GIF2TIFF(1)              USER COMMANDS                GIF2TIFF(1)

NAME

     gif2tiff - create a TIFF file from a GIF87 format image file

SYNOPSIS

     gif2tiff [ options ] input.gif output.tif

DESCRIPTION

     Gif2tiff converts a file in the GIF87 format  to  TIFF.  The
     TIFF  image  is  created  as  a  palette image, with samples
     compressed with the Lempel-Ziv & Welch  algorithm  (Compres-
     sion=5).  These characteristics can overriden, or explicitly
     specified with the options described below.

OPTIONS

     -c   Specify a compression scheme to use when writing  image
          data:   -c none for no compression, -c packbits for the
          PackBits compression algorithm, -c zip for the  Deflate
          compression  algorithm,  and  -c  lzw  for Lempel-Ziv &
          Welch (the default).

     -r   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.

NOTES

     The program is based  on  Paul  Haeberli's  fromgif  program
     which, in turn, is based on Marcel J.E. Mol's GIF reader.

BUGS

     Should have more options to control output format.
