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 below)

       -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; default:3)

       -W t[=Nt] (Nt is the maximum number of tiles in the codestream; default: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 discarded 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 quality layers than the specified number, all the quality layers  are
       decoded.
