image_to_j2k(1)		  converts to jpeg2000 files	       image_to_j2k(1)

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.

       See JPWL	OPTIONS	for special options

	      Note: (options -r	and -q cannot be used together)

       -r  n  different	compression ratio(s) for successive layers.  The  rate
	      specified	for each quality level is the desired compression fac-
	      tor.
	      Note: (options -r	and -q cannot be used together)

       -s  X,Y
	      sub-sampling factor (e.g.	-s 2,2). Default: No sub-sampling in x
	      or y direction.
	      Remark: sub-sampling bigger than 2 can produce errors.

       -t  W,H
	      (Size of tile (e.g. -t 512,512) )

       -x  name
	      (Create index file and fill it. Default: no index	file)

       -EPH   (Write EPH marker	after each header packet. Default:no EPH)

       -F  rawWidth,rawHeight,rawComp,rawBitDepth,s_or_u
	      characteristics of the raw input image

       -I     (Use the irreversible DWT	9-7. Default: Reversible DWT 5-3)

       -ImgDir	directory_name
	      (directory containing input files)

       -M  n  mode  switch  with  values:  1, 2, 4, 8, 16, 32. Default:No mode
	      switch activated.
	      Meaning:
	      BYPASS(1)
	      RESET(2)
	      RESTART(4)
	      VSC(8)
	      ERTERM(16)
	      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, progressionOrder
	      (see Examples)

       -ROI c=n,U=n
	      quantization  indices  upshifted	for  component c (0 or 1 or 2)
	      with a value of U	(>= 0 and <= 37)
	      e.g. -ROI	c=0,U=25

       -SOP   (Write SOP marker	before each packet. Default: No	SOP marker  in
	      the codestream.)

       -T X,Y (Offset of the origin of the tiles (e.g. -T 100,75) )

       -W     (see JPWL	OPTIONS)

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
