GetAnnotationType Method (GdPicturePDF)

In This Topic
Returns the type of a required annotation object specified by its index related to the currently selected page of the loaded PDF document. It is always "Annot" for properly defined annotation object. Please use the GetAnnotationSubType method to find out the specific subtype of the required annotation object, as it is shown in the example below.
Syntax
'Declaration

 


Public Function GetAnnotationType( _

   ByVal AnnotationIdx As Integer _

) As String
public string GetAnnotationType( 

   int AnnotationIdx

)
public function GetAnnotationType( 

    AnnotationIdx: Integer

): String; 
public function GetAnnotationType( 

   AnnotationIdx : int

) : String;
public: string* GetAnnotationType( 

   int AnnotationIdx

) 
public:

String^ GetAnnotationType( 

   int AnnotationIdx

)

Parameters

AnnotationIdx
The 0-based index of the required annotation within the current page. It must be a value from 0 to GetAnnotationCount-1.

Return Value

The type of the specified annotation object, if defined properly, must be "Annot". Specifically, the correct return value should be always "Annot". The GetStat method can be subsequently used to determine if this method has been successful.
Remarks
This method is only allowed for use with non-encrypted documents.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.

Please always ensure that you have selected the correct page using the SelectPage method before applying an annotation index.

Just to remind you, that you need to use the GetAnnotationSubType method to find out the specific subtype of the required annotation object, as it is shown in the example below.
