IntersectionDetail Enumeration


Provides information about the intersection between the geometries in the GeometryHitTestParameters and the visual which was hit.

Namespace:   System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public enum IntersectionDetail

Member nameDescription

The Geometry hit test parameter and the target visual, or geometry, do not intersect.


The Geometry hit test parameter is fully contained within the boundary of the target visual or geometry.


The target visual, or geometry, is fully inside the Geometry hit test parameter.


The Geometry hit test parameter and the target visual, or geometry, intersect. This means that the two elements overlap, but neither element contains the other.


The IntersectionDetail value is not calculated.

The following illustration shows the relationship between the hit test geometry (the blue circle) and the visual geometry (the red square).
