我有一个在 beamer 中突出显示文本的定义，它是从这里的一些帖子中获得的。当我使用beamer类时，它工作正常，但当我使用类时，它会抱怨定义standalone。这是一个外部定义的文件，\input当我使用独立类生成一些 PDF 图时，我需要该文件内容中的其他定义。所以，如果我能解决这个问题会很有帮助。有人知道为什么定义在类中失败了吗standalone？这是一个有效的 MWE：
\documentclass[margin=1mm,xcolor=pdftex,dvipsnames]{beamer}
\usepackage{tikz}
%---This is for highlighting text on overlays ----
\usepackage{xcolor,soul}
\sethlcolor{yellow}
\renewcommand<>{\hl}[1]{\only#2{\beameroriginal{\hl}}{#1}}
\makeatletter
\newcommand\SoulColor{%
\let\set@color\beamerorig@set@color
\let\reset@color\beamerorig@reset@color}
\makeatother
\SoulColor
\begin{document}
\frame{\hl{Test}
}
\end{document}
但是，当我转换为时beamer，standalone它会给我错误：
