Geometry.StrokeContains Method (Pen, Point, Double, ToleranceType)

Determines whether the specified Point is contained in the stroke produced by applying the specified Pen to this geometry, given the specified margin of error.

) : boolean
You cannot use methods in XAML.



An object that defines the stroke of a geometry.


The point to test for containment.


The maximum bounds on the distance between points in the polygonal approximation of this geometry. Smaller values produce more accurate results but cause slower execution. If tolerance is less than 10-6, 10-6 is used instead.


One of the enumeration values, Absolute or Relative, that specifies whether the tolerance factor is an absolute value or relative to the area of the geometry's stroke.

Return Value

true if the stroke created by applying the specified Pen to this geometry contains the specified point, given the specified tolerance factor; otherwise, false.

Some Geometry methods (such as StrokeContains) produce or use a polygonal approximation of the geometry. The tolerance factor specifies the maximum distance between points in this polygonal approximation. Smaller tolerance values produce better approximations, but require more processing than an approximation with a large tolerance factor.
