The GeometryCombineMode property specifies how the two geometries will be combined. Note that CombinedGeometry combines the area specified by two geometries, so geometries that do not have area (such as LineGeometry) disappear when combined.
Geometries can be combined in several ways: using a GeometryGroup, a CombinedGeometry, or the Combine method of the Geometry class.
A GeometryGroup creates a composite geometry from one or more Geometry objects.
A CombinedGeometry uses a specified boolean operation to combine the area described by two Geometry objects.
The static Combine method of the Geometry class behaves in exactly the same manner as the CombinedGeometry object.
Careful thought should be involved when using a CombinedGeometry to perform a union as it can be very CPU-expensive. In most cases, a GeometryGroup or AddGeometry will work better.
Use a CombinedGeometry only when any of the following apply:
The geometric operation is not a union.
Either of the geometries have a FillRule value of EvenOdd and the geometries are self-intersecting (i.e. the FillRule actually matters).
Time is not a concern, but space is (for instance, if the geometry is created once and then cached). Typically, CombinedGeometry produces smaller output than AddGeometry.
The resulting geometry will be stroked or used in a path animation and AddGeometry does not provide the desired outline.
A CombinedGeometry is a type of Freezable object. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.
