![\midchapskip 回忆录章节样式中的间距](https://linux22.com/image/434077/%5Cmidchapskip%20%E5%9B%9E%E5%BF%86%E5%BD%95%E7%AB%A0%E8%8A%82%E6%A0%B7%E5%BC%8F%E4%B8%AD%E7%9A%84%E9%97%B4%E8%B7%9D.png)
我正在使用回忆录类创建自定义章节样式。它的定义如下:
\makechapterstyle{balloon}{%
\renewcommand{\chapterheadstart}{\vspace*{\beforechapskip}}
\renewcommand{\printchaptername}{\begin{center} \chapnamefont \chaptername}
\renewcommand{\chapternamenum}{\space}
\renewcommand{\printchapternum}{\chapnumfont \thechapter \end{center}}
\renewcommand{\afterchapternum}{\par\vskip \midchapskip }
\renewcommand{\printchaptertitle}[1]{\chaptitlefont %
\begin{center}%
\MakeUppercase{##1}%
\end{center}}
\renewcommand{\afterchaptertitle}{\par\vskip \afterchapskip}%
\renewcommand{\chapnamefont}{\normalfont\Large}
\renewcommand{\chapnumfont}{\normalfont\Large}
\renewcommand{\chaptitlefont}{\normalfont\scriptsize}%
\setlength{\beforechapskip}{-25pt}
\setlength{\midchapskip}{10pt} % <-- Value in question.
\setlength{\afterchapskip}{7pt}
}
\chapterstyle{balloon}
......
\chapter{The End of a much-applauded Speech -- The Presentation of Dr. Samuel Ferguson -- Excelsior -- Full-length Portrait of the Doctor -- A Fatalist convinced -- A Dinner at the Travellers’ Club -- Several Toasts for the Occasion}
我意识到其中的一些声明\makechapterstyle
是多余的,当我完成样式工作后它们将被删除。
我面临的问题是,更改的值\midchapskip
会对标题的格式产生不一致的影响。此值应控制章节文本(例如“第 1 章”)和章节标题(例如“备受赞誉的演讲结束...”)之间的间距。
负值\midchapskip
对间距完全没有影响,正值则有零星影响。例如,\midchapskip
设置为 20pt 和 10pt 时,实际间距有 10pt 的差异,但设置为 10pt 和 0pt 时,实际间距没有差异。这是为什么?如何精确调整此间距?
TL;DR:为什么我的章节风格没有\midchapskip
达到预期的效果?
答案1
center
您在重新定义\printchaptertitle
---时使用了环境\centering
,而改用了。因此,拼写错误更少
\renewcommand{\printchaptertitle}[1]{\chaptitlefont%
{\centering \MakeUppercase{##1} \par}}
下面显示了将 更改为\printchaptertitle
与 一起的结果\setlength{\midchapskip}{-75pt}
,因此\midchapskip
负值确实会产生影响,就像任何其他值一样。
\begin{center}
也许有人可以解释与的间距差异\centering
。

Here's an MWE with four different `\midchapskip` values to show their effects.
