  • Reference

Definition

Namespace:
System.Windows.Media
Assembly:
PresentationCore.dll

Gets or sets the limit on the ratio of the miter length to half this pen's Thickness.

public:
 property double MiterLimit { double get(); void set(double value); };
public double MiterLimit { get; set; }
member this.MiterLimit : double with get, set
Public Property MiterLimit As Double

Property Value

Double

The limit on the ratio of the miter length to half the pen's Thickness. This value is always a positive number greater than or equal to 1. The default value is 10.0.

Examples

The following example shows how to use the MiterLimit property to limit the size of a corner created by two line segments.

                <!-- The MiterLimit is set to a value of 0 so the corner formed
                     by where the two line segments join is cut or blunted. A larger 
                     value would allow for the corner to extend out even beyond 
                     the thickness of the line. -->

The following illustration shows what this code example produces.

Shows MiterLimit example. Corner formed is cut.

Remarks

A miter is a joint made by beveling each of two surfaces to be joined to form a corner. When two line segments meet at a sharp angle, the miter may extend beyond the thickness of the line that strokes the path.
