Public Function GetExtraPenWidth ( _

public double GetExtraPenWidth(

public function GetExtraPenWidth(

Parameters
- geometryHost
Type: Microsoft.VisualStudio.Modeling.Diagrams.IGeometryHost
The shape or link.
Return Value
Type: System.Double
The portion of the pen width that draws outside the borders of the geometry.
Remarks
When the outline of a shape is drawn, the pen follows a path along the boundary of the shape. The pen has a finite thickness. Therefore part of the painted boundary will be outside the actual boundary of the shape. This function returns the portion of the pen – usually half the pen width – that is outside the boundary. This information is required when computing the area that must be repainted when the shape is invalidated.
