//! The class PixelInterpolation is used to compute a Pixel <br>
//!            value on non-integer Image coordinate. This Pixel type <br>
//!	      is called SubPixel . <br>
//!          PixelInterpolation is the default and is the simplest one, <br>
//!	      SubPixel value on non-integer Image coordinate is the <br>
//!	      value of the nearest Pixel at integer coordinate. <br>
//!	    The user can create a new kind of PixelInterpolation with a <br>
//!	      new algorithm by creating a new derived PixelInterpolation <br>
//!	      class and redefined Interpolate() method. <br>
//!	    If V1  is the value of the nearest Image Pixel <br>
//!		V = V1 is the Image SubPixel value on non-integer <br>
//!	      coordinate (FX,FY) <br>
