IGeometryServer2.Intersect Method

Returns an array of geometries where each result geometry R[i] is (array1[i] intersect G2. If G2 is an Envelope, then this is clipping.

[Visual Basic .NET]
Public Function Intersect ( _
    ByVal pSR As ISpatialReference, _
    ByVal pInGA1 As IGeometryArray, _
    ByVal pInG2 As IGeometry _
) As IGeometryArray

[C#]
public IGeometryArray Intersect (
    ISpatialReference pSR,
    IGeometryArray pInGA1,
    IGeometry pInG2
);

[C++]
HRESULT Intersect(
  ISpatialReference* pSR,
  IGeometryArray* pInGA1,
  IGeometry* pInG2,
  IGeometryArray** ppIntersectGA
);

[C++]
Parameters
pSR 
  pSR is a parameter of type ISpatialReference
pInGA1 
  pInGA1 is a parameter of type IGeometryArray
pInG2 
  pInG2 is a parameter of type IGeometry
ppIntersectGA [out, retval]
  ppIntersectGA is a parameter of type IGeometryArray

Remarks

This operation constructs the set-theoretic intersection between each element of the input array and InGeometry2. Each result is placed at the corresponding index in the output array – that is, Result[i] = InGeometryArray1[i] Intersect  InGeometry2. If inGeometryArray1[i] and InGeometry2 disjoint, the output is an empty geometry of the type with the minimum dimension between inGeometryArray1[i] and InGeometry2.

The figure below shows an example of the intersect operation. The input geometry array contains all geometries shown on the left of the figure with the exception of the central circular polygon. The output array contains the modified geometries shown in the right part of the figure. Note that two of the output points will be “empty” because their corresponding inputs are outside the circular polygon.
