抓取图像像素到int数组

    int w=im.getWidth(this);
    int h=im.getHeight(this);
    int[] pixels=new int[w*h];

    public int[] Image2intAarry(Image im){
        try{
            PixelGrabber pg=new PixelGrabber(im,0,0,w,h,pixels,0,w);
            pg.grabPixels();
        }catch(InterruptedException e){
            e.printStackTrace();
        }
        return pixels;
    }
