- I have done something similar, and I am not sure
- if "aspect ratio" is really key. The real problem with the interchange
- of ascii pics is that the font used in the rendering process may bear
- little resemblance to that used by other people's displays.
-
- I have settled on a simple 9x7 font, which is approximated by most dumb
- terminals (and printers, dont forget), and is available to X terminals.
- I suppose the right thing to do is to let the user of the rendering
- program select a font description in rendering which matches his current
- display - but I don't know how best to do that :-{

- As I said, I'm not sure if it will help that much.

- Nice pic, by the way - how many characters in the set do you use?
