You may try this. 你可以试试这个。
// Get the icon
Icon ico = label1.getIcon();
// Create a buffered image
BufferedImage bimg = new BufferedImage(ico.getIconWidth(), ico.getIconHeight(),
BufferedImage.TYPE_INT_RGB);
// Create the graphics context
Graphics g = bimg.createGraphics();
// Now paint the icon
ico.paintIcon(null, g, 0, 0);
g.dispose();

由于JLabel.getIcon()返回一个Icon，因此你想将Icon转换为bufferedImage。我认为你需要查看这个问题。你可以通过这种方式将图标转换为BufferedImage
