LoadAnnotationsFromXMP(String) Method

Syntax
Remarks
Example
See Also

Loads the GdPicture/XMP annotations from a specified XML formatted file, that has been previously generated using the GdViewer.SaveAnnotationsToXMP method or the GdViewer.SaveAnnotationsToXMPEx method. The loaded annotations are subsequently applied to the document currently displayed in the GdViewer control to the current page or all pages, respectively. This means that the loaded annotations will replace the current annotations presented in the document.

Be aware that this method only handles GdPicture/XMP annotations.

   string FilePath

public function LoadAnnotationsFromXMP( 
    FilePath: String

public function LoadAnnotationsFromXMP( 
   FilePath : String
) : GdPictureStatus;

public: GdPictureStatus LoadAnnotationsFromXMP( 
   string* FilePath
)

public:
GdPictureStatus LoadAnnotationsFromXMP( 
   String^ FilePath
)

'Declaration
 
Public Overloads Function LoadAnnotationsFromXMP( _
   ByVal FilePath As String _
) As GdPictureStatus

Parameters

FilePath: The file path of the properly formatted XML file to load.

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

The method only handles GdPicture/XMP annotations as well.

Be aware that the loaded annotations will replace the current annotations presented in the document. For adding new annotations you can use the AnnotationManager.AddAnnotationFromXML method.

    Dim pageNr As Integer = GdViewer1.CurrentPage
    GdViewer1.CloseDocument()
    If (GdViewer1.DisplayFromFile("test.pdf") = GdPictureStatus.OK) AndAlso
       (GdViewer1.LoadAnnotationsFromXMP("annots.xml") = GdPictureStatus.OK) Then
