python實現圖片批量剪裁的程序

from PIL import Image
import os
fin = 'D:/test'
fout = 'D:/test2'
for file in os.listdir(fin):
    file_fullname = fin + '/' +file
    img = Image.open(file_fullname)
    a = [80, 100, 260, 300]
    box = (a)
    roi = img.crop(box)
    if fout not in os.listdir('D:/'):
        os.mkdir(fout)
    out_path = fout + '/' + file
    roi.save(out_path)

基礎不好，花樣踩坑，在此記錄一下。
