使用 beamerdefs.sty 在标题上插入背景壁纸

Question

我有一个.tex使用beamerdefs.sty文件的文件。我现在想在标题页上（仅）添加背景图片，但问题是，开始文档部分开始得较晚，如果我尝试在 tex 文件或文件中插入它，beamerdefs.sty它就不会出现。我\usepackage{wallpaper}已经添加了，这里是代码：

% Type of the document

% Change the pictures here:

% Pictures must be supplied as JPEG, PNG or, to be preferred, PDF
\pgfdeclareimage[height=3cm]{logobig}{hulogo}
% Supply the correct logo for your class and change the file name to "logo". The logo will appear in the lower
% right corner:
\pgfdeclareimage[height=0.7cm]{logosmall}{logo}

% Title page outline:
% use this number to modify the scaling of the headline on title page
\renewcommand{\titlescale}{1.0}
% the title page has two columns, the following two values determine the percentage each one should get
\renewcommand{\titlescale}{1.5}
\renewcommand{\leftcol}{0.6}

% Define the title.Don't forget to insert an abbreviation instead 
% of "title for footer". It will appear in the lower left corner:
\title[title]{title}
% Define the authors:
\authora{Author\footnote[1]{footnote}} % a-c
\authorb{}
\authorc{}

% Define any internet addresses, if you want to display them on the title page:
\def\linka{}
\def\linkb{}
\def\linkc{}
% Define the institute:


\institute{\textbf{School of Business and Economics}\\
 \vskip1em

insert here\\
Chairholder: professor\\
Supervisors: another one\\
\vskip1em

% Comment the following command, if you don't want, that the pdf file starts in full screen mode:
\hypersetup{pdfpagemode=FullScreen}

%Start of the document
\begin{document}

% create the title slide, layout controlled in beamerdefs.sty and the foregoing specifications
\frame[plain]{

因此这里是 beamerdefs.sty 文件：

那么我必须插入哪里\TileWallPaper{<width>}{<height>}{<filename>}才能使其工作？

非常感谢你的帮助！

您可以在包含壁纸background canvas的框架之前设置模板 \maketitle，然后再次设置模板以\ClearWallPaper从您不希望它再出现的点清除壁纸：

\documentclass{beamer}
\usepackage{wallpaper}

\title{The Title}
\author{The Author}
\institute{The Institute}

\begin{document}

\setbeamertemplate{background canvas}{\TileWallPaper{.25\paperwidth}{.25\paperheight}{ctanlion}}
\begin{frame}
\maketitle
\end{frame}

\setbeamertemplate{background canvas}{\ClearWallPaper}
\begin{frame}
test
\end{frame}

\end{document}
