    ) 
    public:
    double GetRegionBorderWidth( 
       int RegionID
    ) 

    Parameters

    RegionID
    A unique region identifier of the specified region. You can obtain this identifier using the GetRegionID method or when creating regions using the AddRegion(String,Double,Double,Double,Double,Color,RegionFillMode) method.

    Return Value

    The border width, in inches, of the specified region. Please always use the GetStat method to determine if this method has been successful.
