    00031 // .NAME vtkImageMapToColors16 - map the input image through a lookup table
    00032 // .SECTION Description
    00033 // The vtkImageMapToColors16 filter will take an input image of any valid
    00034 // scalar type, and map the first component of the image through a
    00035 // lookup table.  The result is an image of type VTK_UNSIGNED_CHAR.
    00036 // If the lookup table is not set, or is set to NULL, then the input
    00037 // data will be passed through if it is already of type VTK_UNSIGNED_CHAR.
