http://potrace.sourceforge.net/ http://potrace.sourceforge.net/ but we weren't talking about bitmaps. I have no doubt that a trained typographer can identify fonts at 100 paces in a hurricane, but if he sees his font in printed material, contacts the publisher and says "That's my font" and the publisher says "No it's not" what is his recourse? He'd have to get some kind of order to search the publisher, or otherwise demand that the publisher prove that its a different font. How do you convince a judge that two fonts are the same, without superimposing them? Does "Look at the serifs!" hold up? I'm not saying that its impossible to prove the origin of a font, just that it gets a lot harder once you leave the digital world.
