member this.GetBoundingRectangles : unit -> System.Windows.Rect[]
Public Function GetBoundingRectangles () As Rect()
Returns
An array of bounding rectangles for each full or partial line of text in a text range.
An empty array for a degenerate text range.
An empty array for a text range that has screen coordinates placing it completely off-screen, scrolled out of view, or obscured by an overlapping window.
