latex - 从Beamer页脚删除幻灯片计数

Question

我想从Beamer演示文稿的页脚(页脚)中删除幻灯片计数(例如SLIDE_NUMBER / TOTAL_SLIDES)，而不必完全删除页脚。我正在使用Boadilla主题，该主题使用了infolines外部主题。在beamerouterthemeinfolines.sty文件中，我们为脚注找到以下定义:

\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%
}

我需要从本质上重新定义此外部主题，以使其没有\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}，或者定义一个新的外部主题，该主题继承了infolines主题的所有其他内容。我怎样才能做到这一点？

Answer 1

如果愿意，您可以简单地更改文件beameroutertheminfolines.sty，但这可能不是一个好主意。因此，相反，您只需将脚注代码添加到.tex文件中，并删除帧号行，或者像我一样，只需将其转换为注释即可。因此，您将确切部分从beameroutertheminfolines.sty复制到您的.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%
    }
