[Insight-users] Problem for reading vtk images

[Luis Ibanez]

Hi Alex,


   Why are you using the ImageIO classes directly ?


     You *should not* need to access them at all.


You can read image by simply using the ImageFileReader:



   typedef itk::ImageFileReader< ImageType >   ReaderType;

   ReaderType::Pointer  reader = ReaderType::New();

   reader->SetFileName("myImage.vtk");

   try
     {
     reader->Update();
     }
   catch( itk::ExceptionObject & excp )
     {
     std::cerr << excp << std::endl;
     return EXIT_FAILURE;
     }




The ImageFileReader will deal with the ImageIOFactories for you.



Please give us more details about what you are doing,


    Thanks



       Luis
