帶有大都會標題頁的普通投影機演示

Question

我想創建一個演示文稿最小/簡單主題，但有一個漂亮的標題頁，例如都會。我無法弄清楚如何僅使用大都會的標題設置，而不必使用其餘投影片的完整主題（我不喜歡）。我嘗試將大都市主題的標題部分添加到演示文稿中

  \setbeamertemplate{title page}{
  \begin{minipage}[b][\paperheight]{\textwidth}
    \ifx\inserttitlegraphic\@empty\else\usebeamertemplate*{title graphic}\fi
    \vfill%
    \ifx\inserttitle\@empty\else\usebeamertemplate*{title}\fi
    \ifx\insertsubtitle\@empty\else\usebeamertemplate*{subtitle}\fi
    \usebeamertemplate*{title separator}
%    \end{macrocode}
%
% Beamer's definition of |\insertauthor| is always nonempty, so we have
% to test another macro initialized by |\author{...}| to see if the user has
% defined an author. This solution was suggested by Enrico Gregorio in an
% answer to \href{https://tex.stackexchange.com/questions/241306/}{this
% Stack Exchange question}.
%
 %    \begin{macrocode}
    \ifx\beamer@shortauthor\@empty\else\usebeamertemplate*{author}\fi
    \ifx\insertdate\@empty\else\usebeamertemplate*{date}\fi
    \ifx\insertinstitute\@empty\else\usebeamertemplate*{institute}\fi
    \vfill
    \vspace*{1mm}
  \end{minipage}
}

任何幫助表示讚賞。

您需要載入更多元素（並明確載入TikZ）以metropolis在預設投影機主題上重現標題框架。

以下程式碼僅載入title frame格式，使用的顏色來自預設主題。

\documentclass{beamer}
\usepackage{tikz}

\makeatletter
\setbeamertemplate{title page}{
  \begin{minipage}[b][\paperheight]{\textwidth}
    \ifx\inserttitlegraphic\@empty\else\usebeamertemplate*{title graphic}\fi
    \vfill%
    \ifx\inserttitle\@empty\else\usebeamertemplate*{title}\fi
    \ifx\insertsubtitle\@empty\else\usebeamertemplate*{subtitle}\fi
    \usebeamertemplate*{title separator}
    \ifx\beamer@shortauthor\@empty\else\usebeamertemplate*{author}\fi
    \ifx\insertdate\@empty\else\usebeamertemplate*{date}\fi
    \ifx\insertinstitute\@empty\else\usebeamertemplate*{institute}\fi
    \vfill
    \vspace*{1mm}
  \end{minipage}
}
\def\maketitle{%
  \ifbeamer@inframe
    \titlepage
  \else
    \frame[plain,noframenumbering]{\titlepage}
  \fi
}
\def\titlepage{%
