        // leaving bits 3-4 untouched. This is very similar to the swap
        // image from your programming assignment. The code shown here is
        // for one pixel, of course you would have to put this code inside
        // a nested loop to process an entire image. Remember that bit 0
        // is the least significant and bit 7 is the most significant.
        
        // For example, oldPixel = 0b11010011 would transform to newPixel = 0b11010110
