Black background when scaling images with transparent background

Question

I am implementing Zooming functionality for reports which have some icons. I am trying to scale icon by scaling its image. But the problem I am facing is that the icons have transparent background and the scaling puts a black background in place of transparent. Is there any way to maintain its transparency or better yet, Is there anyway to put a white backgound instead of the black one that is created by default ? Here is my code
     public static Icon getScaledIcon(Icon icon){
         if(icon instanceof ImageIcon){
              Image outImage = ((ImageIcon)icon).getImage();
                  return new ImageIcon(getScaledImage(outImage));
         }else{
              Image outImage = new BufferedImage(icon.getIconWidth(),
                        icon.getIconHeight(),
                        BufferedImage.TYPE_INT_ARGB);
                JComponent comp = new JComponent(){};
                icon.paintIcon(comp, outImage.getGraphics(), 0, 0);
                return new ImageIcon(getScaledImage(outImage));
    public static Image getScaledImage(Image image){
         image = image.getScaledInstance((int)(image.getWidth(null) * getScale()),
                       (int)(image.getHeight(null) * getScale()), Image.SCALE_SMOOTH);
        return image;
    }I haven't done much image manipulation , so I would really appreciate any help or advice.

I have also not done much of image work. But I guess you could achieve your functionality of showing scaled image in the screen by not scaling the image and show it, instead scale the image in paint method by calling g.drawImage giving the height and width. But use high resolution images so that scaling is good.
If you do in this manner, you could give any colour you want as background to fill the transparent area or leave it as such.
