我有這個橢圓:橢圓與CombinedGeometry
<Ellipse Name="backgroundEllipse1" Fill="Pink">
<Ellipse.Clip>
<CombinedGeometry GeometryCombineMode="Exclude">
<CombinedGeometry.Geometry1>
<EllipseGeometry x:Name="backgroundEllipseMask1" Center="150,150" RadiusX="300" RadiusY="300"></EllipseGeometry>
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<EllipseGeometry x:Name="backgroundEllipseMask2" Center="150,150" RadiusX="130" RadiusY="130"></EllipseGeometry>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</Ellipse.Clip>
</Ellipse>
我想結合中心和半徑值,但有些東西逃脫了我。
