  Can someone tell me enough PostSript to send a bit map to the LaserWriter?
I'm downloading digitized images from a VAX.  I've examined a PostScript file
from MacPaint (using a command-F) and it looks fairly easy:

	md begin
	1320 od
	(; user: )jn
	%%EndProlog
	%%Page: ? ?
	op
	0 0 moveto
	578 3 0 133 74 578 3 F 1 dobits
	00...
	578 20 0 148 74 578 20 F 1 dobits
	00...
	578 18 0 168 74 578 18 F 1 dobits
	00...
	578 18 0 168 74 578 18 F 1 dobits
	00...
	page
	cp
	%%Trailer
	end

The command of interest seems to be "dobits."  I need to know what the specific
commands are doing.  A pointer to a simple reference on PostScript would also
be helpful.

Thanks,
