Close() Method

In This Topic
Closes the current AnnotationManager object by releasing the loaded document and all related annotations data. It is a good practice to call this method when you complete all the necessary annotation handling of the document.
Syntax
'Declaration

 


Public Function Close() As GdPictureStatus
public GdPictureStatus Close()
public function Close(): GdPictureStatus; 
public function Close() : GdPictureStatus;
public: GdPictureStatus Close(); 
public:

GdPictureStatus Close();

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 neither document nor annotations are associated with this AnnotationManager object after closing it anymore.
