AddCommentAnnot Method (AnnotationManager)

In This Topic

Adds and attaches a new GdPicture/XMP comment annotation to already existing annotation located on the selected page of the document currently handled by this AnnotationManager object according to the parameters you have specified. A comment annotation enables users to share information (comments, answers, reviews) related to the connected annotation.

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

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

   float Width,
   float Height
)

public function AddCommentAnnot( 
    PreviousGuid: String;

): AnnotationComment;

public function AddCommentAnnot(

   Width : float,
   Height : float
) : AnnotationComment;

public: AnnotationComment* AddCommentAnnot( 
   string* PreviousGuid,
   float Left,
   float Top,
   float Width,
   float Height
)

public:
AnnotationComment^ AddCommentAnnot( 
   String^ PreviousGuid,
   float Left,
   float Top,
   float Width,
   float Height
)

Parameters

PreviousGuid: The unique identifier of the existing annotation object to which the new comment is related.
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.

Return Value

A GdPicture/XMP AnnotationComment object. The newly added GdPicture/XMP comment 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 GetStat method to determine if this method has been successful.
