I want to create a custom QR code.
When you say you "want to create
a custom QR code" do you mean just
one (or only a few) of your own domain URL, or
many, as in lots of QR codes, each with different information in them?
Other wonderings are: What is the QR code to be used for? The rounded QR code sample you've provided looks good, but gut instinct tells me that it will be less reliable than the traditional style. How important is looks vs functionality in your use case?
