[Insight-developers] GradientVectorFlowImageFilter internal image type

[Gaëtan Lehmann]

Hi,

In order to add GradientVectorFlowImageFilter in wrapitk, I'd like to  
make a change in that filter: I want to expose the pixel type used in  
the internal image type in the template parameter, with the default to  
the current value (double).

   template <class TInputImage, class TOutputImage>
   class ITK_EXPORT GradientVectorFlowImageFilter : public  
ImageToImageFilter<TInputImage, TOutputImage>

would become

   template <class TInputImage, class TOutputImage, class  
TInternalPixel=double>
   class ITK_EXPORT GradientVectorFlowImageFilter : public  
ImageToImageFilter<TInputImage, TOutputImage>

There shouldn't be any backward compatibility issue that way. I don't  
know well that class though, so I have an important question:
Does that change look reasonable? I mean, is it relevant to use a  
different internal pixel type than double - float for example?

Regards,

Gaëtan
