As is usual with questinos like this, the answer is "use Jef
Poskansker's excellent PBMPLUS package.

We'll assume you have a <w> x <h> picture, and have w*h integers
between 0 (black) and <m> (white) in the usual L-R, T-B ordering.  If
you don't hack at it until you do.

Edit such a file so that the first three lines read:

	P2
	<w> <h>
	<m>

Now say:

	ppmtogif file-with-integers > file.gif

Magic.
