I'm currently in the process of writing a GIF print driver for my Seikosha
color graphics printer.  I have examined a GIF spec. form CompuServe and 
have a general idea how the images are encoded.  What I am still looking for
is a sample GIF file that is *very* simple to use as a test pattern and/or
learning tool.   Even better would be a document which uses a tiny GIF as
an example and lays it out byte by byte.  From what I read of the spec, the
GIF could be something like 10X10X4.  An example could be:

		R R R R R R R R R R     R = Red
		R G G G G G G G G R     B = Blue
		R G B B B B B B G R     G = Green
		R G B W W W W B G R     W = White (or Black?)
		R G B W R G W B G R
		R G B W B W W B G R
                R G B W W W W B G R
		R G B B B B B B G R
		R G G G G G G G G R
		R R R R R R R R R R

If could help me build a byte by byte GIF file for the above example, or
you know of a tiny GIF which already exists (Hopefully accessable with CIS)
I will place you in my list of Saint-hood individuals and give you your share
of $cash$ when I hit the big Lotto number...  Thanks. Lmm
