Java padding image

Presumably, you want to create a new image from an existing image, where the new image has white space on the left and right?

Suppose the unpadded image was a BufferedImage and is called 'image'. Suppose the amount of whitespace you want on each side is 'w'. What you want to do is create a new BufferedImage wider than the original, then paint the entire thing white, and finally draw the smaller image on top of it:

BufferedImage newImage = new BufferedImage(image.getWidth() + 2 * w, image.getHeight(), image.getType());

Graphics g = newImage.getGraphics();

g.setColor(Color.white);
g.fillRect(0, 0, image.getWidth() + 2 * w, image.getHeight());
g.drawImage(image, w, 0, null);
g.dispose();

If anyone comes upon a similar problem, I would definitively recommend imgScalr. You can add padding with literally one line imageSource= Scalr.pad(imageSource,pad,Color.White);.
