IGeometryServer2.ConvexHull Method

Computes the convex hull of the input geometries

[Visual Basic .NET]
Public Function ConvexHull ( _
    ByVal pSR As ISpatialReference, _
    ByVal pInGeometryArray As IGeometryArray _
) As IGeometry

[C#]
public IGeometry ConvexHull (
    ISpatialReference pSR,
    IGeometryArray pInGeometryArray
);

[C++]
HRESULT ConvexHull(
  ISpatialReference* pSR,
  IGeometryArray* pInGeometryArray,
  IGeometry** pHull
);

[C++]

Parameters
pSR 

  pSR is a parameter of type ISpatialReference
pInGeometryArray 

  pInGeometryArray is a parameter of type IGeometryArray
pHull [out, retval]

  pHull is a parameter of type IGeometry

Remarks

The convex hull of a set of points, polylines and polygons is shown below. If all the inputs are collinear, than a polyline will be returned instead of a polygon. If all inputs are located at a single point, then that point will be returned.
