如何在视图剪切路径上设置大小

Question

我正在尝试使用路径几何和svg路径剪切pancakeview对象。但是我无法控制形状的大小。路径具有纵横比，这是路径的解决方案，但我需要纵横比或类似的东西来控制剪辑大小。

            <yummy:PancakeView HorizontalOptions="FillAndExpand" BorderGradientAngle="45" VerticalOptions="FillAndExpand">
                <yummy:PancakeView.Clip>
                    <PathGeometry Figures="M285.257,35.528c58.743,0.286,106.294,47.836,106.58,106.58
