Geometry.GetRenderBounds Method (Pen, Double, ToleranceType)

Returns an axis-aligned rectangle that is exactly large enough to contain the geometry after it has been outlined with the specified Pen, given the specified tolerance factor.

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

public virtual Rect GetRenderBounds(
	Pen pen,
	double tolerance,
	ToleranceType type
)

Parameters

pen
Type: System.Windows.Media.Pen
An object that describes 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.Rect
An axis aligned rectangle that is exactly large enough to contain the outlined geometry.

Some Geometry methods (such as GetRenderBounds) 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.
