code: public static <T extends ImageGray<T>> InterpolatePixelMB<Planar<T>>
  	createPixelPL(InterpolatePixelS<T> singleBand) {
  		return new InterpolatePixel_PL_using_SB<>(singleBand);
  	}
docs: Converts a single band interpolation algorithm into a mult-band interpolation for {@link Planar} images.
  NOTE: If a specialized interpolation exists you should use that instead of this the specialized code can
  reduce the number of calculations.
  
  @param singleBand Interpolation for a single band.
  @param <T> Single band image trype
  @return Interpolation for Planar images
