InitFromGdPictureImage Method (AnnotationManager)
Initializes the current AnnotationManager object from a required GdPictureImage object identified by an unique image identifier. 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 image.
'Declaration
Public Function InitFromGdPictureImage( _
ByVal As Integer _
) As GdPictureStatus
Parameters
- ImageID
- A unique image identifier of the GdPictureImage object representing the required image. You can obtain this identifier, for example, using methods of the GdPictureImaging class when creating the image resource.
Be aware that 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.
