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.

• includeTolerance
  Type: Boolean

  true to include tolerance in the HitTest calculation; false to exclude tolerance.

Return Value

Type: Boolean

Remarks

The geometry boundary includes the thickness of the outline pen that lies outside of the graphics path used to draw the geometry.
