[vtkusers] Usage of VTK Coordinate Class

[rahul indoria]

Hi,
    I am working on *vtkcoordinate* class, as my task is :

*I have an image and the end vertices of an image are :*

a:  0 122 0
b:  62  100 0
c:  128  140 0
d:  188 122 0

My question is how can i move the coordinates to different location.

Could you please suggest me some member function of this class and how can
i use this?

Please help, it`s really very urgent for me.

Looking forward your reply soon.
