[]舞台上有个label，我能通过截图保存成图片么

Laya.init(800, 800);

			Laya.stage.bgColor = "#eeffcc";

			Laya.stage.alignH = Stage.ALIGN_CENTER;

			Laya.stage.alignV = Stage.ALIGN_MIDDLE;

			

			var sp:Sprite=new Sprite();

			

			sp.graphics.drawRect(0,0,200,200,"#EEFF00");

			

			var label:Label=new Label();

			label.fontSize=60;

			label.text="666";

			label.bold=true;

			label.color="#000000";

			sp.addChild(label);

			sp.size(200,200);

			

			Laya.stage.addChild(sp);

			

			Laya.timer.frameLoop(60,this,function():void{

				var htmlC:HTMLCanvas=sp.drawToCanvas(200,200,0,0);

				var texture:Texture=new Texture(htmlC);

				

				var sp2:Sprite=new Sprite();

				sp2.graphics.drawTexture(texture,100,100,100,100);

				sp2.pos(300,0);

				Laya.stage.addChild(sp2);
