j2k_to_image(1) 	     converts jpeg2000 files		 j2k_to_image(1)

NAME
     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 .

SYNOPSIS
     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

OPTIONS
     -i name
	    (jpeg2000 input file name)

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

     -o name
	    (output file name with extension)

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

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

     -ImgDir directory_name
	    (directory containing input files)

     -OutFor ext
	    (extension for output files)

JPWL OPTIONS
     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; de-
     fault:3)

     -W t[=Nt] (Nt is the maximum number of tiles in the codestream; de-
     fault:8192)

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

REDUCTION
     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 dis-
     carded levels. The reduce factor is limited by the smallest total number of
     decomposition levels among tiles.

TILES
     Set the maximum number of quality layers to decode. If there are less qual-
     ity layers than the specified number, all the quality layers are decoded.
