GIF2TIFF(1)                                                        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 (Compression=5).  These characteristics can over-
       riden, 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 compres-
              sion 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.
