主要代碼如下：
package chapter5;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.IOException;

/**

  public class LvJingFilter extends AbstractBufferedImageOp {
  int[] fogLookUp = new int[257];//霧化風格顏色查找表
  int[] rainbowLookup ;
  public LvJingFilter(){

  }
  public BufferedImage filter(BufferedImage src,BufferedImage dest){
  int width = src.getWidth();
  int height = src.getHeight();
  if(dest == null){
  dest = creatCompatibleDestImage(src,null);
  }
  int inpixels[] = new int[width*height];
  int outpixels[] = new int[width*height];
  getRGB(src,0,0,width,height,inpixels);
  int index = 0;
  for(int row=0;row<height;row++){
  int ta = 0,tr = 0,tg = 0,tb = 0;
  for(int col=0;col

  return dest;

  }
  //霧風格顏色查找表//40,41,42,.....127,127,127,....127,128,129,...,255
  public void buildFogLookupTable(){
  //顏色查找表
  int fogLimit = 40;
  for(int i=0; i

  }

  }

  //彩虹風格顏色查找表
  public void buildRainBowLookupTable(){
  java.net.URL imageURL = this.getClass().getResource("rainbow.jpg");
  if(imageURL !=null){
  try {
  BufferedImage image = ImageIO.read(imageURL);
  int width = image.getWidth();
  int height = image.getHeight();
  rainbowLookup = new int[width];
  int[] inPixels = new int[width*height];
  getRGB(image,0,0,width,height,inPixels);
  for(int col=0;col<width;col++){
  rainbowLookup[col] = inPixels[col];
  }
  } catch (IOException e) {
  // e.printStackTrace();
  System.out.println("An error occured when loading the image icon...");
  }
  }

  }
  }
  測試代碼同上
