|
This document is archived and information here might be outdated. Recommended version. |
Returns the coordinates of lower, left and upper, right corners.
[Visual Basic .NET]
Public Sub QueryCoords ( _
ByRef XMin As Double, _
ByRef YMin As Double, _
ByRef XMax As Double, _
ByRef YMax As Double _
)
[C#]
public void QueryCoords (
ref double XMin,
ref double YMin,
ref double XMax,
ref double YMax
);
[C++]
HRESULT QueryCoords(
System.Double* XMin,
System.Double* YMin,
System.Double* XMax,
System.Double* YMax
);
[C++] Parameters XMin [out]
XMin is a parameter of type double* YMin [out]
YMin is a parameter of type double* XMax [out]
XMax is a parameter of type double* YMax [out]
YMax is a parameter of type double*
Returns the XMin, YMin, XMax, and YMax values for the Envelope. These values can also be used to recreate the Envelope using PutCoords.
The following C# Code shows how to query for the XMin, YMin, XMax and YMax coordinates.
private void QueryCoordinates()
{
IEnvelope envelope = new EnvelopeClass();
envelope.PutCoords(100, 100, 200, 200);
double minX;
double minY;
double maxX;
double maxY;
envelope.QueryCoords(out minX, out minY, out maxX, out maxY);
String report = " \n" +
"LowerLeft X = " + minX + "\n" +
"LowerLeft Y = " + minY + "\n\n" +
"LowerRight X = " + maxX + "\n" +
"LowerRight Y = " + minY + "\n\n" +
"UpperLeft X = " + minX + "\n" +
"UpperLeft Y = " + maxY + "\n\n" +
"UpperRight X = " + maxY + "\n" +
"UpperRight Y = " + maxY;
System.Windows.Forms.MessageBox.Show(report);
}
' Given the Envelope m_pEnveLope the QueryCoords method returns the values
' of the min and max coordinates.
Private Sub QueryCoords(ByRef m_pEnvelope As IEnvelope)
Dim dXmin As Double, dYmin As Double, dXmax As Double, dYmax As Double
m_pEnvelope.QueryCoords(dXmin, dYmin, dXmax, dYmax)
End Sub
