[Insight-users] Ref. Smart pointers as function argument

[Frederic Perez]

Hello Ricardo, Luis, and Insight-users,

you might also consider using ConstPointer

void foo(InputImageType::ConstPointer input);

This disallows the use of ImageRegionIterator to traverse input, forcing you
to use something like

itk::ImageRegionConstIterator<InputImageType> itI(input, region);

My two cents,

Frederic Perez
