// .NAME vtkImageRectangularSource - Create a binary image of an rectangular.
// .SECTION Description
// vtkImageRectangularSource creates a binary image of a ellipsoid.  It was created
// as an example of a simple source, and to test the mask filter.
// It is also used internally in vtkImageDilateErode3D.
