TextElement edges are not considered content for the purposes of this method. If the TextPointer is positioned before a TextElement edge, the return value is a bounding box for the next non-TextElement content in the specified direction. If there is no content in the specified direction, a zero-width Rect is returned with a height matching the height of any preceding content.
The operation performed by this method depends on a valid layout. When necessary, this method attempts to automatically regenerate a valid layout before proceeding with the operation. Regenerating a layout can be a relatively expensive operation. Use the HasValidLayout property to check for a valid layout before performing operations that may regenerate the layout. For more information, see Layout System.
