InitFromGdPicturePDF Method (AnnotationManager)

In This Topic
Initializes the current AnnotationManager object from a PDF document handled by a specified GdPicturePDF object. The document previously handled by this AnnotationManager object will automatically close.

Be aware that the AnnotationManager object only handles GdPicture/XMP annotations contained in the source PDF document.

Syntax
'Declaration
 

Public Function InitFromGdPicturePDF( _
   ByVal PDF As GdPicturePDF _
) As GdPictureStatus
public GdPictureStatus InitFromGdPicturePDF( 
   GdPicturePDF PDF
)
public function InitFromGdPicturePDF( 
    PDF: GdPicturePDF
): GdPictureStatus; 
public function InitFromGdPicturePDF( 
   PDF : GdPicturePDF
) : GdPictureStatus;
public: GdPictureStatus InitFromGdPicturePDF( 
   GdPicturePDF* PDF
) 
public:
GdPictureStatus InitFromGdPicturePDF( 
   GdPicturePDF^ PDF
)

Parameters

PDF
The GdPicturePDF object that handles a required PDF document. This object must be properly initialized before it can be sent into this method and it must be disposed of by the user as well.

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 requires the Annotations component to run.

How to initialize the AnnotationManager object from already initialized GdPicturePDF object.
