Well, ghostscript is a postscript interpreter, and postscript is just a stack-based language.<div>I'd take a look at the Barcodewriter stuff anyways. He did a good job abstracting it out and it supports a lot of different barcodes.</div>
<div>Basically you set up the parameter, and say "go generate it!" When it comes back to give it a cookie and a pat on the head.</div><div>Even if you don't use it initially it's always nice to have options... :)</div>

<br>Antoine and Mike: I've read some good things on Barcodewriter. However, some flexibility in the output is required here, and if we're going for several kinds of image generation then ghostscript and PS output are extra components on the chain that we have no "use" for. In any case, thanks for pointing us to a cool solution.<br>

Curious. Must be the zeitgeist.<br>
<br>
I recently finished a qrcode implementation in Erlang, to enable 2-<br>
factor authentication using the Google Authenticator mobile app on a<br>
phone.<br>
<br>
I wasn't planning to, but I guess I could be convinced to open source<br>
it on GitHub... though right now, although it's sufficient for our<br>
needs, I'm making no big claims over performance ;)<br>
<br>
I can tell you that if you decide to write an implementation yourself,<br>
google's zxing java/cpp code is a good reference.<br>
