Remarks
The array returned by the PolylineCusps property is an index into the array returned by the IInkStrokeDisp::GetPoints method. Each index in the PolylineCusps property corresponds to a point in the array returned by the GetPoints method that is a cusp of the points of the stroke.
A cusp is a point on the stroke where the direction of writing changes in a discontinuous fashion. For example, if the stroke represents the capital letter "L", this property returns three cusps: two corresponding to the first and last control points on the stroke and the third representing the corner of the "L".
The location of a cusp can be determined by using the cusp as an index into the array returned by the GetPoints method.
