![数学颜色也适用于 \text{} 和 \intertext{}](https://linux22.com/image/478488/%E6%95%B0%E5%AD%A6%E9%A2%9C%E8%89%B2%E4%B9%9F%E9%80%82%E7%94%A8%E4%BA%8E%20%5Ctext%7B%7D%20%E5%92%8C%20%5Cintertext%7B%7D.png)
我有一个 LaTeX 投影仪演示文稿,我用它\setbeamercolor{math text}
来增强可读性,效果很好。不幸的是,所有\text{}
内容\intertext{}
都是彩色的,看起来不太好看。有什么补救措施吗?
梅威瑟:
\documentclass{beamer}
\usepackage{xcolor}
\usepackage{amsmath}
\setbeamercolor{math text}{fg=blue}
\begin{document}
\begin{frame}
This is a term in math mode: $a^2 + b^2 = c^2$.
This is color inside of \texttt{align*}, but the text is colored as well:
\begin{align*}
a^2 + b^2 = c^2 && \text{(Pythagoras)}. \\
\intertext{Even worse, the intertext is colored as well:}
a^1 + b^1 = c^1 && \text{(me)}.
\end{align*}
\end{frame}
\end{document}
它产生以下输出:
更新:@Mico 提供了一个很好的解决方案,效果很好,甚至适用于 inline-math \intertext
,但它也会为表格着色!可以避免吗?
另外,\text
确实切换回黑色,但数学\text
保持黑色。看看\text
里面$x$
的\underbrace
。
以下是更新的 MWE:
\documentclass{beamer}
%\setbeamercolor{math text}{fg=blue}
%\newcommand\blackintertext[1]{\intertext{\textcolor{black}{#1}}}
\everymath=\expandafter{\the\everymath\color{blue}}
\let\origtext\text
\renewcommand\text[1]{\origtext{\textcolor{black}{#1}}}
\begin{document}
\begin{frame}
This is a term in inline-math mode: $1+1=2$.
Displayed equations are colored as well \dots
\begin{align*}
\underbrace{a^2 + b^2}_{\text{magic $x$}} &= c^2 \tag{Pythagoras} \\
\intertext{\dots\ but, happily, intertext material is no longer colored. Even $\pi \approx 3.14$ is colored.}
e^{i\pi} + 1 &= 0 \tag{Euler}
\end{align*}
\begin{tabular}{l|l}
What & about \\
\hline
a & table?
\end{tabular}
\end{frame}
\end{document}

我建议你更换
\setbeamercolor{math text}{fg=blue}
和
\everymath=\expandafter{\the\everymath\color{blue}}
此外,要排版方程式“标签”,请使用\tag
宏。
为了“修复”宏的行为\text
,即使它以黑色输出其参数,我建议您在序言中添加以下两个指令:
\let\origtext\text
\renewcommand\text[1]{\origtext{\textcolor{black}{#1}}}
以下是生成如上所示截图的代码:
\documentclass{beamer}
%\setbeamercolor{math text}{fg=blue}
\everymath=\expandafter{\the\everymath\color{blue}}
\begin{document}
\begin{frame}
This is a term in inline-math mode: $1+1=2$.
Displayed equations are colored as well \dots
\begin{gather*}
a^2 + b^2 = c^2 \tag{Pythagoras} \\
\intertext{\dots\ but, happily, intertext material is no longer colored.}
e^{i\pi} + 1 = 0 \tag{Euler}
\end{gather*}
\end{frame}
\end{document}
