[Insight-users] displaying image error

[Luis Ibanez]

Hi Alireza,

The code in this example is not intended to display an image.

In fact, there is nothing in ITK that will display an image.
ITK provides functionalities for segmentation and registration
of image, but not for visualization.

You may wan to use VTK  for displaying images.

VTK and ITK are quite complementary, and usually
you want to use them together in any image processing
application.

You will find examples of how to use ITK along with VTK
in the directory:

          InsightlApplications/Auxiliary/vtk



If you prefer to continue your study of ITK, you can
simply save the image using the itkImageFileWriter
and then open it with any image viewer available in
your machine.


Regards,


     Luis
