[Insight-developers] Writing Transforms

[Julien Jomier]

Hi Vince,

The itkBSplineDeformableTransform does have a GetParameters() and I 
think we have used the TransformFileWriter to write this type of 
transform on disk.

By definition from the TransformBase class all the transforms should 
implement a Get/SetParameters() (this is the only way to pass the 
transform to the Optimizer).

What kind of error did you get when trying to write the B-Spline transform?
