EnvelopeBuilderEx Constructor(Coordinate2D,Coordinate2D,SpatialReference)

In This Topic

Creates a new instance of the EnvelopeBuilderEx class.

Syntax

C#
Visual Basic (Declaration)

public EnvelopeBuilderEx( 
   Coordinate2D minCoord,
   Coordinate2D maxCoord,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal minCoord As Coordinate2D, _
   ByVal maxCoord As Coordinate2D, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

minCoord: Lower left corner of the envelope.
maxCoord: Upper right corner 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 coordinate values are NaN, then the envelope is set to empty.

Example

Update Coordinates of an Envelope

Coordinate2D minCoord = new Coordinate2D(1, 3);
Coordinate2D maxCoord = new Coordinate2D(2, 4);

Coordinate2D c1 = new Coordinate2D(0, 5);
Coordinate2D c2 = new Coordinate2D(1, 3);

      
// use the EnvelopeBuilderEx.  This constructor doesn't need to run on the MCT.

EnvelopeBuilderEx builderEx = new EnvelopeBuilderEx(minCoord, maxCoord);
// builderEx.XMin, YMin, Zmin, MMin  = 1, 3, 0, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 2, 4, 0, double.Nan

// set XMin.  if XMin > XMax; both XMin and XMax change
builderEx.XMin = 6;
// builderEx.XMin, YMin, ZMin, MMin  = 6, 3, 0, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 6, 4, 0, double.Nan

// set XMax
builderEx.XMax = 8;
// builderEx.XMin, YMin, ZMin, MMin  = 6, 3, 0, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 8, 4, 0, double.Nan

// set XMax.  if XMax < XMin, both XMin and XMax change
builderEx.XMax = 3;
// builderEx.XMin, YMin, ZMin, MMin  = 3, 3, 0, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 3, 4, 0, double.Nan

// set YMin
builderEx.YMin = 2;
// builderEx.XMin, YMin, ZMin, MMin  = 3, 2, 0, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 3, 4, 0, double.Nan

// set ZMin.  if ZMin > ZMax, both ZMin and ZMax change
builderEx.ZMin = 3;
// builderEx.XMin, YMin, ZMin, MMin  = 3, 2, 3, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 3, 4, 3, double.Nan

// set ZMax.  if ZMax < ZMin. both ZMin and ZMax change
builderEx.ZMax = -1;
// builderEx.XMin, YMin, ZMin, MMin  = 3, 2, -1, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 3, 4, -1, double.Nan

builderEx.SetZCoords(8, -5);
// builderEx.XMin, YMin, ZMin, MMin  = 3, 2, -5, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 3, 4, 8, double.Nan


builderEx.SetXYCoords(c1, c2);
// builderEx.XMin, YMin, ZMin, MMin  = 0, 3, -5, double.Nan
// builderEx.XMax, YMax, ZMax, MMax = 1, 5, 8, double.Nan


builderEx.HasM = true;
builderEx.SetMCoords(2, 5);

var geomEx = builderEx.ToGeometry();
