Beamer：所有框架上的相同图形具有相同的图形编号

Question

当同一幅图像在多个帧上使用时，是否可以获得相同的图号？（不介意手动更改图号）谢谢

Answer 1

至少有两个相对简单的选项：beamer 的\againframe（第 11.2 节）手册）， 或者操作数字计数器：

\documentclass{beamer}
\setbeamertemplate{caption}[numbered]

\begin{document}

\begin{frame}[label=A]
The original frame
\begin{figure}
\centering
\includegraphics[width=0.5\textwidth]{example-image-a}
\caption{\label{fig:example}Caption}
\end{figure}
\end{frame}

\begin{frame}
A second frame
\begin{figure}
\centering
\includegraphics[width=0.5\textwidth]{example-image-b}
\caption{Caption}
\end{figure}
\end{frame}

\againframe{A}

\begin{frame}
A third frame
\begin{figure}
\centering
\includegraphics[width=0.5\textwidth]{example-image-c}
\caption{Caption}
\end{figure}
\end{frame}

\begin{frame}
A slightly different frame with a repeated image from the first frame

\includegraphics[width=0.5\textwidth]{example-image-a}
\renewcommand\thefigure{1}
\caption{Caption}
\addtocounter{figure}{-1}
\end{figure}
\end{frame}

\begin{frame}
A fourth frame
\begin{figure}
\centering
\includegraphics[width=0.5\textwidth]{example-image-b}
\caption{Caption}
\end{figure}
\end{frame}

\end{document}
