Adjusts to include only the area also included by inEnvelope.
[Visual Basic .NET] Public Sub Intersect ( _ ByVal inEnvelope As IEnvelope _ )
[C#] public void Intersect ( IEnvelope inEnvelope );
[C++]
HRESULT Intersect(
IEnvelope* inEnvelope
);
[C++] Parameters inEnvelope
inEnvelope is a parameter of type IEnvelope*
Sets the Envelope equal to the intersection of the base Envelope and the input Envelope. The XMin and YMin of the resulting Envelope is the maximum XMin and YMin respectively between the base and input Envelopes, and the XMax and YMax of the resulting Envelope is the minimum XMax and YMax respectively between the base and input Envelopes. If the resulting XMin > XMax, or YMin > YMax, then the Envelope is Empty (and all XMin, XMax, YMin, and YMax are undefined.).
public void Intersect()
{
IEnvelope envelope1 = new EnvelopeClass();

envelope1.PutCoords(100, 100, 200, 200);
envelope2.PutCoords(150, 150, 250, 250);
envelope1.Intersect(envelope2);
IPoint lowerLeft = envelope1.LowerLeft;
IPoint lowerRight = envelope1.LowerRight;
IPoint upperLeft = envelope1.UpperLeft;
IPoint upperRight = envelope1.UpperRight;
String report = "LowerLeft X = " + lowerLeft.X + "\n" +
"LowerLeft Y = " + lowerLeft.Y + "\n\n" +

'The example shows how to intersect 2 envelopes. The result is put in the first envelope.
