RemovePoint removes the Point at the specified index position from the Polygon; points with an index position greater than pointIndex will have their index position reduced by 1. Removing a Point from a Polygon changes the shape of the Polygon, so that the two points either side of pointIndex will be directly connected. When used on a multipart Polygon, this method operates only on the first ring of the Polygon; see the RemovePointAt(Int32, Int32) overload to remove a Point from a specific ring in a multipart Polygon.

Note, if either the first or last Point is removed from a closed Polygon ring, the Polygon no longer describes a closed shape; refer to the Close()()() or Simplify(Polygon) for options to rectify this.
