调整JButton中的ImageIcon大小 [英] resizing a ImageIcon in a JButton

问题描述

我正在创建一个包含特定ImageIcon的JButton。主要问题是原始图标大小比按钮大小大得多。结果显示按钮时，只能看到部分图标。什么是调整ImageIcon以使其适合JButton的方法？

I am creating a JButton which includes a specific ImageIcon. The main issue is that the original icon size is much bigger than the button size. As result when the button is displayed, only part of the icon can be seen. What is the method that "resize" an ImageIcon i n order to make it fit inside a JButton?

推荐答案

   Image img = icon.getImage() ;  
   Image newimg = img.getScaledInstance( NEW_WIDTH, NEW_HEIGHT,  java.awt.Image.SCALE_SMOOTH ) ;  
   icon = new ImageIcon( newimg );
