投影机中的图形摘要已编辑

Question

我有以下beamer介绍：

\documentclass{beamer}
\setbeamertemplate{navigation symbols}{}
\begin{document}

\section{First}
\begin{frame}[label=A]
\noindent\includegraphics[width=\framewidth]{example-image-a.jpg}
\end{frame}

\section{Second}
\begin{frame}[label=B]
\noindent\includegraphics[width=\framewidth]{example-image-b.jpg}
\end{frame}

\section{Third}
\begin{frame}[label=C]
\noindent\includegraphics[width=\framewidth]{example-image-c.jpg}
\end{frame}

\section{Fourth}
\begin{frame}[label=D]
\noindent\includegraphics[width=\framewidth]{example-image} 
\end{frame}

\begin{frame}
\frametitle{Graphical abstract}

I would like here to have a reduced view of 
frames A, B, C and D on one frame.
\end{frame}
\end{document} 

最后一帧应该是演示的一种图形抽象，即我希望它在一帧中包含帧 A、B、C 和 D 的缩小视图。

我该如何实现这个目标？

根据下面 Sam Carter 的评论，我尝试了以下简单但不合理的解决方案：

\documentclass{beamer}
\setbeamertemplate{navigation symbols}{}
\begin{document}

\section{First}
\begin{frame}[label=A]
\noindent\includegraphics[width=\framewidth]{example-image-a.jpg}
\end{frame}

\section{Second}
\begin{frame}[label=B]
\noindent\includegraphics[width=\framewidth]{example-image-b.jpg}
\end{frame}

\section{Third}
\begin{frame}[label=C]
\noindent\includegraphics[width=\framewidth]{example-image-c.jpg}
\end{frame}

\section{Fourth}
\begin{frame}[label=D]
\noindent\includegraphics[width=\framewidth]{example-image}
\end{frame}

\begin{frame}
\frametitle{Graphical abstract}

I would like here to have a reduced view of frames A, 
B, C and D one one frame.
\end{frame}

\begin{frame}
\scalebox{0.2}{\againframe{A}}\scalebox{0.2}{\againframe{B}}
\end{frame}
\end{document} 

这几乎满足了我的要求，只是 Beamer 在我的缩放帧之间添加了很多垃圾。

有任何类似的想法吗，或者我是否太无赖了beamer。

Answer 1

此代码将前四个框架放入 minipage 中，每个框架使用\againframe。其宽度由 minipage 的宽度控制。请注意，汇编代码为外部一個框塊。
