这个问题是根据给出的解决方案代码构建的这里。我想知道如何像这样添加章节缩略图：
代码：
\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{tikz}
\usepackage{lipsum}
\usepackage{xcolor}
\usepackage{geometry}

\usetikzlibrary{calc}
\definecolor{ultramarine}{RGB}{0,45,97}
\definecolor{mybluei}{RGB}{0,173,239}
\definecolor{line}{RGB}{70,160,216}
\definecolor{fillh}{RGB}{225,233,251}
\renewcommand{\headrulewidth}{0pt}
\newcommand\hdheight{1in}

只需在代码中添加 5 行（标记为%%%% <--- !）即可将缩略图标记添加到输出中。对于标记的宽度/高度、标记中的文本大小等，您需要设置拇指包。请查看其手册和示例文件。
