[Insight-developers] Smart Pointer (continue)

[Luis Ibanez]

Yinpeng,


You have to replace the current iterator
with a const iterator.

Replace:

    ImageRegionIteratorWithIndex

with:

     ImageRegionConstIteratorWithIndex


For that, you will also have to add a:

#include "itkImageRegionConstIteratorWithIndex.h"


The constructors of const iterators accept :

        "const Image *"

as argument.
