[Insight-users] ImageViewer for itkImage?

[Arunachalam Kana]

Hi Nitin,

 

I do not work with dicom files, however i just had a quick look into the
itk files and found an example to view dicom images.

Please have a look at the file:

InsightApplication/dicomimageviewer/dicomimageviewer.cpp

 

Dicomimageviewer.ccp code given below:

    {

    std::cout << exception << std::endl;

    return 1;

    }

  std::cout << "...Done Loading File" << std::endl;

 

  typedef fltk::Image2DViewer<ImageType::PixelType> ImageViewerType;

  ImageViewerType::Pointer viewer = ImageViewerType::New();

 

  viewer->SetLabel( fName );

  viewer->SetImage( reader->GetOutput() );

  viewer->Show();

 

  Fl::run();

  

  return 1;

  }

 

Hope this helps you.
