highest resolution level to be discarded.  See  REDUC-
              TION below)

       -x name
              (use name as index file and fill it)

       -ImgDir directory_name
              (directory containing input files)

       -OutFor ext
              (extension for output files)


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

       -W  c[=Nc]  (Nc is the number of expected components in the codestream;

       -W  t[=Nt]  (Nt  is  the  maximum  number  of  tiles in the codestream;

       -W c[=Nc], t[=Nt] (same as above)


       Set the number of highest resolution levels to be discarded.  The image
       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.


       Set the maximum number of quality layers to decode. If there  are  less
       quality  layers  than  the specified number, all the quality layers are
