      • scale

        public java.awt.image.BufferedImage scale​(java.awt.image.BufferedImage img,
                                          double x,
                                          double y)
        Scales pixels of given buffered image by using following formula

        P[x, y] = round( P[x * sX , y * sY] )

        where sX, sY are scale factors along X & Y axis respectively, they are floating point values

        Parameters:
        img - Buffered image to be scaled
        x - Scale factor along X
        y - Scale factor along X
        Returns:
        Scaled buffered image, which is other than original image
