RAW2TIFF(1)                                                        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),
       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.

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
              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.

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.
