Every so often I want to quickly sketch out what should be a simple diagram. Irrespective of what drawing program I use, I always seem to take much more time than I intend for a result that does not even remotely resemble what I want.
So I decided to give up and find a way to use hand-drawn sketches instead. Here’s the method I ended up with, based almost entirely on Marc Liberatore’s "Whiteboard Diagrams as PDFs" post and the wonderful ImageMagick and Potrace utilities.
My drawings still look fairly terrible, but at least they convey what I want them to and are quick to produce! :)
