python - 如何使用 Python 在 Windows 7 文件资源管理器中访问和更改 JPEG 图像的标签描述属性？

Question

我很难理解如何通过 Python 更改 JPEG 文件的标签。我指的“标签”是指任何任意文件的描述属性下的标签，其中还可以找到评论、主题和评级。我不确定是否有类似于文件名重命名功能的 .os 功能可以执行此操作，或者这种更改标签的操作是否属于 JPEG 元数据/EXIFDATA 操作的类别。

例如，我想通过 Python 向 JPEG 图像添加 3 个标签，即标签 BLUE、SQUARE 和 9。我会手动转到文件，通过右键单击文件查看其标签，或单击底部栏菜单，然后单击标签，然后在文本框中输入 BLUE、SQUARE 和 9，每个单独的标签后有一个分号。使用 Python 时，我需要一个脚本来将这些单独的标签注入(inject)到 JPEG 的描述属性中，以便在我为多个 JPEG 文件迭代执行此操作时减少痛苦。

我怀疑这是否需要任何熟练的 Python 编程知识，但与此同时，我的问题的特殊性似乎无法轻松解决。我似乎无法找到一个半明确或直接的答案，因为在使用 python 进行一般编程时我有点新手。

任何帮助都会非常非常有用。我正在使用 Python 3.5.2。顺便说一下。

Answer 1

所以，这是我修改后的答案。 因此，jpg 中的所有信息都是用“id”编号存储的元数据，例如第 0 是您要查找的描述区域，这里是一个表。

0th:
283 = (720000, 10000)
296 = 2
34665 = 11444
306 = b'2011:08:22 21:39:05'
270 = b''
271 = b'OLYMPUS IMAGING CORP.'
272 = b'E-P1'
305 = b'Adobe Photoshop CS5 Windows'
274 = 1
33432 = b'Robin Parmar'
282 = (720000, 10000)
315 = b'Robin Parmar'

所以要像主题一样改变你需要做的就是......

pip install piexif

这适用于 2.7 和 3

import piexif

def insert_sample():
    zeroth_ifd = {270: "test"}
    exif_bytes = piexif.dump({"0th":zeroth_ifd})
    piexif.insert(exif_bytes,'img.jpg')

insert_sample() 

希望对您有所帮助 :D 这是所有 ID 的列表
