Detailed Description

Display a 2d image.

vtkImageViewer is a convenience class for displaying a 2d image. It packages up the functionality found in vtkRenderWindow, vtkRenderer, vtkActor2D and vtkImageMapper into a single easy to use class. Behind the scenes these four classes are actually used to to provide the required functionality. vtkImageViewer is simply a wrapper around them.
