Re: [Matplotlib-users] Using RendererAgg with windows

[jim <jl...@yv...>]

John:

What I need to do is create drawings of windows (as in plug holes in houses 
and let in light) with grid and other options on the fly.

So what I need are the graphic primitives -- canvas, lines, fills ...
The output needs to be a graphic file.  

I will go back and study the docs, but a suggestion of what area to use would 
be most welcome.  Or, of course, a different module than matplotlib if that 
would be more appropriate.

Thanks,
Jim
