      BufferedImage bi=new BufferedImage(1024,1024,BufferedImage.TYPE_INT_RGB);
     
      for(int i=0; i<1024; i++)
         for(int j=0; j<1024; j++)
         {
            int col=FastNoise.noise(i/128f, j/128f, 7);
           
            int red=col;
            int green=col;
            int blue=col;
           
            int RGB=red;
            RGB=(RGB<<8)+green;
            RGB=(RGB<<8)+blue;
           
            bi.setRGB(i, j, RGB);
         }
      try {
          File outputfile = new File("noise.png");
          ImageIO.write(bi, "png", outputfile);
      } catch (IOException e) {
          e.printStackTrace();
      }

EDIT: I am using VALUE NOISE, not TRUE GRADIENT here! Cuz I don't know how to get gradient one properly. Cheesy
