import maskSlider.MaskSlider;

var slider:MaskSlider = new MaskSlider(new Dragger());

slider.x = 10;
slider.y = 10;



var colorPic:DisplayObject = new ColorPic();
var bwPic:DisplayObject = new BwPic();


slider.initialize(colorPic, bwPic, 0.5);
addChild(slider);


var req:URLRequest = new URLRequest("http://folk.uio.no/susankna/bilder/bilde1.jpg");
var loader:Loader = new Loader();

addChild(loader);
loader.load(req);
