IEnvelope* clipperEnvelope
);
[C++]Parameters
clipperEnvelopeclipperEnvelope is a parameter of type IEnvelope

Description
The Clip method clips the geometry of the feature that is receiving the method call. The Clip method does not return an envelope. The geometry that is clipped will depend on what is Contained by the input clipperEnvelope.
Remarks
Use QueryClipped or QueryClippedDense methods to send the results to a different polygon.
ITopologicalOperator methods must be applied on high-level
geometries only. High-Level geometries are point, multipoint,
polyline and polygon. To use this method with
low-level geometries such as segments (Line, Circular Arc, Elliptic
Arc, Bézier Curve), paths or rings, they must be wrapped
into high-level geometries types.
//The following code shows to wrap a line segment into a polyline in C#
//Assume a line (line1 as ILine) is already created
object obj = Type.Missing;
ISegmentCollection segCollection = new PolylineClass() as ISegmentCollection;
segCollection.AddSegment((ISegment)line1, ref obj, ref obj);
//Set the spatial reference on the new polyline
//The spatial reference is not transfered automatically from the segments
IGeometry geom = segCollection as IGeometry;
geom.SpatialReference = spatialRef;
//Can now be used with ITopologicalOperator methods
