GIF2TIFF(1)                          General Commands Manual                          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 pal-
       ette image, with samples compressed with the Lempel-Ziv & Welch algorithm (Compression=5).
       These  characteristics  can overridden, or explicitly specified with the options described
       below.

OPTIONS
       -c     Specify a compression scheme to use when writing image data: -c none  for  no  com-
              pression,  -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.
