GetRegionColorSelection Method (GdViewer)

In This Topic

Gets the fill color of a highlighted region, when it is selected by the user. The region is 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 this color of each highlighted region using the SetRegionColorSelection(Int32,Color) method.

'Declaration

 

Public Function GetRegionColorSelection( _

   ByVal RegionID As Integer _

) As Color

public Color GetRegionColorSelection( 

   int RegionID

)

public function GetRegionColorSelection( 

    RegionID: Integer

): Color;

public function GetRegionColorSelection( 

   RegionID : int

) : Color;

public: Color GetRegionColorSelection( 

   int RegionID

)

public:

Color GetRegionColorSelection( 

   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 AddRegion(String,Int32,Int32,Int32,Int32,ForegroundMixMode,Int32) or AddRegionInches(String,Single,Single,Single,Single,ForegroundMixMode,Int32) methods.

Return Value

The fill color of the specified region when it is selected by the user. 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 fill color set by the toolkit is aquamarine, ARGB(127, 255, 212).
