崩溃啦。。。救命啊。。。关于Image中DrawString

Question

BufferedImage image=ImageIO.read(new File(fileName));//读取图片
JLabel jl=new JLabel(new ImageIcon(image)); //把图片放在JLABEL中显示
.
.
.
Graphics2D g=image.createGraphics();
g.drawString("为啥不好用呢",0,0);
g.dispose();大概代码就是这样了，所有组件放在一个JFRAME中。无论怎么弄这行字也整不到图片上，劳烦各位大大指条明路吧。

Answer 1

坐标有问题吧
g.drawString("为啥不好用呢",0,0);0，0划在一个点了

Answer 2

改了一下还是不行，图片的大小时81*159
改成了g.drawString("为啥不好用呢",50,100);还是不好用。。

Answer 3

BufferedImage image=ImageIO.read(new File(fileName));//读取图片
.
.
.
Graphics2D g=image.createGraphics();
g.drawString("为啥不好用呢",0,0);
g.dispose();
JLabel jl=new JLabel(new ImageIcon(image)); //把图片放在JLABEL中显示----------------这样你试试!

Answer 4

还是不好用……哭了
