This class is a replacement for the deprecated shadow property of the DisplayObject class. Please consider to use the DropShadowFilter class which is the recommended technique to render shadows in WebGL.

The CanvasShadowWrapper takes an arbitrary DisplayObject and renders it with a drop shadow if the render engine is Canvas2D (not WebGL).

Example with deprecated shadow property:

var spaceship = new Spaceship();
spaceship.x = 160;
spaceship.y = 200;
spaceship.shadow = new Shadow(Color.Black, 10, 10, 5);
stage.addChild(spaceship);

Example with the CanvasShadowWrapper class:

var spaceship = new Spaceship();
spaceship.x = 160;
spaceship.y = 200;
var shadow = new CanvasShadowWrapper(spaceship, Color.Black, 10, 10, 5);
stage.addChild(shadow);
