This position is determined by a StartingElement & an EndingElement, which sets a CellRange.
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 is determined by the addresses "A2 : E5", the Picture will start at the inner top left corner of the A2 Cell & pass through it until it reaches the outer corner of the E5 Cell, which it will only touch & not pass through.
If the StartingElement & EndingElement have the same value, a OneCellAnchor will be created.
Note that setting a value in this property will remove the value in the AbsolutePosition property because an anchor using said property is an AbsoluteAnchor, which doesn't use the AnchorPosition property.
Also note that for this property to work, the CellRange must be located within the same Worksheet as the PositionedElement.
