Often times developers face the need to connect ITK and VTK pipelines to handle
image data. For this purpose, image data importer and exporter classes
have been implemented both in ITK and VTK. However, as evident from frequent questions in
the ITK and VTK users and developers mailing list, usage of these classes is not
straight forward. Furthermore, the difficulty gets more challenging with the need to
handle different pixel types. For these reasons, an effort was made to write Image IO classes that
encapsulate all the intricacies and provide users with easy to use API. This article
describes these Image IO classes and present an example to demonstrate how to use
these classes.
