I would like to create Design QR codes with Java.
Design QR codes may contain a logo in form of a graphic. Here's an example for such designed codes.
How to create such QR codes?
I just found a software that makes it possible to create such QR codes.
There's a different way to put pictures in QR codes. Instead of scribbling on redundant pieces and relying on error correction to preserve the meaning, we can engineer the encoded values to create the picture in a code with no inherent errors, like these:
The software is developed in Go and available via https://github.com/skatiyar/qr (mirror, as Google Code went down)
The author describes it en detail under http://research.swtch.com/qart
Alternatives are e.g. Awesome QR:
