环境：
windows10
python 3.7
Pillow库
使用 pip install Pillow 安装
1. 先在文件浏览器中输入 %localappdata%PackagesMicrosoft.Windows.ContentDeliveryManager_cw5n1h2txyewyLocalStateAssets 然后拷贝实际地址，替换python中 TARGET_PATH 对应部分；
2. 把下面的python代码脚本和批处理脚本放在同一个目录下，双击批处理就可以看到锁屏照片；
3. python程序中通过 MIN_IMAGE_W 和 MIN_IMAGE_H 来设定最小的图片分辨率，可根据实际情况修改；
python 源码：
add_extend.py
#!/usr/bin/python
# -*- coding: UTF-8 -*-
__author__ = 'ppdyhappy'
import os
import shutil
from PIL import Image
TARGET_PATH = r'use your own file path here!'
MIN_FILE_SIZE = 300*1024
MIN_IMAGE_W = 1920
MIN_IMAGE_H = 1080
def do_add_extend(path, cur_file_name_list):
for _, _, filenameArr in os.walk(TARGET_PATH):
for name in filenameArr:
file_path = os.path.join(TARGET_PATH, name)
if os.path.getsize(file_path) <= MIN_FILE_SIZE:
continue
if name + '.jpg' in cur_file_name_list:
continue
w, h = Image.open(file_path).size
if w < MIN_IMAGE_W or h < MIN_IMAGE_H:
continue
new_file_path = os.path.join(path, name + '.jpg')
shutil.copy(file_path, new_file_path)
def get_cur_jpg_file_list(path):
temp_list = []
for _, _, filenameArr in os.walk(path):
for name in filenameArr:
if name.endswith('.jpg'):
# print(name)
temp_list.append(name)
return temp_list
def add_extend():
cur_path = os.getcwd()
cur_jpg_file_list = get_cur_jpg_file_list(cur_path)
do_add_extend(cur_path, cur_jpg_file_list)
if __name__ == '__main__':
add_extend()
print('Done')
批处理内容：
python ./add_extend.py
效果：
