// .NAME vtkImageViewer2 - Display a 2D image.
// .SECTION Description
// vtkImageViewer2 is a convenience class for displaying a 2D image. It
// packages up the functionality found in vtkRenderWindow, vtkRenderer,
// vtkImageActor and vtkImageMapToWindowLevelColors into a single easy to use
// class. This class also creates an image interactor style
// (vtkInteractorStyleImage) that allows zooming and panning of images, and
// supports interactive window/level operations on the image. Note that
// vtkImageViewer2 is simply a wrapper around these classes.
//
// vtkImageViewer2 uses the 3D rendering and texture mapping engine
// to draw an image on a plane. This allows for rapid rendering,
// zooming, and panning. The image is placed in the 3D scene at a
// depth based on the z-coordinate of the particular image slice. Each
// call to SetSlice() changes the image data (slice) displayed AND
// changes the depth of the displayed slice in the 3D scene. This can
// be controlled by the AutoAdjustCameraClippingRange ivar of the
// InteractorStyle member.
//
// It is possible to mix images and geometry, using the methods:
//
// viewer->SetInput( myImage );
// viewer->GetRenderer()->AddActor( myActor );
//
// This can be used to annotate an image with a PolyData of "edges" or
// or highlight sections of an image or display a 3D isosurface
// with a slice from the volume, etc. Any portions of your geometry
// that are in front of the displayed slice will be visible; any
// portions of your geometry that are behind the displayed slice will
// be obscured. A more general framework (with respect to viewing
// direction) for achieving this effect is provided by the
// vtkImagePlaneWidget .
//
// Note that pressing 'r' will reset the window/level and pressing
// shift+'r' or control+'r' will reset the camera.
//
