.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
|
1999-07-27 17:50:26 -04:00
|
|
|
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.
