Wave filter. Write a filter like those in the previous two exercises that creates a wave effect, by copying the color of each pixel (si, sj) in the source image to a target pixel (ti, tj), where ti = si and tj = sj + 20 sin(2 π sj / 64). Add code to take the amplitude (20 in the accompanying figure) and the frequency (64 in the accompanying figure) as command-line arguments. Experiment with various values of these parameters.
