Would it be possible to add support for QRCode ?
Your project is great !
The QRCode will be great.
It may be so interesting!!
We need QR code too. It is very popular. It would be great if it can be supported.

I would second the request too. Eventually Java code from here could be used: http://code.google.com/p/zxing/ It is also Apache licensed, so reuse seems possible.
Implementing QR Code is a larger piece of work and the specification also has to be paid for. So, for me to work on this I'd need one or more parties to fund the development. I'm very reluctant to fork code from ZXing especially when I don't even have the specification to verify what I'm doing. But you can always use ZXing directly to produce QR Code.
I've implemented basic support for QR Code by using ZXing (see CVS HEAD). Basically, I've just written an adapter so the ZXing QR encoder can be used with the Barcode4J API. So ZXing's limitations for QR Code will also be Barcode4J's limitations. For this to work, ZXing Code 1.7 or later has to be in the classpath. That dependency is optional but without ZXing in the classpath, QR Code will obviously not be available. Feedback welcome.
