[Insight-users] Image assignment does not work

[wanlin]

What about
void applyFilter(InternalImageType:
:Pointer & image,
itk::ImageToImageFilter<InternalImageType,InternalImageType>::Pointer
filter)

image=filter->GetOutput();//here image pointer inside function has been
changed, however, the image outside the function does not.
