GetAnnotationXML Method (AnnotationManager)

In This Topic

Saves the annotation data of the required GdPicture/XMP annotation object, that is specified by its index related to the selected page of the handled document, to an XML formatted string. You can subsequently use the AddAnnotationFromXML method to add the exactly same annotation wherever you need.

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

'Declaration
 
Public Function GetAnnotationXML( _
   ByVal AnnotationIdx As Integer _
) As String

public string GetAnnotationXML( 
   int AnnotationIdx
)

public function GetAnnotationXML( 
    AnnotationIdx: Integer
): String;

public function GetAnnotationXML( 
   AnnotationIdx : int
) : String;

public: string* GetAnnotationXML( 
   int AnnotationIdx
)

public:
String^ GetAnnotationXML( 
   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 GetAnnotationCount-1.

Return Value

A string containing the annotation definition in XML format. The GetStat method can be subsequently used to determine if this method has been successful.

Remarks

It is recommend to use the 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.
