Show HN: Generating a HTML QR code

Works fine as long as you don't want to generate new QR codes when you're offline. I have to admit, if you're intending to generate QR codes only online, the charts api is the better way to go, since it's more likely to have users with JavaScript disabled than users with image tags disabled g
On Chrome 15 Win there seems to be some tiles alignment issue when browser zoom is set to something else than the default value. On the other hand recent FF and IE render just fine.
saving the qr code doesn't add the .png extension (it just downloads a "download" file, not "download.png"). I'm using Chrome 15 on Win7.
Hey! I know and I also know that this isn't nice.
It is because QR-Designer is using the HTML Canvas' toDataURL function to save the image. The download then gets initiated by setting the dataurl as the document.location.href. Unfortunately I can't control the file name with that technique. I'd really appreciate any hints on how to solve that better (without a server)
