The Z domain extent.
[Visual Basic .NET]
Public Sub GetZDomain ( _
ByRef outZMin As Double, _
ByRef outZMax As Double _
)
[C#]
public void GetZDomain (
ref double outZMin,
ref double outZMax
);
[C++]
HRESULT GetZDomain(
System.Double* outZMin,
System.Double* outZMax
);
[C++] Parameters outZMin [out]
outZMin is a parameter of type double* outZMax [out]
outZMax is a parameter of type double*
An alternative method to the GetZFalseOriginAndUnits method. Returns the minimum and maximum allowed Z values for a spatial reference. Use GetZFalseOriginAndUnits to obtain the Z precision (1/resolution) value.
//This code example shows how to get the Z domain extent of a dataset.
private void GetZDomain(IFeatureClass featureClass)
{
IGeoDataset geoDataset = featureClass as IGeoDataset;
//get access to SpatialReference through IGeoDataset
ISpatialReference spatialReference = geoDataset.SpatialReference;
//get the Z domain extent of the dataset
double zMin;
double zMax;
spatialReference.GetZDomain(out zMin, out zMax);
System.Windows.Forms.MessageBox.Show(zMin + ", " + zMax);
}
