![在投影机的讲义模式下可以为单个帧激活覆盖吗?](https://linux22.com/image/427463/%E5%9C%A8%E6%8A%95%E5%BD%B1%E6%9C%BA%E7%9A%84%E8%AE%B2%E4%B9%89%E6%A8%A1%E5%BC%8F%E4%B8%8B%E5%8F%AF%E4%BB%A5%E4%B8%BA%E5%8D%95%E4%B8%AA%E5%B8%A7%E6%BF%80%E6%B4%BB%E8%A6%86%E7%9B%96%E5%90%97%EF%BC%9F.png)
我正在处理一个长投影仪文档,每个框架都有很多叠加层。为了加快我的工作流程,我使用了handout
模式。但是,有时当我处理一个框架时,我想测试叠加层是否正常工作。我很好奇是否可以在handout
模式下为单个框架激活叠加层。
以下是 MWE:
\documentclass[handout]{beamer}
\begin{document}
\begin{frame}
\frametitle{Happy Without Overlays Here}
\begin{block}{First Block}<+->
Foo bar.
\end{block}
\begin{block}{Second Block}<+->
Foo bar.
\end{block}
\end{frame}
\begin{frame}[?magic?]
\frametitle{I Want Overlays Here}
\begin{block}{First Block}<+->
Foo \pause bar.
\end{block}
\begin{block}{Second Block}<+->
Spam \pause eggs.
\end{block}
\end{frame}
\begin{frame}
\frametitle{Also Happy Without Overlays Here}
\begin{block}{First Block}<+->
Foo bar.
\end{block}
\begin{block}{Second Block}<+->
Foo bar.
\end{block}
\end{frame}
\end{document}

您可以暂时切换到其他模式:
\documentclass[
handout
]{beamer}
\begin{document}
\begin{frame}
\frametitle{Happy Without Overlays Here}
\begin{block}{First Block}<+->
Foo bar.
\end{block}
\begin{block}{Second Block}<+->
Foo bar.
\end{block}
\end{frame}
\makeatletter
\gdef\beamer@currentmode{beamer}
\makeatother
\begin{frame}
\frametitle{I Want Overlays Here}
\begin{block}{First Block}<+->
Foo \uncover<+->{bar.}
\end{block}
\begin{block}{Second Block}<+->
Spam \uncover<+->{eggs.}
\end{block}
\end{frame}
\makeatletter
\gdef\beamer@currentmode{handout}
\makeatother
\begin{frame}
\frametitle{Also Happy Without Overlays Here}
\begin{block}{First Block}<+->
Foo bar.
\end{block}
\begin{block}{Second Block}<+->
Foo bar.
\end{block}
\end{frame}
\end{document}
