CreateEnvelope(Coordinate2D,Coordinate2D,SpatialReference) Method

Convenience method to create a new instance of the Envelope class.

Syntax

C#
Visual Basic (Declaration)

public static Envelope CreateEnvelope( 
   Coordinate2D minCoord,
   Coordinate2D maxCoord,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateEnvelope( _
   ByVal minCoord As Coordinate2D, _
   ByVal maxCoord As Coordinate2D, _
   Optional ByVal spatialReference As SpatialReference _
) As Envelope

Parameters

minCoord: Lower left corner of the envelope.
maxCoord: Upper right corner of the envelope.
spatialReference: (Optional) The SpatialReference. The default value is null.

Return Value

An Envelope

Remarks

The envelope is normalized to ensure XMin <= XMax, YMin <= yMax. If any of the xy-coordinate values are NaN, then the envelope is set to empty.

Example

// determine intersection between two polygons

Envelope env1 = EnvelopeBuilder.CreateEnvelope(new Coordinate2D(3.0, 2.0), new Coordinate2D(6.0, 6.0));
Polygon poly1 = PolygonBuilder.CreatePolygon(env1);

Envelope env2 = EnvelopeBuilder.CreateEnvelope(new Coordinate2D(1.0, 1.0), new Coordinate2D(4.0, 4.0));
Polygon poly2 = PolygonBuilder.CreatePolygon(env2);

Polygon polyResult = GeometryEngine.Instance.Intersection(poly1, poly2) as Polygon;

Requirements

Target Platforms: Windows 10, Windows 8.1, Windows 7
