EnvelopeBuilderEx Constructor(Double,Double,Double,Double,SpatialReference)

Initializes a new instance of the EnvelopeBuilderEx class.

Syntax

C#
Visual Basic (Declaration)

public EnvelopeBuilderEx( 
   double xMin,
   double yMin,
   double xMax,
   double yMax,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal xMin As Double, _
   ByVal yMin As Double, _
   ByVal xMax As Double, _
   ByVal yMax As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

xMin: Lower left corner x value of the envelope.
yMin: Upper right corner y value of the envelope.
xMax: Lower left corner x value of the envelope.
yMax: Upper right corner y value of the envelope.
spatialReference: (Optional) The SpatialReference. The default value is null.

Remarks

The resulting envelope is normalized to ensure its XMin <= XMax and YMin <= YMax. If any of the input values are NaN, then the envelope is set to empty.

Example

// Use a builder convenience method or use a builder constructor.

// Builder convenience methods don't need to run on the MCT.
Envelope envelope = EnvelopeBuilder.CreateEnvelope(100.0, 100.0, 500.0, 500.0);

// shrink the envelope by 50%
Envelope result = envelope.Expand(0.5, 0.5, true);

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (EnvelopeBuilder eBuilder = new EnvelopeBuilder(100.0, 100.0, 500.0, 500.0))
  {
    // shrink by 50%
    eBuilder.Expand(0.5, 0.5, true);

    result = eBuilder.ToGeometry();
  }
});

// builderEx constructors don't need to run on the MCT.
EnvelopeBuilderEx builderEx = new EnvelopeBuilderEx(100.0, 100.0, 500.0, 500.0);
builderEx.Expand(0.5, 0.5, true);
envelope = builderEx.ToGeometry() as Envelope;
