遗憾的是，我无法从另一个有同样问题的问题中获得我需要的帮助：
未定义控制序列 \draw 和 \end{tikzpicture}
我正在使用这个答案中提供的代码：https://tex.stackexchange.com/a/25433/61740我的目标是显示图像的选定部分并放大它们。我使用的代码与那里介绍的完全一样（缩放框就是从那里来的）。
我的代码如下：

但是，它运行完美，但却给我留下了Undefined control sequence \end{tikzpicture}错误消息，但没有\draw与相关问题相关的内容。此错误消息来自使用 Kile 进行编译。
使用 pdflatex 编译时出现以下消息：
! Undefined control sequence.
\tikz@atend@picture ...r sep=0pt] \{\subcaptionbox
{\label {\pgfkeysvalueof {...
l.422 \end{tikzpicture}
如果subcaptionbox没有注释掉该包，则会出现以下错误：
! Package subcaption Error: This package can't be used in cooperation
(subcaption) with the subfig package.
