在Canvas上显示图片的问题
重载的paint函数如下

public void paint(g)
{
        ...
        g.drawImage(img,0,0,mimp.getWidth(),mimp.getHeight(),
                    0,0,mimp.getWidth(),mimp.getHeight(),this);
        ...
}

现在想在画好的图上再显示一张
public void paint(g)
{
        ...//img和anotherImg均为Image类型
        g.drawImage(img,0,0,mimp.getWidth(),mimp.getHeight(),
                    0,0,mimp.getWidth(),mimp.getHeight(),this);
        ...
        if(anotherImg!=null&&.../*其它条件*/)
       {
            Graphics g1=g.create();
            javax.swing.JOptionPane.showMessageDialog(null,"要画了");
            //弹出一句话
            g1.drawImage(anotherImg,0,0,this);
       }
       ...
}


第二张图片打死我也出不来(图片格式均为JPG)
哪里不对，是不是paint函数里不能有两个drawImage
各位高HIGHHAND请指示，解决后另开贴给HI分

public void paint(Graphics g) {
                          ~~~~
    ...
    Graphics g1=g.create();
            ~~~~
    ...
    g1.drawImage(anotherImg,0,0,this);
   ~~~~
    ...
}

您这是往哪儿画呐？

载入图片并清空原来的图象
public void paint(g)
{
        java.awt.MediaTracker mt=new java.awt.MediaTracker(this);
        mt.addImage(img,0);
        mt.addImage(anotherImg,0);
        try{mt.waitForAll();}catch(Exception e){}
        ...//img和anotherImg均为Image类型
        g.drawImage(img,0,0,mimp.getWidth(),mimp.getHeight(),
                    0,0,mimp.getWidth(),mimp.getHeight(),this);
        ...
        if(anotherImg!=null&&.../*其它条件*/)
       {
            javax.swing.JOptionPane.showMessageDialog(null,"要画了");
            //弹出一句话
            g.clearRect(0,0,this.getWidth(),this.getHeight());
            g.drawImage(anotherImg,0,0,this);
       }
       ...
}
