Many thanks, I'm on it, I'll get back to you when it works. But on a
related note, I'd like to mention that the following snippet compiles fine
typedef typename
itk::BSplineControlPointImageFunction<ImageType, double>
EvalFunctionType;
typename EvalFunctionType::Pointer function = EvalFunctionType::New();
while this spits an error which seems to be an abstract method not being
implemented for TCoordRep=float (the change is "double" for "float")
typedef typename
itk::BSplineControlPointImageFunction<ImageType, float>
EvalFunctionType;
typename EvalFunctionType::Pointer function = EvalFunctionType::New();
The error is
