IEnvelope.OffsetZ Method

Moves the sides z units.

[Visual Basic .NET]
Public Sub OffsetZ ( _
    ByVal Z As Double _
)

[C#]
public void OffsetZ (
    double Z
);

[C++]
HRESULT OffsetZ(
  double Z
);

[C++]
Parameters
Z 

  Z is a parameter of type double

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

OffsetZ shifts the Z attributes of the Envelope. The Depth remains unchanged.

new ZMin = old ZMin + Z
new ZMax = old ZMax + Z

[C#]

public static void TestOffsetZ()

{

const double Offset = 14.928;

IEnvelope2 envelope = GetEnvelopeGeometry() as IEnvelope2;

double beforeXMin, beforeXMax, beforeYMin, beforeYMax;

envelope.QueryCoords(out beforeXMin, out beforeYMin, out beforeXMax, out beforeYMax);

double beforeZMin, beforeZMax;
