由於雲盤空間有限，照片尺寸也是很大，所以寫個Python程式壓縮一下照片，騰出一些雲盤空間

1、批量壓縮照片

新建 photo_compress.py 程式碼如下

執行python .\photo_compress.py F:\\test

生成compress_output資料夾，裡面就是壓縮的檔案，但此時的照片沒有，拍攝時的時間、位置的資訊，所以下面要複製檔案資訊

若要壓縮的檔案不全，可以再執行一次壓縮（會自動過濾已壓縮的照片）

2、批量拷貝照片資訊

使用pyexiv2進行檔案資訊拷貝

pip install pyexiv2 -i https://pypi.tuna.tsinghua.edu.cn/simple

新建 copy_fileinfo.py 程式碼如下

# -*- coding: utf-8 -*-

"""指令碼功能說明：使用 pyexiv2 api，一鍵批量拷貝指定檔案(夾)所有檔案資訊"""

import os
import sys
from concurrent.futures import ThreadPoolExecutor,ProcessPoolExecutor # 執行緒池，程序池

def get_file_dir(file):
 """獲取檔案目錄通用函式"""
 fullpath = os.path.abspath(os.path.realpath(file))
 return os.path.dirname(fullpath)


def check_suffix(file_path):
 """檢查指定檔案的字尾是否符合要求"""
 file_path_lower = file_path.lower()
 return (file_path_lower.endswith('.png')
   or file_path_lower.endswith('.jpg')
   or file_path_lower.endswith('.jpeg'))


def copyinfo_by_pyexiv2(input_file):
 file_name = os.path.basename(input_file)
 arr = file_name.split('.')
 new_file_name = arr[len(arr) - 2] + '_compress.' + arr[len(arr) - 1]
 output_path = os.path.join(get_file_dir(input_file),new_file_name)
 if not (check_suffix(input_file) or check_suffix(output_file)):
  print(u'只支援png\\jpg\\jepg格式檔案：' + input_file)
  return
 if not (os.path.exists(output_file)):
  print(u'檔案不存在：' + output_file)
  return
 old_size = os.path.getsize(input_file)
 if (old_size < 1024 * 1024):
  print(u"已跳過拷貝檔案資訊：",input_file)
  return

 # if not os.path.isdir(output_path):
 #  os.makedirs(output_path)
 try:
  i = Image(input_file) # 源圖片路徑
 except Exception:
  i = Image(input_file,"GB18030")

 try:
  _exif_info = i.read_exif()
 except Exception:
  _exif_info = i.read_exif("GB18030")

 # print(_exif_info)
 # _iptc_info = i.read_iptc()
 # print(_iptc_info)
 # _xmp_info = i.read_xmp()
 # print(_xmp_info)
 i.close()

 try:
  i2 = Image(output_file) # 拷貝資訊圖片路徑
 except Exception:
  i2 = Image(output_file,"GB18030")

 try:
  _exif_info2 = i2.read_exif()
 except Exception:
  _exif_info2 = i2.read_exif("GB18030")

 # 方向不拷貝，防止圖片旋轉
 for item in _exif_info:
  if("Exif.Image.Orientation" != item):
   if (_exif_info2.get(item) != _exif_info.get(item)):
    try:
     i2.modify_exif({item: _exif_info[item]})
    except Exception as e:
     print(e)
     try:
      i2.modify_exif({item: _exif_info[item]},"GB18030")
     except Exception as e:
      print(e)

 i2.close()

 print(u"拷貝資訊完成：" + input_file)


def check_path(input_path):
 """如果輸入的是檔案則直接壓縮，如果是資料夾則先遍歷"""
 if os.path.isfile(input_path):
  copyinfo_by_pyexiv2(input_path)
 elif os.path.isdir(input_path):
  dirlist = os.walk(input_path)
  for root,files in dirlist:
   if (not (root.endswith("\\compress_output") or root.endswith("/compress_output"))):
    i = 0
    for filename in files:
     i = i + 1
     process_pool.submit(copyinfo_by_pyexiv2,filename))
 else:
  print(u'目標檔案(夾)不存在，請確認後重試。')


if __name__ == '__main__':
 # thread_pool = ThreadPoolExecutor(10) # 定義5個執行緒執行此任務
 process_pool = ProcessPoolExecutor(8) # 定義5個程序
 len_param = len(sys.argv)
 if len_param != 2:
  print('請使用： %s [filepath]' % os.path.basename(sys.argv[0]))
 else:
  check_path(sys.argv[1])
  input("Press <enter> 請耐心等待\n")
