= OilyPNG

OilyPNG is a Ruby C extension to speed up the pure Ruby ChunkyPNG library. 

Currently it has an alternative implementation of decoding PNGs, making that operation much 
faster for PNG images that apply filtering. An alternative implementation for encoding is
planned.

*Warning*: this is my first C code in years. It may blow up your PC after leaking memory all
over the place, killing a kitten in the process. You have been warned.

== Usage

1. First install the gem and make it available to your project.
2. Use require "oily_png" instead of require "chunky_png"
3. Presto! Now use ChunkyPNG as you normally would and get an instant speedup. 

See http://github.com/wvanbergen/chunky_png/wiki for more information on how to use the
ChunkyPNG API.
