BufferedImage imageScaling

[MINGxDOG]

Start with this given part..how to do backward mapping with bi-linear interpolation and Nearest Neighbor Interpolation ?

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import javax.swing.*;
import java.util.*;
import java.lang.Math.*;


public class ImageProcessor
{	
	public static BufferedImage convert(Image img)
	{
		BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
		Graphics bg = bi.getGraphics();
		bg.drawImage(img, 0, 0, null);
		bg.dispose();
		return bi;
	}
	public static BufferedImage imageScaling(Image img, double sX, double sY, int type)
	{

	BufferedImage bufImg = convert(img);
		
		int width = bufImg.getWidth();
		int height = bufImg.getHeight();
		
		double newWidth = width * sX;
		double newHeight = height * sY;
				
		for(int j = 0; j < newHeight; j++)
		{

			for(int i = 0; i < newWidth; i++)
			{

			
			}
		}
		return bufImg;

	}
}
