我正在尝试将背景图像添加到 Beamer Talk 的标题页。我尝试使用此处提供的解决方案仅使用 Beamer 在标题页上创建背景图像。但是我遇到了一些我不明白的问题。这是我的 MWE。
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package (or none)
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font
\usepackage{tikz}
\usefonttheme[onlylarge]{structurebold}
\setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries}
\setbeamertemplate{navigation symbols}{}
\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{normal text}{fg=white}
\pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410}
\setbeamertemplate{title page}{
\begin{picture}(0,0)
\put(-30,-163){%
\pgfuseimage{mybackground}
}
\put(0,-110.7){%
\begin{minipage}[b][45mm][t]{226mm}
\usebeamerfont{title}{\inserttitle\par}
\end{minipage}
}
\end{picture}
}
\title{Lost in data}
\author[Author et al.\@]{Author}
\institute{University of }
\date{}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\end{document}
我的问题是
- 标题未居中
- 标题页上未显示作者和机构
如果我注释掉 libertine 字体行，我会得到
LaTeX 字体警告：字体形状“T1/cmss/m/n”的大小 <4> 不可用（字体）大小 <5> 在输入行 44 上替换。
（我似乎可以使用 \usepackage{lmodern} 解决最后一个问题，但我不确定我是否喜欢该字体。）
非常感谢您的帮助。

如果您想要做的只是在标题页的背景中添加图像，那么链接答案中描述的方法并不是最合适的方法，因为设置模板title page需要设置模板的所有元素及其属性（这是您的问题的一部分（见下文））。
更方便的方法是在本地（组内）设置模板background canvas：
\documentclass{beamer}
\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{normal text}{fg=white}
\setbeamercolor{title}{fg=white}
\title{The title}
\author{The Author}
\institute{The Institute}
\begin{document}
\begingroup
\setbeamertemplate{background canvas}{%
\includegraphics[width=\paperwidth,height=\paperheight]{mushrooms}}
\begin{frame}
\maketitle
\end{frame}
\endgroup
\begin{frame}
test
\end{frame}
\end{document}
但是，如果您想通过从头开始设置模板来彻底更改标题页模板，那么：
您的标题未居中，因为您当前的设置没有告诉 LaTeX 您希望它居中；事实上，
minipage您使用的标题太大了，您可以通过暂时禁用颜色并为其设置框架来看到这一点：\documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{libertine} % or any other font package (or none) \newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font \usepackage{tikz} \usefonttheme[onlylarge]{structurebold} \setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries} \setbeamertemplate{navigation symbols}{} %\setbeamercolor{background canvas}{bg=black} %\setbeamercolor{normal text}{fg=white} \pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410} \setbeamertemplate{title page}{ \begin{picture}(0,0) \put(-30,-163){% % \pgfuseimage{mybackground} } \put(0,-110.7){% \centering \frame{\begin{minipage}[b][45mm][t]{226mm} \centering \usebeamerfont{title}{\inserttitle\par} \end{minipage}} } \end{picture} } \title{Lost in data} \author[Author et al.\@]{Author} \institute{University of } \date{} \begin{document} \begin{frame} \titlepage \end{frame} \end{document}
更改
226mm为并在 内部\textwidth使用：\centeringminipage\documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{libertine} % or any other font package (or none) \newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font \usepackage{tikz} \usefonttheme[onlylarge]{structurebold} \setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries} \setbeamertemplate{navigation symbols}{} %\setbeamercolor{background canvas}{bg=black} %\setbeamercolor{normal text}{fg=white} \pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410} \setbeamertemplate{title page}{ \begin{picture}(0,0) \put(-30,-163){% % \pgfuseimage{mybackground} } \put(0,-110.7){% \frame{\begin{minipage}[b][45mm][t]{\textwidth} \centering \usebeamerfont{title}{\inserttitle\par} \end{minipage}} } \end{picture} } \title{Lost in data} \author[Author et al.\@]{Author} \institute{University of } \date{} \begin{document} \begin{frame} \titlepage \end{frame} \end{document}
也许您还想降低高度？
由于您对标题页模板的设置没有相应的插入内容，因此没有标题或机构；您希望此信息出现在哪里？在所需位置使用
\insertauthor。\insertinstitution例如：\documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{libertine} % or any other font package (or none) \newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font \usepackage{tikz} \usefonttheme[onlylarge]{structurebold} \setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries} \setbeamertemplate{navigation symbols}{} \setbeamercolor{background canvas}{bg=black} \setbeamercolor{normal text}{fg=white} \pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410} \setbeamertemplate{title page}{ \begin{picture}(0,0) \put(-30,-163){% \pgfuseimage{mybackground} } \put(0,-110.7){% \frame{\begin{minipage}[b][45mm][t]{\textwidth} \centering \usebeamerfont{title}{\inserttitle\par}\vfill \usebeamerfont{author}{\insertauthor\par}\vfill \usebeamerfont{institute}{\insertinstitute\par} \end{minipage}} } \end{picture} } \title{Lost in data} \author[Author et al.\@]{Author} \institute{University of } \date{} \begin{document} \begin{frame} \titlepage \end{frame} \end{document}
对设置满意后，删除（或注释掉）命令
\frame：\documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{libertine} % or any other font package (or none) \newcommand*\quotefont{\fontfamily{LinuxLibertineT-TLF}} % selects Libertine for quote font \usepackage{tikz} \usefonttheme[onlylarge]{structurebold} \setbeamerfont*{frametitle}{size=\normalsize,series=\bfseries} \setbeamertemplate{navigation symbols}{} \setbeamercolor{background canvas}{bg=black} \setbeamercolor{normal text}{fg=white} \pgfdeclareimage[width=\paperwidth]{mybackground}{bigdata410} \setbeamertemplate{title page}{ \begin{picture}(0,0) \put(-30,-163){% \pgfuseimage{mybackground} } \put(0,-110.7){% \begin{minipage}[b][45mm][t]{\textwidth} \centering \usebeamerfont{title}{\inserttitle\par}\vfill \usebeamerfont{author}{\insertauthor\par}\vfill \usebeamerfont{institute}{\insertinstitute\par} \end{minipage}% } \end{picture} } \title{Lost in data} \author[Author et al.\@]{Author} \institute{University of } \date{} \begin{document} \begin{frame} \titlepage \end{frame} \end{document}
有多种方法可以解决此警告；加载包含缺失字体大小的字体（
lmodern例如）或使用\let\Tiny\tiny。
