Java 实现灰度图转真彩图

将以上的图片，jpg png 都可以，转为有颜色的

2 实现

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.image.Raster;
import java.io.File;

public class DatUtils {
   

    public static void main(String[] args) {
   
        File file = new File("C:\\Users\\\\55\\1.jpg");
        File file1 = new File("C:\\Users\\\\55");
        System.out.println(picGrayToColour(file.getPath(),file1.getPath(),"33.jpg"));

    }
    /**
     * 灰度图转真彩图
     * @param path-灰度图路径
     * @param outPath-真彩图输出路径
     */
    public static boolean picGrayToColour(String path, String outPath, String picName){
   
        try {
   
            File file = new File(path);
            BufferedImage bufferedImage = ImageIO.read(file);
            BufferedImage bImage=new BufferedImage(bufferedImage.getWidth(),bufferedImage.getHeight(),BufferedImage.TYPE_4BYTE_ABGR);
            Raster data = bufferedImage.getData();
            for
