We want a QR for several URLs on Facebase, including for the 6 movies found here:

genomebrowser.facebase.org/testing11/

QR codes are those things we see everywhere on ads that let mobile phone/camera users snap to take them to a URL. We want them for Facebase posters.

This ruby code creates png formatted images of the QR codes. It also dumps text which can be used to create an HTML/CSS version of the QR code:

qrHTMLandPNGmaker.rb

That ruby doesn't actually dump HTML, only text with and 'x' character for dark and a "space" character for light. That text output can be used to create HTML/CSS that displays the QR code as an HTML table. This python program reads the output from the ruby program (the text output) and writes HTML/CSS to generate the QR code:

qrHTMLmaker.py

The ruby requires some modules that are probably not present. Install them with gem like this:

gem install rqrcode

gem install rqrcode_png

NOTICE that the URLs are hardcoded into the ruby.

NOTICE that the file qr.txt produced by the ruby is a hardcoded input filename in the python.

The whole thing was run like this:

ruby qrHTMLandPNGmaker.rb > rb.txt

python qrHTMLmaker.py > qr_codes.html

After running the ruby program, six new 300x300 PNG-formatted images will be created in the current directory. The output HTML from the python can be dropped right into any HTML file and will display the QR codes.
