Beamer 簡報中方塊中的標題

Question

1）如何將Beamer中扉頁上的標題放到所需顏色的區塊上？類似地，就像主題華沙、柏林...... 2）如何控製作者和日期之間的空間？\vspace似乎不起作用。

1）我用這個

\title[TITLE]{TITLE\\[1em]
\includegraphics[height=4cm]{logo}\\[1em]}
\subtitle{\textbf{Subtitle}}

但我只想要 TITLE 周圍的方框。我怎樣才能做到這一點？

Answer 1

您可以重新定義title page範本並對佈局進行必要的修改；需要重新定義，因為預設標題和副標題都在同一個內部，beamercolorbox因此只需重新定義title投影機顏色就會在標題和副標題周圍產生一個框（這裡不需要）：

\documentclass{beamer}

\title{TITLE}
\titlegraphic{\includegraphics[height=4cm]{cat}}
\subtitle{\textbf{Subtitle}}
\author{Author}

\setbeamercolor{title}{bg=orange,fg=white}

\makeatletter
\setbeamertemplate{title page}
{
  \vbox{}
  \vfill
  \begin{centering}
    \begin{beamercolorbox}[sep=8pt,center]{title}
      \usebeamerfont{title}\inserttitle
    \end{beamercolorbox}
    \setbeamercolor{title}{bg=white,fg=structure}
    \begin{beamercolorbox}[sep=8pt,center]{title}
      {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
      \ifx\insertsubtitle\@empty%
      \else%
        \vskip0.25em%
        {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
      \fi%     
    \end{beamercolorbox}%
    \vskip1em\par
    \begin{beamercolorbox}[sep=8pt,center]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \vskip-1em\par % change here
    \begin{beamercolorbox}[sep=8pt,center]{institute}
      \usebeamerfont{institute}\insertinstitute
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center]{date}
      \usebeamerfont{date}\insertdate
    \end{beamercolorbox}\vskip0.5em
  \end{centering}
  \vfill
}
\makeatother

\begin{document}

\maketitle

\end{document}

請注意，現在不需要使用，\title[TITLE]{TITLE\includegraphics{...}}但現在您可以簡單地使用\title{TITLE}\titlegraphic{\includegraphics[]{}}`。當然，您可以根據您的特定需求隨意進行必要的調整（您可以使用 \vskip 命令中的長度來調整垂直間距）。

根據評論中的要求，要僅在副標題周圍有一個彩色框，必要的修改如下：

\documentclass{beamer}

\title{TITLE}
\titlegraphic{\includegraphics[height=4cm]{cat}}
\subtitle{\textbf{Subtitle}}
\author{Author}


\makeatletter
\setbeamertemplate{title page}
{
  \vbox{}
  \vfill
  \begin{centering}
    \begin{beamercolorbox}[sep=8pt,center]{title}
      \usebeamerfont{title}\inserttitle
    \end{beamercolorbox}
      {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
      \ifx\insertsubtitle\@empty%
      \else%
        \vskip0.25em%
      \setbeamercolor{title}{bg=orange,fg=white}
      \begin{beamercolorbox}[sep=8pt,center]{title}
        {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
      \fi%     
    \end{beamercolorbox}%
    \vskip1em\par
    \begin{beamercolorbox}[sep=8pt,center]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \vskip-1em\par % change here
    \begin{beamercolorbox}[sep=8pt,center]{institute}
      \usebeamerfont{institute}\insertinstitute
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center]{date}
      \usebeamerfont{date}\insertdate
    \end{beamercolorbox}\vskip0.5em
  \end{centering}
  \vfill
}
\makeatother

\begin{document}

\maketitle

\end{document}

對於新的請求，這裡是隨意更改用於字幕的框的寬度的代碼；根據您的需求變更用於的長度\subtitwd（最初設定為）：4cm

\documentclass{beamer}

\newlength\subtitwd
\setlength\subtitwd{4cm}% change the width here

\makeatletter
\setbeamertemplate{title page}
{
  \vbox{}
  \vfill
  \begin{centering}
    \begin{beamercolorbox}[sep=8pt,center]{title}
      \usebeamerfont{title}\inserttitle
    \end{beamercolorbox}
      {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
      \ifx\insertsubtitle\@empty%
      \else%
        \vskip0.25em%
      \setbeamercolor{title}{bg=orange,fg=white}
      \vbox{%
         \hfill\begin{beamercolorbox}[wd=\subtitwd,sep=8pt,center]{title}
            {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
        \end{beamercolorbox}\hfill\null%
      }%
      \fi%     
    \vskip1em\par
    \begin{beamercolorbox}[sep=8pt,center]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \vskip-1em\par % change here
    \begin{beamercolorbox}[sep=8pt,center]{institute}
      \usebeamerfont{institute}\insertinstitute
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center]{date}
      \usebeamerfont{date}\insertdate
    \end{beamercolorbox}\vskip0.5em
