[Insight-users] ComputOffset in the class CenteredAffineTransform

[Luis Ibanez]

Hi Shuzai


1) What version of ITK are you using ?

2) You shouldn't need to call ComputeOffset()
    in a modern version of ITK.

3) You shouldn't use the CenteredAffineTransform()
    in a modern version of ITK (e.g. ITK > 3.0)
    since now the standard itk::AffineTransform
    also incorporates a SetCenter() method.


Regards,


     Luis
