Metropolis Beamer 中的多条页脚线

Question

我们如何才能添加一条额外更宽的线，并与标题具有相同的颜色背景，以便在幻灯片的右下角包含该机构的徽标？

目前调整后的页脚如下：

\documentclass{beamer}

\usetheme{metropolis}
\setbeamertemplate{frame footer}{\insertshortauthor~(\insertshortinstitute)\hfill\insertshorttitle}

\setbeamerfont{page number in head/foot}{size=\tiny}
\setbeamercolor{footline}{fg=gray}

\author{names}
\institute{institute}
\title{Quack}

\begin{document}
\begin{frame}
content...
\end{frame}
\end{document}

Answer 1

您可以像下面这样重新定义 fooline：

\documentclass{beamer}

\usetheme{moloch}% modern fork of the metropolis theme
\setbeamertemplate{frame footer}{\insertshortauthor~(\insertshortinstitute)\hfill\insertshorttitle}

\setbeamerfont{page number in head/foot}{size=\tiny}
%\setbeamercolor{footline}{fg=gray}

\author{names}
\institute{institute}
\title{Quack}

\setbeamercolor{footline}{fg=black!2, bg=mDarkTeal}

\makeatletter
\setbeamertemplate{footline}{%
    \begin{beamercolorbox}[wd=\textwidth, sep=1ex]{footline}
        \usebeamerfont{page number in head/foot}%
        \usebeamertemplate*{frame footer}
        \hfill%
        \raisebox{-2ex}{\includegraphics[height=6ex]{example-image-duck}}
    \end{beamercolorbox}%
}
\makeatother

\begin{document}
\begin{frame}
content...
\end{frame}
\end{document}
