[Insight-users] How to concatenate itk transformations

Hi Jian,

In ITK


   a) you can compose consecutive Affine transforms together,

   b) you can't compose two BSpline transforms

   c) you can set an Affine transform as the Bulk transform
              of a BSpline transform (which is equivalent to
              a pre-composition)



   Regards,


       Luis
