GetAnnotationFillColor Method (GdPicturePDF)

In This Topic
Returns 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
'Declaration

 

Public Function GetAnnotationFillColor( _

   ByVal AnnotationIdx As Integer _

) As Color
public Color GetAnnotationFillColor( 

   int AnnotationIdx

)
public function GetAnnotationFillColor( 

    AnnotationIdx: Integer

): Color; 
public function GetAnnotationFillColor( 

   AnnotationIdx : int

) : Color;
public: Color GetAnnotationFillColor( 

   int AnnotationIdx

) 
public:

Color GetAnnotationFillColor( 

   int AnnotationIdx

) 

Parameters

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

Return Value

The interior color of the specified annotation object. The GetStat method can be subsequently used to determine if this method has been successful.
Remarks
This method is only allowed for use with non-encrypted documents.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.

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

Just to inform you, that this parameter is only meaningful to use for specific annotation types described in the Summary section above.
