Rainbow fileter
1.卡點：怎麼在Y方向，做分割沽瘦，然後在每一等份中革骨，做出紅橙黃綠藍靛紫的區(qū)別农尖，並且向X方向展開，我在Conditional Execution 的 4:49找到概念良哲，然後這裡盛卡，先不貪多，只先實驗紅色（1/7 塊）筑凫，看可不可以成功窟扑，之後再展開。
- Start with the image you want to change.
- Figure out the width of the image.
- For each pixel in the image:
Get the x-coordinate for that pixel
If the pixel’s x-coordinate is less than one-third of the image’s width, set the pixel’s red value to 255.
If the pixel’s x-coordinate is between one-third and two-thirds of the image’s width, set the pixel’s green value to 255.
If the pixel’s x-coordinate is more than two-thirds of the image’s width, set the pixel’s blue value to 255.
- Print the image.
2.如果成功展開漏健，就把miniproject-challenge 提供的彩虹濾鏡的code
嚎货，一一填上。
