Question

我正在使用 KOMA-Script 制作章节缩略图。我该如何修改它以从目录中删除“0”章节缩略图？

Answer 1

用于\lohead[]{}删除章节缩略图并\loheadwithchapterthumbs{}启用它们。

\documentclass{scrbook}
\usepackage{rotating}
\usepackage{xcolor}
\usepackage{scrpage2}
\usepackage{chapterthumbs}
\usepackage{blindtext}% dummy text
\begin{document}
\lohead[]{}% no chapterthumbs
\tableofcontents
\cleardoublepage
\loheadwithchapterthumbs{}% use chapterthumbs
\blinddocument
\end{document}

但请注意，该包chapterthumbs已经过时，因为它基于已弃用的包scrpage2。

我建议使用chapterthumb可以与一起使用的包scrlayer-scrpage。chapterthumb.sty这是 KOMA-Script 书籍示例的一部分。您可以从https://komascript.de/komascriptbuch5examples. 它位于 zip 文件的“Anhang-B”文件夹中。

\documentclass{scrbook}
\usepackage[ngerman]{babel}
\usepackage{chapterthumb}[2016/02/01]
\usepackage{scrlayer-scrpage}
\pagestyle{scrheadings}
\AddLayersToPageStyle{@everystyle@}{chapterthumb}
\addtokomafont{chapterthumb}{\bfseries}
\renewcommand*{\chapterthumbwidth}{.05\paperheight}
\renewcommand*{\chapterthumbskip}{.05\paperheight}
\renewcommand*{\chapterthumbformat}{\thechapter}

\usepackage{blindtext}% dummy text
\begin{document}
\tableofcontents
\blinddocument
\end{document}

这两个示例也适用于标准类book。

chapterthumb如果您想手动启用或禁用章节缩略图，您可以定义分别向所有图层页面样式添加或删除图层的命令：

\documentclass{scrbook}
\usepackage[ngerman]{babel}
\usepackage{chapterthumb}[2016/02/01]
\usepackage{scrlayer-scrpage}

\addtokomafont{chapterthumb}{\bfseries}
\renewcommand*{\chapterthumbwidth}{.05\paperheight}
\renewcommand*{\chapterthumbskip}{.05\paperheight}
\renewcommand*{\chapterthumbformat}{\thechapter}

\newcommand*\chapterthumbson{%
  \AddLayersToPageStyle{@everystyle@}{chapterthumb}%
}% command to enable chapter thumbs
\newcommand*\chapterthumbsoff{%
  \RemoveLayersFromPageStyle{@everystyle@}{chapterthumb}%
}% command to disable chapter thums
\chapterthumbsoff% disable chapter thumbs
\usepackage{blindtext}% dummy text
\begin{document}
\tableofcontents
\blinddocument

\clearpage
\chapterthumbson% enable chapter thumbs
\blinddocument
\end{document}
