python图像处理入门

1.转换成灰度图片

from PIL import Image
Image.open('in.jpg').convert('L').save('out.jpg');

一行代码搞定，是不是很酷~

2.图形复制与粘贴

from PIL import Image
import os

pil_im = Image.open('in.png');
box = (0,162,30,192)
box2 = (200,162,230,192)
region = pil_im.crop(box)
pil_im.paste(region,box2)
pil_im.save('out.png')
