How to convert JLabel.getIcon() to BufferedImage

Question

I have a JLabel that contains only an icon, and I can get the Icon with label1.getIcon(), but I can't figure out how to convert that Icon into a BufferedImage. Just FYI, I'm not talking about ImageIcon, only Icon. Also, I have seen the question at How to convert Icon from JLabel into BufferedImage?, but I can't seem to figure it out.

As always, any examples or explanation are much appreciated. Thanks!

JLabel label1 = new JLabel();....and then it is added to an array of JLabels, but that doesn't really matter. — iphonedev7, Jan 09 '13 at 04:50
"but I can't seem to figure it out." what confuses you in AndrewThompson's answer in the question you have specified? — Nikolay Kuznetsov, Jan 09 '13 at 04:52
*"but that doesn't really matter."* Yes it does, or at least it might. Since you apparently have no idea how to do this, it would pay not to jump to conclusions about what is/is not necessary or relevant. For better help sooner, post an [SSCCE](http://sscce.org/). — Andrew Thompson, Jan 09 '13 at 04:52
@NikolayKuznetsov I did exactly what AndrewThompson described, but it didn't work...I'm really not sure why. — iphonedev7, Jan 09 '13 at 04:54
I think you need to see [this question](http://stackoverflow.com/questions/5830533/how-can-i-convert-an-icon-to-an-image) — Freak, Jan 09 '13 at 04:56

You may try this.

// 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();

As JLabel.getIcon() returns a Icon so you want to convert the Icon to bufferedImage.I think you need to view this question.Here you can get the way through which you can convert a icon to BufferedImage
