ITransform3D.Scale3D Method

Scales the object about the specified origin point. sx, sy, and sz are the scaling factors for the x, y, and z dimensions repectively.

[Visual Basic .NET]
Public Sub Scale3D ( _
    ByVal Origin As IPoint, _
    ByVal sx As Double, _
    ByVal sy As Double, _
    ByVal sz As Double _
)

[C#]
public void Scale3D (
    IPoint Origin,
    double sx,
    double sy,
    double sz
);

[C++]
HRESULT Scale3D(
  IPoint* Origin,
  double sx,
  double sy,
  double sz
);

[C++]

Parameters
Origin 

  Origin is a parameter of type IPoint*
sx 

  sx is a parameter of type double
sy 

  sy is a parameter of type double
sz 

  sz is a parameter of type double

Product Availability

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