NAME

gif2tiff − create a <small>TIFF</small> file from a

GIF87 format image file

SYNOPSIS

       cols="2" cellspacing="0" cellpadding="0">

gif2tiff [ options ] input.gif

output.tif

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

Gif2tiff converts a file in the GIF87 format to

<small>TIFF.</small> The <small>TIFF</small> 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

       cols="5" cellspacing="0" cellpadding="0">

−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

       cols="2" cellspacing="0" cellpadding="0">

The program is based on Paul Haeberli’s

fromgif program which, in turn, is based on Marcel

J.E. Mol’s GIF reader.

BUGS

       cols="2" cellspacing="0" cellpadding="0">

Should have more options to control output format.
