resize给文件重新命名和大小

下面的代码是一个文件夹中的所有文件重新命名并改变大小

from PIL import Image

from PIL import ImageTk

import os

path1 = '/home/python/Desktop/zz/bad/'

path2 = '/home/python/Desktop/zz/input_data_resized/'

#path2 = './input_data/'

pictures = []

for root, dirs, files in os.walk(path1):

    for f in files:

        pictures.append(os.path.join(root,f))

src = "0"

i=0

lenth= len(src)

print(lenth)

for dir in pictures:

#duqu meizhang tupian

    im = Image.open(dir)

#shengcheng 000001 000002 ...

    s = src[0:(lenth-len(str(i)))] + str(i+2950)

    width,high = im.size

#chongxin shezhi tupian daxiao

    if width > high:

        out = im.resize((200, 256), Image.ANTIALIAS)

    else:

        out = im.resize((200, 256), Image.ANTIALIAS)

    out.save(path2+s+'.jpeg')

    i = i+1
