请问一下，怎么将下面这段AS3代码翻译成LayaAir的API

silverys

我想把一个以前AS3写的翻页效果移植过来。我发现LayaAir没有BitmapData的draw方法

var sprite_:Sprite = new Sprite();
var bitmap_:BitmapData = new BitmapData(_loader.width, _loader.height);
bitmap_.draw(_loader, new Matrix());
var matrix:Matrix = new Matrix();
matrix.rotate(Math.PI/4);
sprite_.graphics.beginBitmapFill(bitmap_, matrix, true);
sprite_.graphics.drawRect(100, 50, 200, 90);
sprite_.graphics.endFill();
addChild(sprite_);

package 
{
	import laya.display.Sprite;
	import laya.maths.Matrix;
	import laya.net.Loader;
	import laya.resource.Texture;
	import laya.utils.Handler;

	public class LayaAirDemo
	{
		public function LayaAirDemo()
		{
			Laya.init(700,600);
			Laya.loader.load('res/apes/monkey2.png',Handler.create(this,onLoaded))
		}
		
		private function onLoaded():void
		{
			var texture:Texture=Loader.getRes('res/apes/monkey2.png');
			var sp:Sprite=new Sprite();
			var matrix:Matrix=new Matrix();
			matrix.rotate(Math.PI/4);
			matrix.translate(150,100);
			sp.graphics.drawTexture(texture,0,0,texture.width,texture.height,matrix);
			sp.graphics.drawRect(100,50,200,90,'#000000');
			Laya.stage.addChild(sp);
		}
	}
