RenderingContext

    RenderingContext

The rendering context of a canvas object.

Must be obtained via one of the following:

• The Canvas.getContext('2d') interface returns a CanvasRenderingContext2D object
• The Canvas.getContext('webgl') or Canvas.getContext('experimental-webgl') interface returns a WebGLRenderingContext object
• The Canvas.getContext('webgl2') or Canvas.getContext('experimental-webgl2') interface returns a WebGL2RenderingContext object

2d interface support:

Supports most of the properties and methods defined by HTMl Canvas2D Context

WebGL interface support:

Supports the properties, methods, and constants defined by WebGL 1.0 and WebGL 2.0. Supported extensions are listed in the table below.
