如何在單字上打叉號？

我想知道 LaTeX 中是否存在可以在單字上打十字標記的命令？

答案1

在 TikZ （和函式庫）的幫助下shapes，可以製作一些漂亮的劃掉效果。

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes}

\newcommand{\crossme}[2][]{%


\tikz[baseline=(X.base)]{\node [outer sep=0pt,cross out,draw=#1,line width=2pt] (X) {#2};}%
}


\begin{document}
A nice \crossme[blue]{crossed} word.
\end{document}

只是為了完整性：\xcancel從cancel包中也可以。

\documentclass{beamer}
\usepackage{cancel}
\begin{document}
\begin{frame}
\frametitle{Crossing out words}
\begin{overlayarea}{\textwidth}{\textheight}
No more \xcancel{alcohol}. No more
\textcolor{red}{\xcancel{\textcolor{black}{fast food}}}.
\end{overlayarea}
\end{frame}
\end{document}

更新：真的只是為了好玩：一個可以使用換行符（但不能使用分頁符號！）並且不會引入額外空格的版本。基於這個答案。

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{tikzpagenodes}
\usepackage{ulem}
\newcommand\HighLight{\bgroup\markoverwith{\textcolor{yellow}{\rule[-.5ex]{.1pt}{2.5ex}}}\ULon}

\tikzset{StrikeOut/.style={thick,-}}

可以透過調整來自訂線路的屬性StrikeOut。
