投影機：圖上有氣泡/包含 pdf（中）

Question

我試圖包含一個pdf文檔，我想在中間添加氣泡/註釋框架，這是我的程式碼的一部分（因為項目太長）（正在使用beamer）：基本上它工作正常，但當我想要看到它們，我想把它們放在我加入的每個pdf的中間，這樣就很容易看到問題。 已編輯 整個專案的連結

如果將影像包含在TikZ節點內，則可以將其用作標註節點的參考（帶有remember picture和選項）。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: 回覆mirette評論。

您的程式碼是正確的，結果是預期的。tikzmark建立對其位置的引用，在您的情況下，該位置位於includegraphics命令之後，並mycallout根據此引用放置，在本例中，該引用位於所包含圖形的左下角下方。

建議的解決方案會替換tikzmark為node包含整個頁面的 ，然後您可以使用頁面上的任何位置來放置標註。

由於mycallout命令已在tikzpicture環境內定義，因此最好在為包含的頁面定義的 tikzpicture 之外使用它。

以下程式碼顯示了一個框架上有兩個圖形的範例。兩個數字均已使用 Beamercolumns環境進行分發。
