以下是使用背景图像的解决方案的草图:
\documentclass[11pt]{beamer}
\usepackage{graphicx}
%Global Background must be put in preamble
\usebackgroundtemplate%
{%
% to scale the image such that it fills the entire slide
\includegraphics[width=\paperwidth,height=\paperheight]{ARlys.png}%
% alternative: scale the image such that the it fits best into the
% slide without changing the aspect ratio
%\includegraphics[width=\paperwidth,height=\paperheight,keepaspectratio]{ARlys.png}%
}
\begin{document}
\begin{frame}%{First slide}
This is the content of the first slide
\end{frame}
\begin{frame}%{Second slide}
This is the content of the second slide
\end{frame}
\end{document}
您应该根据自己的规格调整背景图像。给定的图像如下所示:
如果您希望只为特定框架设置背景图像,只需将整个开始-结束框架块包裹在花括号中即可。您可以在中间插入命令。{
然后,这只会对花括号内的框架产生局部作用。\begin{frame}
\usebackgroundtemplate{...}
这应该足以让你明白了;)
