I would like to share the encoding process for QR code that I have discovered so far by reading ZXing's code and ISO/IEC document. So people could read and give feed back. Also I have list some issue we currently have. Those issue you won't notice from QR-CodeControl,
as it is still under ZXing code wrapper. Thus this is just for development reference.
Here is document link.
Also for future decode part. I have found this framework. It might be useful, I will list it here for future reference. It's C# AI framework, and it has a lot of image process and detection function. It should be useful to detect un-expect or damaged
QR code picture.
