python - 使用 Python 检索图像描述(不通过 PIL 或 exifread 在 EXIF 数据中返回)

Question

我想获取 .jpg 图像的描述。它显示在 Mac OSx 信息 (cmd +i) 窗口中。

我想阅读“描述”(德语为 Beschreibung)字段。用 PIL 和 exifread 尝试这个没有成功。

我可以获得这些 exif 标签，但它们不包含描述或关键字。

我假设这些字段不是 EXIF 数据？我需要寻找什么才能获得描述？

Answer 1

感谢@Mark Serchells 的回答，我发现描述不是EXIF 数据而是IPTC 数据(exiftool 显示所有字段)。

在 Python 中，我现在可以使用 IPTCInfo3:https://pypi.org/project/IPTCInfo3/并通过以下方式提取描述:

info = IPTCInfo('img.jpg')
info['caption/abstract']
