int[] buf = new int[img.getWidth(null) * img.getHeight(null)];
PixelGrabber grab = new PixelGrabber(img, 0, 0, img.getWidth(null), img.getHeight(null),
buf, 0, img.getWidth(null));
try {
grab.grabPixels();
} catch (InterruptedException e) {
}
BufferedImage bg = new BufferedImage(img.getWidth(null), img.getHeight(null),
BufferedImage.TYPE_INT_ARGB);
bg.setRGB(0, 0, bg.getWidth(), bg.getHeight(), buf, 0, bg.getWidth());
でＯＫ　（img　→　bg）
