backLayer.graphics.clear();
	backLayer.graphics.beginBitmapFill(bitmapData);
	backLayer.graphics.drawTriangles(vertices, indices, uvtData);

var bitmapData = new LBitmapData(null, 0, 0, 480, 480);
        bitmapData.draw(backLayer);

用backLayer.graphics画一个透明的矩形就可以了

backLayer.graphics.clear();
backLayer.graphics.drawRect(0,"#000000",[0, 0, 354,600],false,"#000000");
backLayer.graphics.beginBitmapFill(bitmapData);
backLayer.graphics.drawTriangles(vertices, indices, uvtData);

var bitmapData = new LBitmapData(null, 0, 0, 480, 480);
        bitmapData.draw(backLayer);

画一个透明的矩形后，再绘制这个图层，会出现二张图片。

backLayer.graphics.clear();
backLayer.graphics.drawRect(0,"#000000",[0, 0, 354,600],false,"#000000 ...

试试这样呢

1. backLayer.graphics.clear();
   
2. backLayer.graphics.beginBitmapFill(bitmapData);
   
3. backLayer.graphics.drawTriangles(vertices, indices, uvtData);
   
4. 
   
5. var rectLayer = new LSprite();
   
6. rectLayer.graphics.drawRect(0,"#000000",[0, 0, 354,600],false,"#000000");
   
7. backLayer.addChild(rectLayer);
