Sets the interior color of a required annotation object specified by its index related to the currently selected page of the loaded PDF document.

This color is used for the following purposes:

To specify the interior color with which to fill the annotation’s rectangle or ellipse (for Square or Circle annotation types).
To specify the interior color with which to fill the annotation’s line endings (for Line, Polygon or PolyLine annotation types).

Syntax

public GdPictureStatus SetAnnotationFillColor( 
   int AnnotationIdx,
   GdPictureColor Color
)

public function SetAnnotationFillColor( 
    AnnotationIdx: Integer;
    Color: GdPictureColor
): GdPictureStatus;

public function SetAnnotationFillColor( 
   AnnotationIdx : int,
   Color : GdPictureColor
) : GdPictureStatus;

public: GdPictureStatus SetAnnotationFillColor( 
   int AnnotationIdx,
   GdPictureColor Color
)

public:
GdPictureStatus SetAnnotationFillColor( 
   int AnnotationIdx,
   GdPictureColor Color
)

'Declaration
 
Public Overloads Function SetAnnotationFillColor( _
   ByVal AnnotationIdx As Integer, _
   ByVal Color As GdPictureColor _
) As GdPictureStatus

Parameters

AnnotationIdx: The 0-based index of the required annotation within the current page. It must be a value from 0 to GdPicturePDF.GetAnnotationCount-1.
Color: The annotation intertior color.

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

This method is only allowed for use with non-encrypted documents.

Likewise always ensure that you have selected the correct page using the GdPicturePDF.SelectPage method before applying an annotation index.
