Description

Queries the ith Point from the PointCollection.  The first Point in the PointCollection has index 0, and the last Point has index equal to PointCount - 1.  (Alternatively, the last Point in the PointCollection can be referenced using index -1.).

Remarks

Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.
