    local clipSize = mask:getContentSize()
    dump(clipSize)

    clippingNode:setContentSize(clipSize) --设置尺寸大小
    clippingNode:setStencil(mask)  --设置模板stencil
    clippingNode:setAlphaThreshold(0.05) --设置alpha闸值
    --

    --clippingNode:addChild(redPackage, 1)  --先添加标题,会完全显示出来,因为跟模板一样大小
    clippingNode:addChild(im,2)       --会被裁减

    scene:addChild(clippingNode,9999)
