[Insight-users] "Stupid" question about SmartPointer

[Vincent Daanen]

Hi itk-users,

Currently writing a test program for volume registration, I'd like to 
choose dynamically the metric.

So I think to such a thing :
    itk::ImageToImageMetric *pMetric;

    swicth (metricChoice)
    {
       case MI :
          typedef 
itk::MutualInfomationimageToImageMetric<InternalImageType, 
InternalImageType> MetricType;
          MetricType::Pointer mi_metric = MetricType::New();
          mi_metric->....          //mi_metric intialisation
         
          pMetric = mi_metric->GetPointer();
         break;
      
        case NMI :
        ...
    }

My problem is that I'm afraid that mi_metric will be deleted at the end 
of the "case MI :" statement. am I right ?
If yes, is there a way to still use this way of programming (I'm sure it 
is possible but I do not find the way yet) !

Thanks for your help

 Vince
