gif2tiff - create a TIFF file from a GIF87 format image file
gif2tiff [ options ] input.gif output.tif
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
overridden, or explicitly specified with the options described below.
-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.
The program is based on Paul Haeberli's fromgif program which, in turn,
is based on Marcel J.E. Mol's GIF reader.
Should have more options to control output format.
