J2K_TO_IMAGE(1) 						  OPENJPEG TOOLS						   J2K_TO_IMAGE(1)

NAME

       j2k_to_image - convert a J2K, JP2 or JPT file into a PGM, PPM, PNM, PGX or BMP file

SYNOPSIS

       j2k_to_image -i source -o destination [-r reduction] [-l layers]

       j2k_to_image -ImgDir sourcedir -OutFor extension [-r reduction] [-l layers]

       j2k_to_image -h

DESCRIPTION

       j2k_to_image decodes a JPEG 2000-encoded image into another image format

OPTIONS

       -ImgDir sourcedir
	   Directory of J2K, JP2 or JPT files to convert

       -OutFor extension
	   PGM, PPM, PNM, PGX or BMP output file format

       -i source
	   J2K, JP2 or JPT file to convert

       -o destination
	   PGM, PPM, PNM, PGX or BMP file to output to

       -h  Display help information

       -r reduction
	   Number of highest resolution levels to be discarded. Output resolution is effectively divided by 2^reduction

       -l layers
	   Maximum count of quality layers to decode

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.
