     //居中对齐
     bitmap.x = (s.stage.desWidth - bitmap.width) / 2;
     bitmap.y = (s.stage.desHeight - bitmap.height) / 2;
     s.addChild(bitmap);
     //截取图片的某一部分显示
     var rect = new annie.Rectangle(0, 0, 200, 200),
     rectBitmap = new annie.Bitmap(imgEle, rect);
     rectBitmap.x = (s.stage.desWidth - bitmap.width) / 2;
     rectBitmap.y = 100;
