java 图片上写入文字

以下方法在fc6下测试通过,假设用户的jre路径为 /usr/java/jdk1.6.0_03/jre/
#cd /usr/java/jdk1.6.0_03/jre/lib/fonts
#sudo mkdir fallback
将C:\WINDOWS\Fonts\simsun.ttc拷贝到 /usr/java/jdk1.6.0_03/jre/lib/fonts/fallback文件夹内 ok!

//读取图片文件，得到BufferedImage对象
BufferedImage bimg=ImageIO.read(new FileInputStream("c:/u1.jpg"));
//得到Graphics2D 对象
Graphics2D g2d=(Graphics2D)bimg.getGraphics();
//设置颜色和画笔粗细
g2d.setColor(Color.RED);
g2d.setStroke(new BasicStroke(5));
g2d.setFont(new Font("Serif", Font.PLAIN, 13));
//绘制图案或文字
g2d.drawString("陈克永", 174, 257);
g2d.drawString("2015", 279, 257);
g2d.drawString("8", 343, 257);

//保存新图片
ImageIO.write(bimg, "JPG",new FileOutputStream("c:/u2.jpg"));

public String lpzjImg(){
this.getResponse().setContentType("image/jpeg;charset=UTF-8");
this.getResponse().setHeader("Content-Disposition", "attachment;filename=lpzj.jpg");
