java JLabel 放入的图片 显示不全是怎么回事

jlman=new JLabel(new ImageIcon("d://3.gif"));
this.getContentPane().add(jp);

jp.add(jlman);
jlman.setBounds(333,333,128,128);
manx=333;
many=333;
jp.addMouseListener(
new MouseAdapter(){
public void mouseClicked(MouseEvent e){
myx=e.getX();
myy=e.getY();
}
}
);
this.setSize(800,600);
this.setVisible(true);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}是不是什么地方要设置不对呢？？

Answer 1

应该是 label 太小
给你介绍个 方法
希望对你有帮助

剪裁图像

private ImageIcon scaleImage(ImageIcon icon) {
int width = icon.getIconWidth();
int height = icon.getIconHeight();

if (width = 80 && height = 80) {
return icon;
}
Image image = icon.getImage();
image = image.getScaledInstance(80, 80, Image.SCALE_DEFAULT);

return new ImageIcon(image);
}

Answer 2

import javax.swing.*;
import java.awt.*;
import java.applet.*;
public class Welcome extends JApplet
{
JPanel panel;
JLabel logoImagePosition;
public Welcome(){}
public void init()
{

panel=new JPanel();
Icon logoImage=new ImageIcon("Pig.gif");
logoImagePosition=new JLabel(logoImage);
panel.add(logoImagePosition);
this.getContentPane().add(panel);
}
}
参考一下吧

是不是图片比你的label要大？调整一下你的label的大小试试~
