考虑一下代码
\documentclass[openany]{book}
\usepackage{scalefnt}
\usepackage{lipsum}
\usepackage{color}
\begin{document}
\thispagestyle{empty}
\LARGE
\lipsum[19]
\vspace*{20pt}
\begin{center}
\begin{minipage}{4.00in}
\textbf{\scalefont{0.75}{\color{red}{THIS IS A MINIPAGE ENVIRONMENT IN WHICH THE FONTSIZE HAS BEEN SCALED DOWN---BUT THE SPACING BETWEEN THE LINES SEEMS TO HAVE BEEN UNAFFECTED}}---I WOULD LIKE TO REDUCE THE VERTICAL SPACE BETWEEN THE LINES PROPORTIONATELY.}
\end{minipage}
\end{center}
\end{document}
产生输出
尽管 minipage 环境中的文本似乎已按 0.75 倍缩放，但行之间的垂直间距却没有缩放。（为了更清楚地看到这一点，请尝试按 0.15 倍缩放）。
问题：如何按比例调整缩放的小页面环境中的垂直间距，以使其反映对文本施加的缩放比例？
谢谢。
答案1
与往常一样，段落中使用的行距是段落末尾有效的行距，因此如果您想要设置的基线间距，\scalefont您需要（就像您使用过一样\small）在其范围内结束段落。
