GetRegionBorderWidth Method (GdViewer)

In This Topic

Gets the border width, in inches, of a highlighted region specified by its unique identifier related to the document currently displayed in the GdViewer control. These regions, if present, determines the currently defined highlighted regions on the displayed document.

You can define the border width of each highlighted region using the SetRegionBorderWidth method.

'Declaration

 

Public Function GetRegionBorderWidth( _

   ByVal RegionID As Integer _

) As Double

public double GetRegionBorderWidth( 

   int RegionID

)

public function GetRegionBorderWidth( 

    RegionID: Integer

): Double;

public function GetRegionBorderWidth( 

   RegionID : int

) : double;

public: double GetRegionBorderWidth( 

   int RegionID

)

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. The GetStat method can be subsequently used to determine if this method has been successful.

Remarks

Be aware that if the required region does not exist, the method will fail.

Just to inform you, that the default border width set by the toolkit is 0.
