Re: [GTALUG] Software to draw illustrations?

If you can write Forth, you can write PS.

I also generate PS with other programs.

Exactly. I'd used it as a poor-mans CAD package ( http://melwilsonsoftware.ca/psfiles/whitenoise-panel.ps ). It's an excellent way to get pixel-level control of printed matter, and that's around 1/300" on ink-jet printers. For my big use, membership cards from a database, it was Python program->Postscript program->Ghostscript rendering->printer. Your favorite HLL could replace Python.
