[JAVA2D] Black&White Picture!

[Armond Avanes]

Hi Friends,

I want to make a Black&White image from a colored one (the format is JPG)
using Java2D!
Well, I'm using these lines of code to do it :

        private ImageIcon prepareBnWImage(Image img, ImageObserver io)
        {
        int iw = img.getWidth(io);
        int ih = img.getHeight(io);
        BufferedImage srcImg = new BufferedImage(iw, ih,
BufferedImage.TYPE_INT_RGB);
        Graphics2D srcG = srcImg.createGraphics();
        RenderingHints rhs = srcG.getRenderingHints();

                srcG.setRenderingHints(rhs);
                srcG.drawImage(img, 0, 0, null);

        ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
        ColorConvertOp theOp = new ColorConvertOp(cs, rhs);
        BufferedImage dstImg = new BufferedImage(iw, ih,
BufferedImage.TYPE_INT_RGB);

                theOp.filter(srcImg, dstImg);
                return( new ImageIcon(dstImg) );
        }

Everything works great but the problem is that the picture has "transparent"
background. When I convert it to B&W pic, the background turns to BLACK and
gets very ugly! I want the background to remain transparent as it was.

Any solution ? Idea? Comment ?

Best Regards,
Armond
