我正在尝试输入一个新命令，使某些文本居中、加粗并将文本颜色设为红色。以下是我通过修改和查看已有的代码得出的结果：
\newcommand{\rub}{\large\bfseries\fontfamily{pbk}\selectfont\color{red}\filcenter}
我制定了新的命令\rub，到目前为止一切可以正常工作，只是花括号内的文本未居中。我该如何通过新命令修复以使其居中？
我确实尝试了以下操作：
{\newcommand{\rub}{\large\bfseries\fontfamily{pbk}\selectfont\color{red}\filcenter}{}{0em}{#1}
但出现错误：
You can't use `macro parameter character #' in horizontal mode. ...\selectfont\color{red}\filcenter}{}{0em}{#
但我不太确定这意味着什么。

答案1
抓住提供的参数\rub并将其设置在宽度为的居中框内\linewidth：
\newcommand{\rub}[1]{\noindent\makebox[\linewidth]{\large\bfseries\fontfamily{pbk}\selectfont\color{red}#1}}
这是一个最小的例子（没有字体会发生变化，因为它不是讨论的一部分）：

\usepackage{xcolor}
\usepackage{indentfirst}
\usepackage[explicit]{titlesec}
\titleformat{\chapter}
{\normalfont\LARGE\bfseries\filcenter}{}{0em}{#1}
\titleformat{\section}

\titleformat{\subsection}
{\normalfont\Large\bfseries\filcenter}{}{0em}{#1}
\newcommand{\scrip}[1]{{\Large #1}}
\newcommand{\rub}[1]{\noindent\makebox[\linewidth]{\large\bfseries\color{red}#1}}

答案2
\newcommand*\rub[1]
{\begin{center}\large\bfseries\color{red}\fontfamily{pbk}\selectfont#1\end{center}}
...
\rub{This text will be centered, boldfaced, colored red and with font `pbk'}
但由于您没有说要用它做什么，我们不知道是否有更精确和正确的方法。
答案3
这是你想要的吗？
\documentclass[a4paper,12pt]{report}
\usepackage{titlesec}
\usepackage{xcolor}
\begin{document}
\newcommand{\rub}{\large\bfseries\fontfamily{pbk}\selectfont\color{red}\filcenter}
\rub Mytext
\end{document}
如果您想使用 as \rub{only inside here will be affected}，那么：
\newcommand{\rub}[1]{\large\bfseries\fontfamily{pbk}\selectfont\color{red}\filcenter{#1}}
答案4
这是一个不使用center环境的解决方案，它增加了不必要的垂直空间。
