Combine multiple Ellipses
I need a way to combine multiple EllipseGeometry to make a union between them, but CombineGeometry class only can combine 2 Geometries. The ideal way is 开发者_JS百科to have a class similar CombineGeometry that accepts more than Geometry1 and Geometry2 shapes.
Anyone knows an object that makes such a behaviour?EllipseGeometry is a Geometry too so you can combine like this:
<CombinedGeometry GeometryCombineMode="Union">
<CombinedGeometry.Geometry1>
<EllipseGeometry RadiusX="70" RadiusY="30" Center="100,150" />
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<EllipseGeometry RadiusX="70" RadiusY="30" Center="200,150" />
</CombinedGeometry.Geometry2>
</CombinedGeometry>
EDIT To combine three or more EllipseGeometries you could use this mechanism
<CombinedGeometry GeometryCombineMode="Union">
<CombinedGeometry.Geometry1>
<CombinedGeometry GeometryCombineMode="Union">
<CombinedGeometry.Geometry1>
<EllipseGeometry RadiusX="70" RadiusY="30" Center="100,150" />
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<EllipseGeometry RadiusX="70" RadiusY="30" Center="200,150" />
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<EllipseGeometry RadiusX="70" RadiusY="30" Center="100,150" />
</CombinedGeometry.Geometry2>
</CombinedGeometry>
You can create a new class that is derived from Geometry and have a Geometry[] in it and implement methods using above mechanism.
