您好我正在处理一些代码，其中图像将被压缩并将评论从旧图像传输到新压缩图像。压缩工作顺利，但新图像中的评论传输不起作用，并且没有显示在图像的属性 - >评论中。

我还使用 [pyexiv2] https://github.com/LeoHsiao1/pyexiv2进行元数据读写

在第一次运行时它工作正常，但在以后的运行中，评论不再显示在图像属性 -> 评论中。我试过查看代码，也许我只是不小心编辑了一些东西，但似乎并非如此。

import glob2
from PIL import Image, ImageDraw, ImageFont
import os
import pyexiv2


def getImgPaths():
    image_paths = glob2.glob('images/**/*.jpg')
    return image_paths

# ? copy metadata from original to new
def moveMetaData(base_image, new_image):

    print('***** Moving meta-data *****')

    i = pyexiv2.Image(base_image)

    meta_comment = i.read_exif()

    # ? print comment
    print("initial metacomment   : " + meta_comment["Exif.Photo.UserComment"]) 


    # ! encode comment to new image
    new_image_encode = pyexiv2.Image(new_image)
    #  print("New Image Initial Tags: " + str(new_image_encode))

    new_image_encode.modify_exif(
        {"Exif.Photo.UserComment": meta_comment["Exif.Photo.UserComment"]}) 


    o = new_image_encode.read_exif()

    print("Inserted Comment to new image   : " + o["Exif.Photo.UserComment"]) 


def compressImage(image_path):
    im = Image.open(image_path)
    image_name = os.path.basename(os.path.normpath(image_path))
    print('Input file size   : ', im.size)
    print('Input file name   : ', image_name)
    print('Input Image Size  : ', os.path.getsize(image_path))

    out_parent_dir = os.path.join('out', image_path.split(image_name)[0])
    print(out_parent_dir)

    newpath = os.path.join('out', image_path)

    if not os.path.exists(out_parent_dir):
        os.makedirs(out_parent_dir)

    im.save(os.path.join(out_parent_dir, image_name),
            optimize=True, quality=50)

    print('Success ' + image_path)

    # ? copy metadata to new image
    moveMetaData(image_path, newpath)



print('***** Compression Started *****')

for image_path in getImgPaths():
    try:
        compressImage(image_path)
    except Exception as e:
        print(e)
        with open('logs/errors.txt', 'a') as fh:
            print(str(e) + " : " + str(image_path), file=fh)
        pass


print('***** Compression Ended *****')
