PNGQR (Ping-queer?) ------------------- Pure Ruby Gem to generate PNG files of QR codes. Usage ----- Example: require 'pngqr' Pngqr.encode 'https://github.com/andys', :file => 'output.png' The parameters for encode() are the same as the rqrcode gem's new(), except: 1. we add :file if you want to output to a file instead of returning the PNG as a blob, and 2. you can :scale with an integer parameter and it will scale up the output image by that many times. 3. if you don't supply a :size, we auto-size by testing each size until we find the one that worked. It seems quick enough. 4. :border=>n lets you add an n pixel white border to the PNG Dependencies ------------ Gems: rqrcode and chunky_png (both pure ruby gems) See: http://whomwah.github.com/rqrcode/ Contact the author ------------------ Andrew Snow <andrew@modulus.org> Andys^ on irc.freenode.net @andy_snow on the twitter
