GIF2NDF

Converts a GIF file into an NDF.

Description:

This Bourne-shell script converts a Graphics Interchange Format (GIF) file into an unsigned-byte (256 grey-level) NDF format file. It handles one- or two-dimensional images. The script uses various NETPBM utilities to produce a FITS file, flipped top to bottom, and then FITS2NDF to produce the final NDF. Error messages are converted into Starlink style (preceded by !).

Usage:

gif2ndf in [out]

Parameters:

IN = FILENAME (Read)
The name of the GIF file to be converted. (A .gif name extension is assumed if omitted.)
OUT = NDF (Write)
The name of the NDF to be generated (without the .sdf extension). If the OUT parameter is omitted, the value of the IN parameter is used.

Examples:

gif2ndf old new
This converts the GIF file old.gif into an NDF called new (in file new.sdf).
gif2ndf horse
This converts the GIF file horse.gif into an NDF called horse (in file horse.sdf).
