[Insight-users] weird thing happen when I try to write template function

[Baoyun Li]

Dear All:

I am trying to write some template function. 

Here is  my function, it just passed ReaderType::Pointer from the main program


template <class TInputImage>
void IsotropicResample( TInputImage* inputimage )
{
  
    const unsigned int Dimension=3;
    typedef   short   OutputPixelType;
    typedef itk::Image< OutputPixelType,   Dimension >   OutputImageType;
 
   typedef itk::ImageFileWriter< OutputImageType >  WriterType;
 
   WriterType::Pointer writer = WriterType::New();
 
   writer->SetFileName("../data/test.hdr");
   writer->SetInput( inputimage->GetOutput() );
   
  try
     {
     writer->Update();
     }
   catch( itk::ExceptionObject & excep )
     {
     std::cerr << "Exception caught !" << std::endl;
     std::cerr << excep << std::endl;
     }
;

};

////// in the main function, we call the function as following

main()
{
  typedef itk::ImageFileReader< InputImageType  >  ReaderType;
  ReaderType::Pointer reader = ReaderType::New();
   IsotropicResample <ReaderType> (reader );
}

When I run the program through command line, everything is ok, I got the test.hdr as output.

But when I debug program, the program catch error and goes to the catch branch.

warning RTTI symbol not found, 
FileReader<itk::Image<short, 3u>, itk::DefaultConvertPixelTraits<short> >'

  try
     {
     writer->Update();
     }
   catch( itk::ExceptionObject & excep )
     {
     std::cerr << "Exception caught !" << std::endl;
     std::cerr << excep << std::endl;
     }

However, the result is still there?

Can sombody teach me how to solve this problem??


Thanks

Baoyun
