用颜色划掉

tag-icon • tag-icon beamer strikeout
用颜色划掉

我的问题涉及：　不同颜色的删除线出现在字母后面，而不是字母上面，只不过我使用的是 beamer 而不是 article。因此，那里提供的解决方案不知何故不起作用。我手头上的例子是：

\PassOptionsToPackage{dvipsnames,svgnames,x11names}{xcolor}
\documentclass[t, 10 pt, mathserif]{beamer}
\usepackage{xparse,soul}

\makeatletter
\NewDocumentCommand{\sotwo}{O{red}O{black}+m}
    {%
        \begingroup
        \setulcolor{#1}%
        \setul{-.5ex}{.4pt}%
        \def\SOUL@uleverysyllable{%
            \rlap{%
                \color{#2}\the\SOUL@syllable
                \SOUL@setkern\SOUL@charkern}%
            \SOUL@ulunderline{%
                \phantom{\the\SOUL@syllable}}%
        }%
        \ul{#3}%
        \endgroup
    }
\makeatother

\begin{document}
Hello \sotwo{Welt} World!

\sotwo[green]{Here is a long sentence that will span across a number of lines to force a linebreak}

\sotwo[green][blue]{Here is a long sentence that will span across a number of lines to force a linebreak}

Here is a long sentence that will span across a number of lines to force a linebreak

\end{document}

任何想法都将不胜感激！谢谢！

在这种情况下，对代码进行简单的更改即可：在 的定义中\setulcolor{#1}%简单地用 替换。\color{#1}%\sotwo

示例输出

\PassOptionsToPackage{dvipsnames,svgnames,x11names}{xcolor}
\documentclass[t, 10pt]{beamer}

\usepackage{xparse,soul}

\makeatletter
\NewDocumentCommand{\sotwo}{O{red}O{black}+m}
    {%
        \begingroup
        \color{#1}%
        \setul{-.5ex}{.4pt}%
        \def\SOUL@uleverysyllable{%
            \rlap{%
                \color{#2}\the\SOUL@syllable
                \SOUL@setkern\SOUL@charkern}%
            \SOUL@ulunderline{%
                \phantom{\the\SOUL@syllable}}%
        }%
        \ul{#3}%
        \endgroup
    }
\makeatother

\begin{document}

of lines to force a linebreak}

\sotwo[green][blue]{Here is a long sentence that will span across a

您也可以从为什么投影机里的灵魂着色不可见：

\makeatletter
\newcommand\SoulColor{%
  \let\set@color\beamerorig@set@color
  \let\reset@color\beamerorig@reset@color}
\makeatother
\SoulColor

得出的结果是：
