Geometry.GetWidenedPathGeometry Method (Pen, Double, ToleranceType)

 

Gets a PathGeometry that is the shape defined by the stroke on the Geometry produced by the specified Pen, given the specified tolerance factor.

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

Public Overridable Function GetWidenedPathGeometry (
	pen As Pen,
	tolerance As Double,
	type As ToleranceType
) As PathGeometry

Parameters

pen
Type: System.Windows.Media.Pen

The object used to define the area of the geometry's stroke.

tolerance
Type: System.Double

The maximum bounds on the distance between points in the polygonal approximation of the geometry. Smaller values produce more accurate results but cause slower execution. If tolerance is less than .000001, .000001 is used instead.

type
Type: System.Windows.Media.ToleranceType

One of the ToleranceType values that specifies whether the tolerance factor is an absolute value or relative to the area of the geometry.

Return Value

Type: System.Windows.Media.PathGeometry

The geometry, widened by pen.

Some Geometry methods (such as GetWidenedPathGeometry) 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.
