Beamer 都市主题和修改框架页脚 - 扩展框架的水平规则

Question

目标：实现如下目标：

通过修改这个：

\documentclass{beamer}

\usetheme{metropolis}

\def\Vhrulefill{\leavevmode\leaders\hrule height 0.5ex depth 
\dimexpr-.5ex+0.4pt\hfill\kern0pt}

\setbeamertemplate{frame footer}{Tag line \Vhrulefill$\begin{array} {l}\includegraphics[height=0.5cm]{example-image-a}\end{array}$}

\begin{document}
\begin{frame}{Frame title}
Text
\end{frame}
\end{document}

得出的结果是：

Answer 1

这frame footer只是 metropolis 主题（或其更新的分支moloch）中脚注线的第一部分。如果您希望线跨越整个框架，请修改脚注线。

\documentclass{beamer}

\usetheme{moloch}% modern fork of the metropolis theme
\usepackage[export]{adjustbox}

\def\Vhrulefill{\leavevmode\leaders\hrule height 0.5ex depth 
\dimexpr-.5ex+0.4pt\hfill\kern0pt}

\setbeamertemplate{footline}{%
  \begin{beamercolorbox}[wd=\textwidth, sep=3ex]{footline}%
    \usebeamerfont{page number in head/foot}%
    Tag line \Vhrulefill
    \space
    \includegraphics[height=0.5cm,valign=c]{example-image-a}    
    \space
    \usebeamertemplate*{page number in head/foot}
  \end{beamercolorbox}%
}

\begin{document}
\begin{frame}
\frametitle{Frame title}
Text
\end{frame}
\end{document}
