Moves the sides x units horizontally and y units vertically.
[Visual Basic .NET] Public Sub Offset ( _ ByVal X As Double, _ ByVal Y As Double _ )
[C#] public void Offset ( double X, double Y );
[C++]
HRESULT Offset(
double X,
double Y
);
[C++]
Parameters X X is a parameter of type double Y Y is a parameter of type double
Offset moves the position of the Envelope. A positive X value will shift the Envelope to the right and a negative value to the left. A positive Y value will shift the Envelope up and a negative value down. The Width and Height of the Envelope remain unchanged. Only the XMin, YMin, XMax, and YMax are changed.
The new position of the Envelope is as follows:
new XMin= old XMin + X
new YMin=old YMin + Y
new XMax=old XMax + X
new YMax=old YMax + Y
private void SetOffset()
{
IEnvelope envelope=new EnvelopeClass();
envelope.PutCoords(100, 100, 200, 200);
