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 sam-
ples 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
Should have more options to control output format.
