The StartingElement is the address corresponding to the inner top left corner of the top left Cell in the CellRange.
The EndingElement is the address corresponding to the outer top left corner of the bottom right Cell in the CellRange.
For example, if the range determined by the addresses "A2 : E5", the Picture starts at the inner top left corner of the A2 Cell and pass through it until it reaches the outer corner of the E5 Cell, which it will only touch and not pass through.
Note that the StartingElement and EndingElement can also have the same value. In that case, a OneCellAnchor will be created.
Also note that setting a value in this property will remove the value in the AbsolutePosition property because an anchor using the AbsolutePosition property is an AbsoluteAnchor, which doesn't use the AnchorPosition property.
