使用 eso-pic 包:
\documentclass{article}
\usepackage{lipsum}
\usepackage{graphicx}
\usepackage{eso-pic}
\begin{document}
\AddToShipoutPictureBG*{\includegraphics[height=\paperheight]{example-image}}
\lipsum
\end{document}
使用 tikz 包:
\documentclass{article}
\usepackage{lipsum}
\usepackage{graphicx}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[remember picture, overlay]
\node at (current page.center) {\includegraphics[height=\paperheight]{example-image}};
\end{tikzpicture}
\lipsum
\end{document}
编辑:将图像放置在其自己的页面上而不是背景中:
\documentclass{article}
\usepackage{lipsum}
\usepackage{graphicx}
\usepackage{tikz}
\begin{document}
\lipsum[2]
\clearpage
\begin{tikzpicture}[remember picture, overlay]
\node at (current page.center) {\includegraphics[height=\paperheight]{example-image}};
\end{tikzpicture}
\clearpage
\lipsum[2]
\end{document}
或者使用 pdfpages:
\documentclass{article}
\usepackage{lipsum}
\usepackage{pdfpages}
\begin{document}
\lipsum[2]
\includepdf[height=\paperheight]{example-image}
\lipsum[2]
\end{document}
