AddTextAnnot Method (AnnotationManager)

In This Topic

Adds a new GdPicture/XMP text annotation on the selected page of the document currently handled by this AnnotationManager object according to the parameters you have specified. A text annotation writes the specified text within the defined rectangle area.

The type of the newly added annotation object is GdPictureAnnotationType.AnnotationTypeText. You can change the annotation properties directly using the GdPicture14.Annotations.AnnotationText class right after the successful creation of the annotation object.

Be aware that annotations are always treated relative to the currently selected page.

'Declaration
 
Public Function AddTextAnnot( _
   ByVal Left As Single, _
   ByVal Top As Single, _
   ByVal Width As Single, _
   ByVal Height As Single, _
   ByVal Text As String _
) As AnnotationText

public AnnotationText AddTextAnnot( 
   float Left,
   float Top,
   float Width,
   float Height,
   string Text
)

public function AddTextAnnot( 
    Left: Single;
    Top: Single;
    Width: Single;
    Height: Single;
    Text: String
): AnnotationText;

public function AddTextAnnot( 
   Left : float,
   Top : float,
   Width : float,
   Height : float,
   Text : String
) : AnnotationText;

public: AnnotationText* AddTextAnnot( 
   float Left,
   float Top,
   float Width,
   float Height,
   string* Text
)

public:
AnnotationText^ AddTextAnnot( 
   float Left,
   float Top,
   float Width,
   float Height,
   String^ Text
)

Parameters

Left: The horizontal (X) coordinate of the top left point, in inches, where the annotation bounding box is to be located.
Top: The vertical (Y) coordinate of the top left point, in inches, where the annotation bounding box is to be located.
Width: The width of the annotation bounding box, in inches.
Height: The height of the annotation bounding box, in inches.
Text: The content of the newly added annotation, that means the text to be displayed in the annotation bounding box.

Return Value

A GdPicture/XMP AnnotationText object. The newly added GdPicture/XMP text annotation.

Remarks

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.

You can regularly apply the AnnotationManager.GetStat method to determine if this method has been successful.
