pixels[2] = c.getRed() ;
l3.add(c.getRed());
raster2.setPixel(xx, yy, pixels);}
}
}
}
in above code i am giving three different plane (red plane,green plane,blue plane)that each plane reading pixel by pixel .i am storing each pixel in array list according to that image color . i want retrieve original image by using three different plane .is it possible and in above code if i add three array list in one image is it found original image please help me how form by using three different plane into one image

It seems to be a repost. Why don't you just edit your original question here instead of posting a new question on the same problem each and every day?

Move your ImageIO.write outside of your loop.
Currently you're creating a new image file for every row of pixels in the source file.

Change

Java

for (int xx = 0; xx < width; xx++) {
   for (int yy = 0; yy < height; yy++) {
      Color c = new Color(image.getRGB(xx, yy));
      int[] pixels = raster.getPixel(xx, yy, (int[]) null);
      {
         pixels[0] = c.getRed() +50;
         pixels[1] = c.getGreen();
         pixels[2] = c.getBlue() + 50;
         raster.setPixel(xx, yy, pixels);
      }
      ImageIO.write(image, "png",new File("200.png"));
   }
}

to

Java

for (int xx = 0; xx < width; xx++) {
   for (int yy = 0; yy < height; yy++) {
      Color c = new Color(image.getRGB(xx, yy));
      int[] pixels = raster.getPixel(xx, yy, (int[]) null);
      {
         pixels[0] = c.getRed() +50;
         pixels[1] = c.getGreen();
         pixels[2] = c.getBlue() + 50;
         raster.setPixel(xx, yy, pixels);
      }
   }
}
ImageIO.write(image, "png",new File("200.png"));

Hope this helps,
Fredrik
