我试图包含一个 pdf 文档，并且我想在中间添加气泡/注释框，这是我的代码的一部分（因为项目太长）（正在使用 beamer）：基本上它工作正常，但是当我想看到它们时却不行，我想把它们放在每个 pdf 的中间，我加入了一个图，这样就很容易看到问题了。

如果将图像包含在TikZ节点内，则可以将其用作标注节点的参考（带有remember picture和选项）。overlay
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{shapes.callouts, calc}
\begin{document}
\begin{frame}
\centering
\begin{tikzpicture}[remember picture, overlay]
\node (a) {\includegraphics[width=.75\linewidth]{example-image-a}};
\node<2->[ellipse callout, draw=blue, fill=blue!30] at ($(a.center)!.5!(a.north east)$) (b) {Hello!};
\end{tikzpicture}
\end{frame}
\end{document}
更新：回答mirette评论。
您的代码是正确的，结果也是预期的。tikzmark创建对其位置的引用，在您的情况下是在includegraphics命令之后，并mycallout根据此引用放置，在本例中，位于所包含图形的左下角下方。
提出的解决方案是tikzmark用node包含整个页面的 来替换，然后您可以使用页面上的任何位置来放置标注。
由于mycallout命令已在tikzpicture环境中定义，因此最好在包含页面定义的 tikzpicture 之外使用它。
columns下面的代码展示了一个帧上有两幅图的例子。两幅图都使用 beamer环境进行分发。
