鏡面反射

ActionScript 3.0による鏡面反射の実装です。

sample.as

var urlReq:URLRequest = new URLRequest("AutumnLeaves.jpg");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);
loader.load(urlReq);
function completeHandler(e:Event):void {
        var gmask:Sprite = new Sprite();
        var bmpSprite:Sprite= new Sprite();
        var _bmpSprite:Sprite= new Sprite();
        var _bmp:Bitmap = Bitmap(loader.content);
        _bmp.scaleY=-1.0;
        _bmp.y=_bmp.height*2;
        var fillType:String = GradientType.LINEAR;
        var colors:Array = [0x000000, 0x000000];
        var alphas:Array = [0.4, 1];
        var ratios:Array = [0, 255];
        var matrix:Matrix = new Matrix();
        matrix.createGradientBox(_bmp.height,_bmp.width,Math.PI/2,_bmp.width);
        gmask.graphics.beginGradientFill(fillType, colors, alphas, ratios, matrix);
        gmask.graphics.drawRect(0,0,_bmp.width,_bmp.height);
        gmask.y = _bmp.height;
        _bmpSprite.addChild(_bmp);
        _bmpSprite.addChild(gmask);
        addChild(_bmpSprite);
