How to: Create a Combined Geometry
This example shows how to combine geometries. To combine two geometries, use a xref:System.Windows.Media.CombinedGeometry object. Set its xref:System.Windows.Media.CombinedGeometry.Geometry1%2A and xref:System.Windows.Media.CombinedGeometry.Geometry2%2A properties with the two geometries to combine, and set the xref:System.Windows.Media.CombinedGeometry.GeometryCombineMode%2A property, which determines how the geometries will be combined together, to Union, Intersect, Exclude, or Xor.
To create a composite geometry from two or more geometries, use a xref:System.Windows.Media.GeometryGroup.
Example
In the following example, a xref:System.Windows.Media.CombinedGeometry is defined with a geometry combine mode of Exclude. Both xref:System.Windows.Media.CombinedGeometry.Geometry1%2A and the xref:System.Windows.Media.CombinedGeometry.Geometry2%2A are defined as circles of the same radius, but with centers offset by 50.

Combined Geometry Exclude
In the following markup, a xref:System.Windows.Media.CombinedGeometry is defined with a combine mode of Intersect. Both xref:System.Windows.Media.CombinedGeometry.Geometry1%2A and the xref:System.Windows.Media.CombinedGeometry.Geometry2%2A are defined as circles of the same radius, but with centers offset by 50.
[!code-xamlGeometrySample#22]
Combined Geometry Intersect
In the following markup, a xref:System.Windows.Media.CombinedGeometry is defined with a combine mode of Union. Both xref:System.Windows.Media.CombinedGeometry.Geometry1%2A and the xref:System.Windows.Media.CombinedGeometry.Geometry2%2A are defined as circles of the same radius, but with centers offset by 50.

Combined Geometry Union
In the following markup, a xref:System.Windows.Media.CombinedGeometry is defined with a combine mode of Xor. Both xref:System.Windows.Media.CombinedGeometry.Geometry1%2A and the xref:System.Windows.Media.CombinedGeometry.Geometry2%2A are defined as circles of the same radius, but with centers offset by 50.
