图片填充文字

String fileName="/Users/liuhuan/Downloads/123.png";
        //得到文件
        File srcImgFile = new File(fileName);
        //文件转化为图片
        Image srcImg = ImageIO.read(srcImgFile);

	// 填充图片
        ImageIcon imgIcon = new ImageIcon("/Users/liuhuan/Downloads/456.png");
        //得到Image对象。
        Image img = imgIcon.getImage();
        g.drawImage (img, 100, 200, null);
        g.dispose();

        FileOutputStream outImgStream = new FileOutputStream("/Users/liuhuan/Downloads/result123.png");

//        g.setColor(markContentColor);
        //设置字体
