Parameters
- geometryHost
Type: Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost
The instance data for the geometry.
- hitPoint
Type: Microsoft.VisualStudio.Modeling.Diagrams.PointD
The point to test. The point is in world units and is relative to the top-left of the IGeometryHost's parent.
- hitTestInfo
Type: Microsoft.VisualStudio.Modeling.Diagrams.DiagramHitTestInfo
The object which will be updated with the hit test results. This argument may be null in which case it is ignored.
- includeTolerance
Type: System.Boolean
true to include tolerance in the HitTest calculation; false to exclude tolerance.
Return Value
Type: System.Boolean
Remarks
The geometry boundary includes the thickness of the outline pen that lies outside of the graphics path used to draw the geometry.
