Intersection(Envelope) Method

C#
Visual Basic (Declaration)

public void Intersection( 
   Envelope envelope
)

Public Sub Intersection( _
   ByVal envelope As Envelope _
)

Parameters

envelope: The envelope to intersect with.

Exception	Description
System.ArgumentNullException	The input envelope is null.

Sets the envelope builder equal to the intersection of the base envelope and the input envelope. The XMin and YMin of the resulting envelope builder is the maximum XMin and YMin respectively between the base and input envelopes, and the XMax and YMax 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 NaN.).

Intersect

C#

// use the convenience builders - don't need to run on the MCT.
Envelope env1 = EnvelopeBuilder.CreateEnvelope(0, 0, 1, 1, SpatialReferences.WGS84);
Envelope env2 = EnvelopeBuilder.CreateEnvelope(0.5, 0.5, 1.5, 1.5, SpatialReferences.WGS84);

bool intersects = env1.Intersects(env2); // true
Envelope env3 = env1.Intersection(env2);


// or use the builder constructor - need to run on the MCT.
using (var builder = new EnvelopeBuilder(0, 0, 1, 1, SpatialReferences.WGS84))
{
  intersects = builder.Intersects(env2);  // true
  env3 = builder.Intersection(env2);
}

// or use the builderEx constructors = don't need to run on the MCT.
EnvelopeBuilderEx builderEx = new EnvelopeBuilderEx(0, 0, 1, 1, SpatialReferences.WGS84);
intersects = builderEx.Intersects(env2);
builderEx.Intersection(env2);   // note this sets the builder to the intersection
env3 = builderEx.ToGeometry() as Envelope;
