Ichabod is a server process which accepts POSTed HTML and can rasterize (eg. render images) and evaluate JS in that HTML document. There is a focus on rendering speed.

• Fast rasterization of HTML. See the getting started section and the benchmarks.
• JSON API See the API documentation.
• Javascript interface for rasterization functions
• Animated output using giflib. See some example usage.
• High quality animated output using mediancut and other diffusion methods.
• Python bindings. See the python bindings and the iPython walkthrough.
• X11 not required.
• statsd support built in.

Output:

Ichabod utilizes webkit (from Qt) to render HTML and evaluate JavaScript, and mongoose to parse incoming requests and return responses. Other libraries are used for high-quality animated gif support.
