写的一个小玩具,用来把一张图分割成九宫图,满足发图就想发九张的强迫症

package pictureDivide;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;public class NineZoneDiv{    public static void main(String[] args){        //imageIO或者fileIO能够读取图像        //BufferedImage创建一个实际的图像缓冲区,可以直接操作像素        //bufferedImage.getSbuImage返回由指定矩形区域定义的子图像。        //返回的 BufferedImage 与源图像共享相同的数据数组。        String scrImageFile = "poi.jpg";        String targetDir = "nineZornPoi";        BufferedImage img = null;        BufferedImage scrImage = null;        try {            scrImage = ImageIO.read(new File(scrImageFile));        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        int scrHeight = scrImage.getHeight();        int divHeight = scrHeight / 3;        int scrWidth = scrImage.getWidth();        int divWidth = scrWidth / 3;        System.out.println("width" + scrWidth);        System.out.println("height" + scrHeight);        String fileName = null;        for(int i = 0; i < 3; i++){            for(int j = 0; j < 3; j++){                img = scrImage.getSubimage(j * divWidth, i * divHeight, divWidth, divHeight);                fileName = targetDir +"_" + i + "_" + j + ".jpg";   //文件名                File file = new File(fileName);                try {                    ImageIO.write(img, "JPEG", file);                } catch (IOException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }                System.out.println("save" + i + j);            }        }        System.out.println("succes");    }}
