ICurve2.PutCoordsEx Method

Sets this segment's endpoints to 'from' and 'to'.

[Visual Basic .NET]
Public Sub PutCoordsEx ( _
    ByVal from As IPoint, _
    ByVal to As IPoint _
)

[C#]
public void PutCoordsEx (
    IPoint from,
    IPoint to
);

[C++]
HRESULT PutCoordsEx(
  IPoint* from,
  IPoint* to
);

[C++]

Parameters
from 

  from is a parameter of type IPoint
to 

  to is a parameter of type IPoint

Product Availability

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

Description

PutCoordsEx allows both the fromPoint and the toPoint to be set simultaneously. 
A Conformal Transformation based on the original points and the new points
is applied to the curve.
