AddEllipseAnnot Method (AnnotationManager)

In This Topic

Adds a new GdPicture/XMP ellipse annotation on the selected page of the document currently handled by this AnnotationManager object according to the parameters you have specified. This annotation represents a filled and bordered ellipse or circle drawn with the specified colors.

The type of the newly added annotation object is GdPictureAnnotationType.AnnotationTypeEllipse. You can change the annotation properties directly using the GdPicture14.Annotations.AnnotationEllipse 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 AddEllipseAnnot( _
   ByVal BorderColor As Color, _
   ByVal Left As Single, _
   ByVal Top As Single, _
   ByVal Width As Single, _
   ByVal Height As Single _
) As AnnotationEllipse

public AnnotationEllipse AddEllipseAnnot( 
   Color BorderColor,
   float Left,
   float Top,
   float Width,
   float Height
)

public function AddEllipseAnnot( 
    BorderColor: Color;
    Left: Single;
    Top: Single;
    Width: Single;
    Height: Single
): AnnotationEllipse;

public function AddEllipseAnnot( 
   BorderColor : Color,
   Left : float,
   Top : float,
   Width : float,
   Height : float
) : AnnotationEllipse;

public: AnnotationEllipse* AddEllipseAnnot( 
   Color BorderColor,
   float Left,
   float Top,
   float Width,
   float Height
)

public:
AnnotationEllipse^ AddEllipseAnnot( 
   Color BorderColor,
   float Left,
   float Top,
   float Width,
   float Height
)

Parameters

BorderColor: A color object that defines the required border color of the newly added ellipse annotation.
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 AnnotationEllipse object. The newly added GdPicture/XMP ellipse 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.
