C# WPF: Geometric Operations

Question

I know WPF supports some geometric operations, but I'm wondering if it supports others.

I know it supports:

• The bounding box of a polygon/path or collection of a polygons/paths.
• Determine whether a given polygon/path lies within another polygon/path.

Does it support:

• Unions
• Intersections
• The ability to determine if two shapes share a common border

Answer 1

To create a union or intersection of two geometries, use a CombinedGeometry and set the GeometryCombineMode to Union or Intersect.

If you're just trying to find out if two geometries intersect, look at StrokeContainsWithDetail and FillContainsWithDetail.
