一次显示一张图像

Question

我在一张幻灯片中排列了四张图片，我想一次显示一张图片。

我能够使用下面的代码显示文本

\begin{frame}
\frametitle{Table of Contents}
\begin{itemize}
\item<1-> Introduction
\item<2-> Algorithm for reducing finite automata
\item<3-> Reliability models
\item<4-> Reduction steps
\item<5-> References
\item<6-> Conclusion
\end{itemize}
\end{frame}

我想以同样的方式展示图像。

我已经将图像对齐如下

\begin{frame}
\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc5.jpg}}
\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc6.jpg}}
\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc8.jpg}}
\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc7.jpg}}
\end{frame}

Answer 1

也许与\alt和\phantom，假设你使用了自定义定义\vcenteredhbox，我发现这里。

\documentclass{beamer}
\usepackage{graphicx}

\newcommand*{\vcenteredhbox}[1]{\begingroup
\setbox0=\hbox{#1}\parbox{\wd0}{\box0}\endgroup}


\newcommand{\thepic}{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pic.png}}

\begin{document}


\begin{frame}
 \vcenteredhbox{\thepic}
 \vcenteredhbox{\alt<2->{\thepic}{\phantom{\thepic}}}
 \vcenteredhbox{\alt<3->{\thepic}{\phantom{\thepic}}}
 \vcenteredhbox{\alt<4->{\thepic}{\phantom{\thepic}}}
\end{frame}

\end{document}

Answer 2

或许就uncover足够了。

\documentclass[demo]{beamer}

\newcommand*{\vcenteredhbox}[1]{#1}

\begin{document}


\begin{frame}
\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc5.jpg}}
\uncover<2->{\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc6.jpg}}}
\uncover<3->{\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc8.jpg}}}
\uncover<4->{\vcenteredhbox{\includegraphics[width=5cm,height=5cm,keepaspectratio]{pc7.jpg}}}
\end{frame}

\end{document}
