       raw2tiff - create a TIFF file from a raw data

       raw2tiff [ options ] input.raw output.tif

       raw2tiff  converts  a  raw byte sequence into TIFF.  By default, the TIFF image is created
       with data samples packed (PlanarConfiguration=1), compressed 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.

       -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

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

       -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 com-
	      pression, -c packbits for the PackBits compression algorithm (the default), -c jpeg
	      for  the	baseline  JPEG	compression algorithm, -c zip for the Deflate compression
	      algorithm, 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 approximately 8 kilobytes.

       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 man-
       ually. 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.
