RAW2TIFF(1)		    General Commands Manual		   RAW2TIFF(1)

NAME
       raw2tiff	- create a TIFF	file from a raw	data

SYNOPSIS
       raw2tiff	[ options ] input.raw output.tif

DESCRIPTION
       raw2tiff	 converts a raw	byte sequence into TIFF.  By default, the TIFF
       image is	created	with data samples packed (PlanarConfiguration=1), com-
       pressed	with the PackBits algorithm (Compression=32773), and with each
       strip no	more than 8 kilobytes.	These characteristics can  overridden,
       or explicitly specified with the	options	described below.

OPTIONS
       -H number
	      size  of	input  image file header in bytes (0 by	default). This
	      amount of	data just will be skipped from the start of file while
	      reading.

       -w number
	      width of input image in pixels (can be guessed, see GUESSING THE
	      IMAGE GEOMETRY below).

       -l number
	      length of	input image in lines (can be guessed, see GUESSING THE
	      IMAGE GEOMETRY below).

       -b number
	      number of	bands in input image (1	by default).

       -d data_type
	      type of samples in input image, where data_type may be:
	      byte     8-bit unsigned integer (default),
	      short    16-bit unsigned integer,
	      long     32-bit unsigned integer,
	      sbyte    8-bit signed integer,
	      sshort   16-bit signed integer,
	      slong    32-bit signed integer,
	      float    32-bit IEEE floating point,
	      double   64-bit IEEE floating point.

       -i config
	      type  of	samples	 interleaving in input image, where config may
	      be:
	      pixel   pixel interleaved	data (default),
	      band    band interleaved data.

       -p photo
	      photometric interpretation (color	space)	of  the	 input	image,
	      where photo may be:
	      miniswhite   white color represented with	0 value,
	      minisblack   black color represented with	0 value	(default),
	      rgb	   image has RGB color model,
	      cmyk	   image has CMYK (separated) color model,
	      ycbcr	   image has YCbCr color model,
	      cielab	   image has CIE L*a*b color model,
	      icclab	   image has ICC L*a*b color model,
	      itulab	   image has ITU L*a*b color model.

       -s     swap bytes fetched from the input	file.

       -L     input data has LSB2MSB bit order (default).

       -M     input data has MSB2LSB bit order.

       -c     Specify  a compression scheme to use when	writing	image data: -c
	      none for no compression, -c packbits for the  PackBits  compres-
	      sion algorithm (the default), -c jpeg for	the baseline JPEG com-
	      pression algorithm, -c zip for  the  Deflate  compression	 algo-
	      rithm, and -c lzw	for Lempel-Ziv & Welch.

       -r number
	      Write data with a	specified number of rows per strip; by default
	      the number of rows/strip is selected so that each	strip  is  ap-
	      proximately 8 kilobytes.

GUESSING THE IMAGE GEOMETRY
       raw2tiff	 can guess image width and height in case one or both of these
       parameters are not specified. If	you omit one of	those parameters,  the
       complementary  one  will	 be  calculated	based on the file size (taking
       into account header size, number	of bands and data type). If  you  omit
       both  parameters,  the  statistical approach will be used. Utility will
       compute correlation coefficient between two lines at the	 image	center
       using  several appropriate line sizes and the highest absolute value of
       the coefficient will indicate the right line  size.  That  is  why  you
       should be cautious with the very	large images, because guessing process
       may take	a while	(depending on your system performance).	Of course, the
       utility	can't guess the	header size, number of bands and data type, so
       it should be specified manually.	If you don't know anything about  your
       image, just try with the	several	combinations of	those options.

       There  is  no magic, it is just a mathematical statistics, so it	can be
       wrong in	some cases. But	for most ordinary images guessing method  will
       work fine.
