Correct me if I'm wrong, but don't you have the x and y variables named the wrong way around in that example code?

The method is is_dark( row, col ), so it really should be a y loop containing an x loop, with @qr.dark?(y,x) instead.

It is exactly so. I've been questioning myself why my QR codes can not be read by any device and you solved the mystery for me :) Flipping the x,y from example and using .dark?(y,x) instead did indeed make my QRs readable. Thank you @vdh! Glad I found this issue...

I had the same issue...fixed by switching x & y

I have changed the example so this is no longer a problem.
