是否可以在十六进制查看器中查看IPTC数据？

[英]Is it possible to view IPTC data in a hex-viewer?

I have been trying to examine a JPEG file, known to contain IPTC data, but could notice no strings whatsoever. 我一直在尝试检查一个已知包含IPTC数据的JPEG文件，但是可能不会注意到任何字符串。 I tried the well known UNIX strings command, ASCII, 8-bit, 16-bit Unicode --- to no avail: I could not see any strings that I expect to find in IPTC fields. 我尝试了众所周知的UNIX 字符串命令，即ASCII，8位，16位Unicode ---无济于事：我看不到我希望在IPTC字段中找到的任何字符串。

My question is: How is IPTC data encoded? 我的问题是：IPTC数据如何编码？ Is it encrypted? 加密了吗？ Compressed? 压缩？ Other? 其他？ Why can't it be viewed using the strings command? 为什么不能使用strings命令查看它？

The most probable reason why you cannot view IPTC data using a hex viewer is because it has no IPTC data. 无法使用十六进制查看器查看IPTC数据的最可能原因是因为它没有IPTC数据。

An image that contains IPTC data like this one: 包含IPTC数据的图像，如下所示：

has an XML structure and text fields that are view-able through a text editor like Emacs (8-bit, not even Unicode). 具有XML结构和可通过诸如Emacs（8位，甚至不是Unicode）之类的文本编辑器查看的文本字段。
