[Insight-users] warping a clound of points when the target landmarks form a straight line

[Ramón Casero Cañas]

Just a quick observation on a warning given by 
BSplineScatteredDataPointSetToImageFilter.

   Date:      $Date: 2010-03-02 19:26:09 $
   Version:   $Revision: 1.12 $

I have some includes in my file

http://code.google.com/p/gerardus/source/browse/trunk/matlab/ItkToolbox/ItkPSTransform.cpp

#include "itkElasticBodySplineKernelTransform.h"
#include "itkElasticBodyReciprocalSplineKernelTransform.h"
#include "itkThinPlateSplineKernelTransform.h"
#include "itkThinPlateR2LogRSplineKernelTransform.h"
#include "itkVolumeSplineKernelTransform.h"

and it compiles without warnings or errors.

But if I add the line

#include "itkBSplineScatteredDataPointSetToImageFilter.h"

Then I get the warnings
