+// .NAME wxvtkImageViewer2 - Display a 2D image.
+// .SECTION Description
+// wxvtkImageViewer2 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
+// wxvtkImageViewer2 is simply a wrapper around these classes.
+//
+// wxvtkImageViewer2 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.
