您能告诉我是否可以自动将章节缩略图的彩色框中的文本置于中央吗？
此外，如何使代码以这样的方式运行，即章节缩略图框和文本仅显示在页面的右侧而不是交替显示？
答案1
要将文本置于拇指框的中心，只需修改以下与命令相关的代码片段\SetBgContents：
{\SetBgContents{%
\begin{tikzpicture}[overlay,remember picture]
\node[fill=\BoxColor,inner sep=0pt,rectangle,text width=1cm,
text height=4cm,align=center,anchor=north east]
at ($ (current page.north east) + (-0cm,-2*\thechapshift cm) $)
{\rotatebox{90}{\parbox{4cm}{%
\centering\textcolor{black}{\scshape\leftmark}}}};
\end{tikzpicture}}%
}
{\SetBgContents{%
\begin{tikzpicture}[overlay,remember picture]
\node[fill=\BoxColor,inner sep=0pt,rectangle,text width=1cm,
text height=4cm,align=center,anchor=north west]
at ($ (current page.north west) + (-0cm,-2*\thechapshift cm) $)
{\rotatebox{90}{\parbox{4cm}{%
\centering\textcolor{black}{\scshape\leftmark}}}};
\end{tikzpicture}}
}
如你所见，修改的部分是：
\hspace*{.8cm}应被删除。- 对齐方式
\raggedright应更改为\centering。 \parbox[c][.3cm][t]{3.4cm}应该更改为，因为您已经在节点选项中将\parbox{4cm}文本宽度（在text height旋转之前提到）设置为。4cm[..., text height=4cm, ...]
