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?

问题描述

我一直在尝试检查已知包含IPTC数据的JPEG文件，但无论如何都不会注意到任何字符串。我尝试了众所周知的UNIX 字符串命令，ASCII，8位，16位Unicode ---无济于事：我看不到任何我希望在IPTC领域找到的字符串。

I have been trying to examine a JPEG file, known to contain IPTC data, but could notice no strings whatsoever. 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.

我的问题是：IPTC数据是如何编码的？它加密了吗？压缩？其他？为什么不能使用字符串命令查看？

My question is: How is IPTC data encoded? Is it encrypted? Compressed? Other? Why can't it be viewed using the strings command?

推荐答案

使用十六进制查看器无法查看IPTC数据的最可能原因是因为它没有IPTC数据。

The most probable reason why you cannot view IPTC data using a hex viewer is because it has no IPTC data.

包含IPTC数据的图像，如下所示：

An image that contains IPTC data like this one:

有一个XML结构和文本字段，可以通过像Emacs这样的文本编辑器查看（8-位，甚至不是Unicode）。

has an XML structure and text fields that are view-able through a text editor like Emacs (8-bit, not even Unicode).
