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

OPTIONS
       -b  n,n
	      (Size of code block (e.g. -b 32,32). Default: 64 x 64)

       -cinema2K  fps
	      Digital Cinema 2K profile compliant codestream. Valid fps values are 24 or 48.

       -cinema4K
	      Digital Cinema 4K profile compliant codestream. Does not need an fps: default is 24
	      fps.

       -d  X,Y
	      (Offset of image origin (e.g. -d 150,300))

       -h     Print a help message and exit.

       -o  name
	      (output file name)

       -p  name
	      Progression order. name can be one out of:LRCP, RLCP, RPCL,  PCRL,  CPRL.  Default:
	      LRCP.

       -q  n  different psnr for successive layers
	      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 factor.
	      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,  pro-
       gressionOrder
	      (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
