拇指索引部分

Question

我发现这脚本，但无法调整部分内容。以下是我目前得到的结果：

\documentclass{book}
\usepackage{background}
\usetikzlibrary{calc}
\usepackage{ifthen}
\usepackage{lipsum}

\pagestyle{plain}

% background common settings
\SetBgScale{1}
\SetBgAngle{0}
\SetBgOpacity{1}
\SetBgContents{}

% auxiliary counter
\newcounter{partshift}
\addtocounter{partshift}{-1}

\definecolor{mp}{RGB}{240,240,240}

\let\Oldpart\part
\newcommand{\parttitle}{}
\renewcommand{\part}[1]{\Oldpart{#1}\pf\renewcommand{\parttitle}{#1}}

% the main command; the mandatory argument sets the color of the vertical box
\makeatletter
\newcommand\pf{%
\AddEverypageHook{%
\ifthenelse{\isodd{\thepage}}
{\SetBgContents{%
  \begin{tikzpicture}[overlay,remember picture]
  \node[fill=mp,inner sep=0pt,rectangle,text width=2cm,
    text height=4cm,align=center,anchor=north east] 
  at ($ (current page.north east) + (-0cm,-2*\thepartshift cm) $) 
  {\rotatebox{90}{\hspace*{.3cm}\parbox[c][1.5cm][t]{3.4cm}{%
    \raggedright\textcolor{black}{\parttitle}}}};
  \end{tikzpicture}}%
}
{\SetBgContents{%
  \begin{tikzpicture}[overlay,remember picture]
  \node[fill=mp,inner sep=0pt,rectangle,text width=2cm,
    text height=4cm,align=center,anchor=north west] 
  at ($ (current page.north west) + (-0cm,-2*\thepartshift cm) $) 
  {\rotatebox{90}{\hspace*{.3cm}\parbox[c][1.5cm][t]{3.4cm}{%
    \raggedright\textcolor{black}{\parttitle}}}};
  \end{tikzpicture}}
}
\bg@material}%
  \stepcounter{partshift}
}
\makeatother

更新

以下代码已更新，以使用新的语法background。更新后的语法由 Gonzalo Medina 提供，以替换我最初引用的代码这个答案. 查看评论了解历史。

我不确定如何直接修改代码，因为它\part的工作原理与我理解的有点不同\chapter。但是，可以将 Gonzalo Medina 的代码的部分内容与修改后的代码结合起来，以book.cls实现类似的效果：

\documentclass{book}
\usepackage[scale=1,angle=0,opacity=1]{background}
\usetikzlibrary{calc}
\usepackage{ifthen}
\usepackage{lipsum}

\backgroundsetup{contents={}}

\pagestyle{plain}

% auxiliary counter
\newcounter{partshift}
\addtocounter{partshift}{-1}

\definecolor{mp}{RGB}{240,240,240}

\newcommand{\parttitle}{}
\makeatletter
\def\@part[#1]#2{%
    \renewcommand\parttitle{#1}%
    \ifnum \c@secnumdepth >-2\relax
      \refstepcounter{part}%
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%
    \else
      \addcontentsline{toc}{part}{#1}%
    \fi
    \markboth{}{}%
    {\pf%
      \centering
     \interlinepenalty \@M
     \normalfont
     \ifnum \c@secnumdepth >-2\relax
       \huge\bfseries \partname\nobreakspace\thepart
       \par
       \vskip 20\p@
     \fi
     \Huge \bfseries #2\par}%
    \@endpart}
\makeatother
