That's pretty much the code I used. In fact, I borrowed it from the pdf. I 
just tried it, and it output "%PNG".

I'd like to see this displayed in a window. If the fine had written 
properly, I could see whether it really drew the lines. It did not fail on 
the same draw stmts in my program.

I see my problem, , instead of + between the tuples. I thought I'd seen 
another example where the 2-d tuples could be separated.

I see a ImageFile module, but it's not for writing image files simply.
