如何在 beamer 的标题页顶部中央添加 logo 并优化模板

Question

beamer我正在使用主题制作演示文稿Madrid。我想在标题页的顶部中央添加机构徽标。最有效的方法是什么？

我已经按照以下方式完成：

\documentclass[aspectratio=43]{beamer}  
%------------------------------------
\mode<presentation>{
\usetheme{Madrid}
}
\setbeamercolor{section in head/foot}{fg=white,bg=black}           % https://tex.stackexchange.com/a/326553/114006
\makeatletter
\setbeamertemplate{headline}{%
    \begin{beamercolorbox}[ht=2.25ex,dp=3.75ex]{section in head/foot}
        \insertnavigation{\paperwidth}
    \end{beamercolorbox}%
}%
\makeatother
%------------------------------------
\title{Presentation Title}
\titlegraphic{\includegraphics[width=1cm]{example-image}}
\author{Presenter Name} 
\date{August, 2021} 
\logo{\includegraphics[height=0.5cm,keepaspectratio]{example-image}}

\begin{document}
{
\setbeamercolor{page number in head/foot}{fg=date in head/foot.bg}          % https://tex.stackexchange.com/a/412733/114006
\begin{frame}[noframenumbering, plain]
\titlepage
\end{frame}
}
\section{Section 1} 
\begin{frame}
\frametitle{Section One}
Sed iaculis dapibus gravida.
\end{frame}
\setbeamercolor{page number in head/foot}{fg=date in head/foot.bg}
% \bulletoff\section*{}
\begin{frame}[noframenumbering]
\Huge\centerline{Thank You.} 
\huge\centerline{Any Question?}
\end{frame}

\end{document}

除了logo问题，希望大家能给些建议，优化一下整体模板代码，哪些地方可以改进？

最简单的方法是在之前添加您的徽标\titelpage：

\documentclass[aspectratio=43]{beamer}  
%------------------------------------
\mode<presentation>{
\usetheme{Madrid}
}
\setbeamercolor{section in head/foot}{fg=white,bg=black}           % https://tex.stackexchange.com/a/326553/114006
\makeatletter
\setbeamertemplate{headline}{%
    \begin{beamercolorbox}[ht=2.25ex,dp=3.75ex]{section in head/foot}
        \insertnavigation{\paperwidth}
    \end{beamercolorbox}%
}%
\makeatother
%------------------------------------
\title{Presentation Title}
\titlegraphic{\includegraphics[width=1cm]{example-image}}
\author{Presenter Name} 
\date{August, 2021} 
\logo{\includegraphics[height=0.5cm,keepaspectratio]{example-image}}

\begin{document}
{
\setbeamercolor{page number in head/foot}{fg=date in head/foot.bg}          % https://tex.stackexchange.com/a/412733/114006
\begin{frame}[noframenumbering, plain]
\centering
\includegraphics[width=3cm]{example-image-duck}
\titlepage
\end{frame}
}


\end{document}
