                        (int) Math.round((i * BitmapWidth) / 100),
                        (int) Math.round((j * BitmapHeight) / 100));

                //Get RGB code
                pixelSumRed += Color.red(pixel);

        int AverageColorCodeRGB = Color.rgb(averagePixelRed + 3,
                averagePixelGreen + 3, averagePixelBlue + 3);
