GetAnnotationType Method (AnnotationManager)

In This Topic

Returns the type of a required GdPicture/XMP annotation object specified by its index related to the selected page of the document currently handled by this AnnotationManager object.

Be aware that this method only handles GdPicture/XMP annotations. Likewise, annotations are always treated relative to the selected page.

'Declaration
 
Public Function GetAnnotationType( _
   ByVal AnnotationIdx As Integer _
) As Annotation.GdPictureAnnotationType

public Annotation.GdPictureAnnotationType GetAnnotationType( 
   int AnnotationIdx
)

public function GetAnnotationType( 
    AnnotationIdx: Integer
): Annotation.GdPictureAnnotationType;

public function GetAnnotationType( 
   AnnotationIdx : int
) : Annotation.GdPictureAnnotationType;

public: Annotation.GdPictureAnnotationType GetAnnotationType( 
   int AnnotationIdx
)

public:
Annotation.GdPictureAnnotationType GetAnnotationType( 
   int AnnotationIdx
)

Parameters

AnnotationIdx: The 0-based index of the required annotation within the selected page of the handled document. It must be a value from 0 to AnnotationManager.GetAnnotationCount-1.

Return Value

A member of the GdPictureAnnotationType enumeration. The AnnotationManager.GetStat method can be subsequently used to determine if this method has been successful.

Remarks

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

Please ensure that you have selected the proper page before starting any annotation related action with the handled document. Annotations are always treated relative to the currently selected page.
