[Insight-users] itk smart pointer

[Luis Ibanez]

Hi Xiahai,

There shouldn't be any problem with mixing SmartPointers
and the std::ifstream classes. There is something particular
happening with your code.

A common mistake is to create ITK objects with the New()
operator, and to assign them to normal raw pointers instead
of SmartPointer.  Please make sure that you create the object
as

     myObjectType::Pointer  toto = myObjectType::New();

DON'T DO:

     myObjectType *         toto = myObjectType::New();


In any case, from your short description it is very hard for
us to figure out what is wrong with your code.

Please post a minimal example of compilable code where you can
reproduce the problem that you are experiencing.


  Thanks


     Luis
