.SH NAME
|
|
gif2tiff \- create a
|
|
.SM TIFF
|
|
file from a GIF87 format image file
|
|
.SH SYNOPSIS
|
|
.B gif2tiff
|
|
[
|
|
.I options
|

]
|
|
.I input.gif
|

.SH DESCRIPTION
|
|
.I Gif2tiff
|
|
converts a file in the GIF87 format to
|
|
.SM TIFF.
|
|
The
|
|
.SM TIFF
|
|
image is created as a palette image, with samples
|
|
compressed with the Lempel-Ziv & Welch algorithm (\c
|
|
.IR Compression =5).
|
|
These characteristics can overridden, or explicitly specified
|
|
with the options described below.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-c
|
|
Specify a compression scheme to use when writing image data:
|
|
.B "\-c none"
|
|
for no compression,
|
|
.B "\-c packbits"
|
|
for the PackBits compression algorithm,
|
|
.B "\-c zip"
|
|
for the Deflate compression algorithm,
|
|
and
|
|
.B "\-c lzw"
|
|
for Lempel-Ziv & Welch (the default).
|
|
.TP
|
|
.B \-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.
|
|
.SH NOTES
|
|
The program is based on Paul Haeberli's
|
|
.I fromgif
|
|
program which, in turn, is based on Marcel J.E. Mol's GIF reader.
|
|
.SH BUGS
|
|
Should have more options to control output format.
