 # code2png - Render code to an image on OS X
 # Peter Cooper (@peterc)
 # MIT license
 #
 # code2png converts source code into a PNG graphic
 # (with syntax coloring, if you want). Ideal for
 # Kindle document production, RSS feeds, etc.
 #
 # Tweak the embedded HTML to improve the CSS for your
 # taste, and include Pygments' CSS to colorize the
 # syntax highlighting if you want. Remove the
 # max-height stuff if you hit length issues, I needed
 # it for Kindle reasons :-)
 #
 # NOTE: I *KNOW* that Pygments can do graphics exporting
 # of its own but trying to install Python Imaging Library
 # made installing rmagick in Ruby back in 2007 look easy
 # so I gave up and cobbled this together. Plus I'm guessing
 # WebKit's Quartz text rendering is better than PIL.
 #
 # Usage:
 #
 #   ruby code2png.rb source_file.rb
 #
 # Dependencies:
 #   OS X
 #   Pygments (sudo easy_install Pygments)
