## 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 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 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.

## 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.
