投影机中图像的某一部分闪烁

我已经使用 tikz 在 latex 中绘制了图像，如下面的代码所示。通过以下代码生成的图像由一个矩形块组成，其中写有文本 E(s)。我想让这个矩形框及其内部的文本闪烁并发出明亮的光芒（闪烁）。我该怎么做？

\documentclass[compress, xcolor=table, usenames,dvipsnames]{beamer}

正如我在评论中所说，beamer 文档有内置的动画制作工具。这里不需要该animate包。如果您编译

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{chains}
\newcount\mymix
\begin{document}

\begin{frame}[t]
\frametitle{A scintillator}
\animate<2-22>
\animatevalue<1-21>{\mymix}{0}{20}
\centering
\begin{tikzpicture}[circ/.style={circle,inner sep=3.2mm,draw},
 box/.style={draw,rounded corners=3pt,minimum width=16mm,minimum height=8mm},
 line width=0.75pt]
 \begin{scope}[start chain=going right,nodes={on chain,join},
    every join/.style={-stealth}]
  \node[circ](C1){};
  \pgfmathtruncatemacro{\mixture}{10*ifthenelse(\the\mymix<11,\the\mymix,20-\the\mymix)}
  \node[box](B1){$\mathsf{C}(\mathsf{s})$};
  \node[box,fill=yellow!\mixture](B2){$\mathsf{P}(\mathsf{s})$};
  \node[circ](C2){};
 \end{scope}
 \path (B2.east) -- coordinate (aux)(C2.west) ;
 \draw[-stealth](aux) --++ (0,-1cm) -| (C1);
\end{tikzpicture}
\end{frame}
\end{document}

并在 Acrobat Reader 上以全屏模式查看，您将看到

在此处输入图片描述

请注意，我利用这个机会缩短了你的 Ti钾Z 代码，我希望我选择了您想要闪烁的矩形。当然，您可以更改动画的细节。您可以使用 更改速率\transduration。

但是，你当然可以使用该animate包。将上述内容转换为使用此包的代码可得出

\documentclass{beamer}
\usepackage{animate}
\usepackage{tikz}
\usetikzlibrary{chains}
\begin{document}

\begin{frame}[t]
\frametitle{A scintillator}
\begin{animateinline}[autoplay,loop]{1}
  \multiframe{20}{it=0+1}{%
    \begin{tikzpicture}[circ/.style={circle,inner sep=3.2mm,draw},
   box/.style={draw,rounded corners=3pt,minimum width=16mm,minimum height=8mm},
   line width=0.75pt]
   \begin{scope}[start chain=going right,nodes={on chain,join},
      every join/.style={-stealth}]
    \node[circ](C1){};
    \pgfmathtruncatemacro{\mixture}{10*ifthenelse(\it<11,\it,20-\it)}
    \node[box](B1){$\mathsf{C}(\mathsf{s})$};
    \node[box,fill=yellow!\mixture](B2){$\mathsf{P}(\mathsf{s})$};
    \node[circ](C2){};
   \end{scope}
   \path (B2.east) -- coordinate (aux)(C2.west) ;
   \draw[-stealth](aux) --++ (0,-1cm) -| (C1);
  \end{tikzpicture}}
\end{animateinline}  
\end{frame}
\end{document}

在这两种情况下，我都不知道您所说的闪烁到底是什么意思，因此您可能需要调整一些参数。
