花式云引号-算术溢出

Question

我想做一个花哨的引用...（有什么想法吗？）我找不到任何东西，所以我想到使用云...我的代码是

\end{tikzpicture}

\end{frame}%<------------error at that line

\end{document}

问题是，我收到一条错误，指出存在算术溢出。不过，云是 produsecf。所以我的问题与What is this arithmetic overflow和有关Any fancy quotes？

Answer 1

请考虑找出一个最小的例子，因为它会更强调这个问题。这个问题可以简化为以下内容

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{shapes.callouts}
\begin{document}
\begin{frame}
\begin{tikzpicture}
        \node[align=center,
        gray!20, draw,fill, text=red, 
        cloud callout, cloud puffs=20, cloud puff arc=145, callout pointer segments=1, 
        anchor=pointer, callout relative pointer={(0:1 cm )}, aspect=4,
        scale=0.5] 
        at (0,0) 
        {\textbf{\large ``There is something rotten in the state of our detector.''}};
\end{tikzpicture}
\end{frame}
\end{document}

错误的原因在于您将指针段设置为 0，这使其只是一个cloud不是cloud callout或思考气球。因此必须至少有一个段来防止错误。

另外，如前所述，您使用的选项现已过时。编译后查看警告消息。

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{shapes.symbols}
\begin{document}
\begin{frame}
\begin{tikzpicture}
        \node[align=center,gray!20, draw,fill, text=red, 
        cloud, cloud puffs=10, aspect=4,scale=0.5] 
        at (0,0) 
        {\textbf{\large ``There is something rotten in the state of our detector.''}};
\end{tikzpicture}
\end{frame}
\end{document}
