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 overriden, 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.
