n.b. this is a recreation of another composition as the original (http://dasaq.wordpress.com/2009/07/01/qrcode-gen/) is no longer online. I originally wanted to recreate it as a CoreImage filter, but gave up as I couldn't find out how to treat a structure as an image for the sampler.

Clever work, both the original and your translated re-versioning.

Great job ! I was trying to make a javascript barcode generator and wasn't able to do it.

Haven't tested very long yet your comp, but I have a bug on the "Number" mode : code lenght overflow.

Thanks for this !

Hey, I know this comment's quite old, but are you able to recreate this bug? What steps can you take to get the error message?

Hi,

I write 'http://www.carasuelo.org/' (without quotes) in the text field

Then I pass to 'Number Mode' while the viewer is on, and I have these messages :

23:57:12.134 ["QRCode Generator" @ "QR Code"] > Execution failed at time 28.848

23:57:12.352 ["Macro Patch" @ "(null)"] > Rendering terminated on

I work on 10.6.6 on a MBP 13" in 64bit mode.

Hope this helps...
