Frank Krueger published a new open source graphics library called NGraphics today. As with everything Frank does it looks pretty awesome. It even has its own editor where you can type in code and live preview the output. So you probably won’t need what I’m about to show you, but I was curious if it would work with Xamarin Sketches (just for kicks).

Sure enough, all I had to do was add LoadAssembly calls to reference NGraphics assemblies in the sketch and add the assemblies to the sketchname.sketchcs.Resources folder alongside the sketchcs file. Then, since Frank includes methods to return native image types, such as NSImage on Mac, I can leverage the sketch visualizers in Xamarin Studio to get a live preview.

Here’s Frank’s sample code to draw a house in a sketch:
