[Insight-developers] Smart Pointer (continue)

[Yinpeng Jin]

I think I should also give the "background":
I overwrited the SetInput()


SetInput(InputImagePointer input)
{
  Superclass::SetInput(input);
.......
  itk::ImageRegionIteratorWithIndex <InputImageType> iit(this->GetInput(),
region);
  // compiler error here

}


and typedefs in .h:
  typedef TInputImage InputImageType;
  typedef typename TInputImage::Pointer InputImagePointer;


here is the error message again:
error C2664: '__thiscall itk::ImageRegionIteratorWithIndex<class

itk::Vector<unsigned char,3>,2> >)'

so, how to fix it?

thanks.
