IEnvelope2 Interface

Provides access to members that extend the IEnvelope interface.

Description

IEnvelope2 allows the minimum and maximum M and Z attributes of the Envelope to be queried and set simultaneously to avoid complications and inconsistencies of setting them individually.

IEnvelope2.PutMCoords Method

Sets the minimum and maximum M values simultaneously.

Public Sub PutMCoords ( _
    ByVal MMin As Double, _
    ByVal MMax As Double _
)
public void PutMCoords (
    double MMin,
    double MMax
);

Description

Sets the MMin and MMax simultaneously. This avoids complications of setting MMin and MMax individually in which they could become inconsistent.

IEnvelope2.PutZCoords Method

Sets the minimum and maximum Z values simultaneously.

Public Sub PutZCoords ( _
    ByVal ZMin As Double, _
    ByVal ZMax As Double _
)
public void PutZCoords (
    double ZMin,
    double ZMax
);

Description

Sets the ZMin and ZMax simultaneously. This avoids complications of setting ZMin and ZMax individually in which they could become inconsistent.

public static void TestPutZCoords()

          {

              const double ZMin = -10;

              const double ZMax = -5;

  

              IEnvelope2 envelope = GetEnvelopeGeometry() as IEnvelope2;

  

              envelope.PutZCoords(ZMin, ZMax);

         }

IEnvelope2.QueryMCoords Method

Queries the minimum and maximum M values simultaneously.

Public Sub QueryMCoords ( _
    ByRef MMin As Double, _
    ByRef MMax As Double _
)
public void QueryMCoords (
    ref double MMin,
    ref double MMax
);

Description

Returns the values of MMin and MMax respectively.

IEnvelope2.QueryZCoords Method

Queries the minimum and maximum Z values simultaneously.

Public Sub QueryZCoords ( _
    ByRef ZMin As Double, _
    ByRef ZMax As Double _
)
public void QueryZCoords (
    ref double ZMin,
    ref double ZMax
);

Description

Returns the values of ZMin and ZMax respectively.

public static void TestQueryZCoords()

          {

              IEnvelope2 envelope = GetEnvelopeGeometry() as IEnvelope2;

  

              double zMin, zMax;

  

              envelope.QueryZCoords(out zMin, out zMax);

  

              //zMin = -14.131

              //zMax = -4.131

         }
