The function mirrorHalf (Program 47) mirrors the top half of the picture onto the bottom half.

def mirrorHalf(picture): pixels = getPixels(picture) target = len(pixels) - 1 for index in range(0,len(pixels)/2): pixel1 = pixels[index] color1 = getColor(pixel1) pixel2 = pixels[target] setColor(pixel2,color1) target = target - 1

Write a new function mirrorUpHalf that mirrors the bottom half of the picture into the top.
