下面的方法也许能帮你入门。只需example-image
用按钮的图片文件替换即可:
\documentclass{article}
\usepackage{blindtext} % just for dummy contents
\usepackage{tikz}
\usepackage{eso-pic}
\usepackage{hyperref}
\begin{document}
\AddToShipoutPicture{%
\begin{tikzpicture}[remember picture,overlay]
\node [rectangle, anchor=center, yshift=2cm]
(box\thepage) at
(current page.south){\hyperlink{mytableofcontents}{\includegraphics[width=1cm]{example-image}}};
\end{tikzpicture}}
\phantomsection
\hypertarget{mytableofcontents}{}
\tableofcontents
\blinddocument
\end{document}
