从Beamer页脚中删除幻灯片计数

Question

我想SLIDE_NUMBER / TOTAL_SLIDES从Beamer演示文稿的页脚(footline)中删除幻灯片计数(例如),而不是完全删除页脚.我正在使用Boadilla主题,它使用infolines外部主题.在beamerouterthemeinfolines.sty文件中,我们找到了以下脚线的定义:

\defbeamertemplate*{footline}{infolines theme}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor~~(\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,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
  \end{beamercolorbox}}%
  \vskip0pt%
}

我需要基本上重新定义这个外部主题,使其没有内部主题\insertframenumber{} / \inserttotalframenumber\hspace*{2ex},或者以其他方式定义一个新的外部主题,继承infolines主题中的所有其他主题.我怎样才能做到这一点？

Answer 1

由于beameroutertheminfolines.sty自2010年以来已经改变,现在它足以把

\setbeamertemplate{page number in head/foot}{}

在序言中.

如果你愿意,你可以简单地改变文件beameroutertheminfolines.sty,这可能不是一个好主意.因此,您只需将脚线的代码放入.tex文件中并删除帧编号的行,或者像我一样,将其转换为注释.因此,您将确切的部分复制beameroutertheminfolines.sty到.tex文件中:

 \documentclass{beamer}
    %#comment out the Boadilla theme and uses only the header bar
    %\usetheme[]{Boadilla} 
    \usetheme[secheader]{Boadilla}

      %#make sure to change this part, since it is predefined
      %\defbeamertemplate*{footline}{infolines theme}
      \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~~(\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,right]{date in head/foot}%
        \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}

    %#turning the next line into a comment, erases the frame numbers
        %\insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 

      \end{beamercolorbox}}%
      \vskip0pt%
    }
