问题描述

如何使我的图像全尺寸而不仅仅放大中心？

我的图像名为1-12.jpg。

How do I make my images full size and not just zoomed in on the center?
My images are named 1-12.jpg.

这是我的代码：

import java.awt.*;
import javax.swing.*;
import javax.swing.border.BevelBorder;
public class GuiApp extends JFrame{

  public static void main(String [] args){

     final JFrame shirts = new JFrame("T-shirts");

        JPanel panel = new JPanel(new GridLayout(4, 4, 3, 3));

        for (int i = 1; i < 13; i++) {
            JLabel l = new JLabel(new ImageIcon("T-shirts/"+i+".jpg"), JLabel.CENTER);
            l.setBorder(BorderFactory.createBevelBorder(BevelBorder.RAISED));
            l.setFont(l.getFont().deriveFont(20f));
            panel.add(l);
        }//end of for loop

        shirts.setContentPane(panel);
        shirts.setSize(1000, 1000);
        shirts.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        shirts.setVisible(true);

  }//end of method
}//end of class

由此我假设您的意思是如何缩小图像以使其完全显示在网格上的可用空间中？

By this I assume you mean how do you shrink the image so that it is completely displayed in the space available on the grid?

查看拉伸图标（或 ShrinkIcon 取决于哪个更符合您的要求）。随着标签大小的变化，此图标将动态调整大小。 StretchIcon 允许您按比例缩放图标（默认）或填充可用空间。

Check out Stretch Icon (or ShrinkIcon depending on which meets your requirement better). This icon will dynamically resize as the size of the label changes. The StretchIcon allows you to scale the icon proportionally(default) or to fill the available space.

由于 GridLayout 使所有组件的大小相同，图标的大小也相同。

Since a GridLayout makes all components the same size the icons will also be the same size.

基本代码应为：

//JLabel l = new JLabel(new ImageIcon("T-shirts/"+i+".jpg"), JLabel.CENTER);
StretchIcon icon = new StretchIcon("T-shirts/"+i+".jpg");
JLabel l = new JLabel(icon, JLabel.CENTER);
