向 Beamer 模板添加元素

Question

我想将包含简短作者/标题/页码的脚注（如 Boadilla 主题中一样）添加到新加坡主题中（基本上，我希望新加坡加上脚注）。我只想在演示文稿中使用它（而不是创建新模板）。我尝试查看文档和网络，但找不到简单的方法。有什么建议吗？谢谢。

Answer 1

主题Boadilla使用外部主题的脚注infolines。您可以将定义复制到演示文稿中并根据需要更改颜色：

\documentclass{beamer}

\author{names}
\title{text}

\usetheme{Singapore}



\makeatletter


\setbeamertemplate{footline}{%
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\ifblank\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,leftskip=2ex,rightskip=2ex,sep=0pt]{date in head/foot}%
    \hfill%
    \usebeamerfont{date in head/foot}%
    \insertshortdate{}%
    \hfill%
    \usebeamercolor[fg]{page number in head/foot}%
    \usebeamerfont{page number in head/foot}%
    \usebeamertemplate{page number in head/foot}%
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother



\setbeamercolor{author in head/foot}{use=structure,fg=black,bg=structure.fg!40!white}
\setbeamercolor{title in head/foot}{use=structure,fg=white,bg=structure.fg!60!white}
\setbeamercolor{date in head/foot}{use=structure,fg=white,bg=structure.fg!90!white}
