var Canvas = require('Canvas').Canvas;
Server-side implementation of Canvas rendering object.
The browser side implementation of Canvas allows dynamic rendering to and interaction with images. This server-side implementation allows for the rendering of static images using the same API.
For complete details on the browser-side Canvas API, see http://www.w3.org/TR/2dcontext/.
var canvas = new Canvas(width, height);
var context = canvas.getContext('2d');
The Canvas API is implemented on top of SilkJS' native libcairo methods.
The only two context2d methods not implemented are createImageData() and putImageData(), otherwise this is a complete API.
Garbage collection is an issue, since libcairo objects are instantiated by the Canvas API that need to be freed/released. For this reason, the Image, CanvasRenderingContext2D, and Canvas classes all have destroy() methods that you should call when you are done using those objects.
The Canvas object implements some garbage collection for patterns. Those are destroyed() automatically when you call the canvas' destroy() method.
In addition to the destroy() methods, the Canvas.writeToFile(path) method is implemented to save your rendered canvas to a PNG file.
