给你

<Path Width="100" Fill="#4F81BD" Stretch="uniform" Stroke="#385D8A" StrokeThickness="3" Data="M 100,119 C 102,109 107,101 120,100 L 220,100 C 231,101 241,110 240,120 L 241,159 C 241,170 230,180 220,180 L 120,180 C 111,180 100,171 100,160 L 100.5,139.5 L 70,120 Z"/>

可根据使用情况进行调整

你可以使用它作为背景刷，绘制图像，几何图形，甚至不透明度蒙版，如果你寻找特殊效果。
