SetRegionBorderWidth Method (GdViewer)

In This Topic

Sets 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 determine the border width of each highlighted region using the GetRegionBorderWidth method.

'Declaration

 

Public Function SetRegionBorderWidth( _

   ByVal RegionID As Integer, _

   ByVal BorderWidth As Integer _

) As GdPictureStatus

public GdPictureStatus SetRegionBorderWidth( 

   int RegionID,

   int BorderWidth

)

public function SetRegionBorderWidth( 

    RegionID: Integer;

    BorderWidth: Integer

): GdPictureStatus;

public function SetRegionBorderWidth( 

   RegionID : int,

   BorderWidth : int

) : GdPictureStatus;

public: GdPictureStatus SetRegionBorderWidth( 

   int RegionID,

   int BorderWidth

)

public:

GdPictureStatus SetRegionBorderWidth( 

   int RegionID,

   int BorderWidth

)

Parameters

RegionID: A unique region identifier of the specified region. You can obtain this identifier using the GetRegionID method or when creating regions using AddRegion(String,Int32,Int32,Int32,Int32,ForegroundMixMode,Int32) or AddRegionInches(String,Single,Single,Single,Single,ForegroundMixMode,Int32) methods.
BorderWidth: The new border width, in inches, of the specified region.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.

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.
