具有許多幻燈片的投影機中的幀編號對齊

Question

使用具有維爾茨堡外部和倒角內部主題的投影儀，我創建了一個包含 100 多張幻燈片的長簡報。 9張投影片後的幀數未正確對齊，總幀數是可見的，但當前幀數位於其上方，我沒有找到正確對齊它的方法。

在最後 30 幀的 MWE 中嘗試了這裡的解決方案：將頁尾文字新增至 Beamer 中的所有投影片但這刪除了原來的腳線背景（顏色主題）。如果取消註釋，則\usecolortheme{shark}當前幀號消失的原因會更明顯。

\documentclass{beamer}
\mode<beamer>{
    \useoutertheme[glossy]{wuerzburg}
    \useinnertheme[shadow,outline]{chamfered}
    \usecolortheme{shark}
}
\setbeamertemplate{navigation symbols}{}

\usepackage{blindtext}

\begin{document}
\begin{frame}[allowframebreaks]{Original footline}
\blindtext[100]
\end{frame}

\setbeamertemplate{footline}[text line]{%
  \parbox{\linewidth}{\vspace*{-8pt}some text\hfill\insertframenumber/\inserttotalframenumber}
}

\begin{frame}[allowframebreaks]{Different footline}
\blindtext[50]
\end{frame}
\end{document}

假設你使用https://github.com/pmagwene/beamer-theme-collection/blob/master/beamerouterthemewuerzburg.sty您可以像這樣更改腳線定義：

\documentclass{beamer}
\useoutertheme[glossy]{wuerzburg}
\useinnertheme[shadow,outline]{chamfered}
\usecolortheme{shark}
\setbeamertemplate{navigation symbols}{}

\usepackage{blindtext}


\makeatletter
\setbeamertemplate{footline}{%
  \ifbeamer@wuerzburg@nofootline
  \else
  \leavevmode%
  \pgfuseshading{beamer@bottomshade}
  \ifbeamer@wuerzburg@glossy%
    \pgfuseshading{beamer@headfootshade}
    \vskip-3.5ex
    \hbox{%
      \begin{beamercolorbox}[wd=.8\paperwidth,ht=2.25ex,dp=1ex,left,ignorebg]{headfoot}%
        \usebeamerfont{author in head/foot}%
        \hspace*{3.5ex}%
        \insertshortauthor{}%
        \beamerwuerzburgthemeadddelimiter{\insertshortinstitute}%
        \beamerwuerzburgthemeadddelimiter{\insertshortdate}%
      \end{beamercolorbox}%
      \begin{beamercolorbox}[wd=.2\paperwidth,ht=2.25ex,dp=1ex,right,ignorebg]{headfoot}%
        \usebeamerfont{date in head/foot}%
        \insertframenumber{} / \if\thelastframecounter0\inserttotalframenumber\else\thelastframecounter\fi \hspace*{3.5ex}
      \end{beamercolorbox}}
  \else%
    \hbox{%
      \begin{beamercolorbox}[wd=.8\paperwidth,ht=2.25ex,dp=1ex,left]{headfoot}%
        \usebeamerfont{author in head/foot}%
        \hspace*{3.5ex}%
        \insertshortauthor{}%
        \beamerwuerzburgthemeadddelimiter{\insertshortinstitute}%
        \beamerwuerzburgthemeadddelimiter{\insertshortdate}%
      \end{beamercolorbox}%
      \begin{beamercolorbox}[wd=.2\paperwidth,ht=2.25ex,dp=1ex,right]{headfoot}%
