Beamer - 如何自定义法兰克福幻灯片的标题？

我使用以下选项：

\usetheme{Frankfurt}
\setbeamercolor{section in head/foot}{fg=black, bg=white}

生成的幻灯片如下：

是否可以

  • 让“第 1 部分”和“第 2 部分”更加紧密地结合在一起？
  • 在框架标题前绘制分隔线？

答案1

当然可以。您可以重新定义模板；我使用高度和之前设置的颜色headline制作了分隔线。beamercolorbox.75exupper separation line head

\insertnavigation我没有使用 ，而是使用了\insertsectionnavigationhorizontal，因为它允许进行更多控制。我使用了颜色red，因为您没有提供代码片段中使用的颜色方案的完整信息。您可以根据需要随意更改设置：

\documentclass{beamer}
\usetheme{Frankfurt}

\setbeamercolor{section in head/foot}{fg=black, bg=white}
\setbeamercolor{frametitle}{fg=red, bg=white}
\setbeamercolor{upper separation line head}{bg=red}

\makeatletter
\setbeamertemplate{headline}
{%
  \pgfuseshading{beamer@barshade}%
  \ifbeamer@sb@subsection%
    \vskip-9.75ex%
  \else%
    \vskip-7ex%
  \fi%
  \begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
    \insertsectionnavigationhorizontal{\paperwidth}{}{\hfill\hfill}
  \end{beamercolorbox}%
  \ifbeamer@sb@subsection%
    \begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}\insertsubsectionhead
    \end{beamercolorbox}%
  \fi%
 \begin{beamercolorbox}[colsep=1.5pt,ht=.75ex]{upper separation line head}
 \end{beamercolorbox}
}%
\makeatother

作为克劳迪奥·菲安德里诺在他的评论中提到，使用

\insertsectionnavigationhorizontal{\paperwidth}{\hskip0pt plus1fill}{\hskip0pt plus1fill}

代替

\insertsectionnavigationhorizontal{\paperwidth}{}{\hfill\hfill}

将在导航栏中产生居中部分。

以前的方法有一个缺点：不再包括小节的指标。为了恢复指标并使章节标题更接近，\insertnavigation需要重新定义：

\documentclass{beamer}
\usetheme{Frankfurt}

\setbeamercolor{section in head/foot}{fg=black, bg=white}
\setbeamercolor{frametitle}{fg=red!70!black, bg=white}
\setbeamercolor{upper separation line head}{bg=red!70!black}

\makeatletter
\def\insertnavigation#1{%
  \vbox{{%
    \usebeamerfont{section in head/foot}\usebeamercolor[fg]{section in head/foot}%
    \beamer@xpos=0\relax%
    \beamer@ypos=1\relax%
    \hbox to #1{\hskip.3cm\setbox\beamer@sectionbox=\hbox{\kern1sp}%
      \ht\beamer@sectionbox=1.875ex%
      \dp\beamer@sectionbox=0.75ex%
        \hskip.3cm%
        \global\beamer@section@min@dim\z@
        \dohead%
        \beamer@section@set@min@width
      \box\beamer@sectionbox\hfill\hskip.3cm}%
  }}}

\setbeamertemplate{headline}
{%
  \pgfuseshading{beamer@barshade}%
  \ifbeamer@sb@subsection%
    \vskip-9.75ex%
  \else%
    \vskip-7ex%
  \fi%
  \begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
    \insertnavigation{\paperwidth}
  \end{beamercolorbox}%
  \ifbeamer@sb@subsection%
    \begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}\insertsubsectionhead
    \end{beamercolorbox}%
  \fi%
 \begin{beamercolorbox}[colsep=1.5pt,ht=.75ex]{upper separation line head}

答案2

还有一个有点 hack 的（或者说是务实的，如果你允许我出售它的话：P）版本是减少包含导航项目的 beamercolorbox 的长度。我实际上是从主题中复制粘贴了标题定义，smoothbars并添加了 0.5 倍的系数。你可以根据部分的大小/数量调整它们应该展开多少。我只是从 Gonzalo 的答案中复制了线条解决方案。

\documentclass{beamer}
\usetheme{Frankfurt}
\setbeamercolor{upper separation line head}{bg=red}
\setbeamercolor{section in head/foot}{fg=black, bg=white}
\setbeamercolor{frametitle}{fg=red, bg=white}

\makeatletter
\setbeamertemplate{headline}
{%
  \pgfuseshading{beamer@barshade}%
  \ifbeamer@sb@subsection%
    \vskip-9.75ex%
  \else%
    \vskip-7ex%
  \fi%
  \begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
    \insertnavigation{0.5\paperwidth} % <======= Added 0.5 here
  \end{beamercolorbox}%
  \ifbeamer@sb@subsection%
    \begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}\insertsubsectionhead
    \end{beamercolorbox}%
  \fi%
     \begin{beamercolorbox}[colsep=1.5pt,ht=.75ex]{upper separation line head}
 \end{beamercolorbox}
