Beamer 导航栏太长

Beamer 导航栏太长

Beamer 中的导航栏太长了，目前的格式是这样的。我曾考虑过将圆形导航改为多行，但这会导致导航栏的垂直空间占用太多空间。我似乎记得在某个时候看到过一个演示文稿，其中的圆圈会折叠成一个圆圈，除非实际上在当前子部分内，否则它们会重新展开，在那时每个框架都有圆点。

我希望得到一些建议，比如如何保留我所拥有的单行导航栏，以及如何压缩导航栏以使其适合我的宽度。

在此处输入图片描述

我似乎还记得看到过一个演示文稿，其中演示文稿的每个子部分的圆形导航标记之间都有线条，但尚未找到有关如何做到这一点的信息。如果您能告诉我它可能位于何处，那就太好了。

提前致谢。

答案1

beamer 模板迷你框架有 3 个预定义模板：

  • [default]显示小圆圈作为迷你框架
  • [box]显示小矩形作为迷你框架
  • [tick]将小垂直条显示为迷你框架

因此，您可以例如切换到tick模板，因为它不占用太多空间：

\setbeamertemplate{mini frame}[tick]
\setbeamertemplate{mini frame in current subsection}{tick}

但看起来你想保留圆圈。那么为什么不把它们缩小呢？要做到这一点，你必须重新定义模板mini frame。所以我只是复制了模板default，将其重命名scaled circle并引入了一个缩放因子。

\defbeamertemplate{mini frame}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
}
[action]
{
  \newlength{\myminiframesize}
  \setlength{\myminiframesize}{0.14cm}
  \newlength{\myminiframeoffset}
  \setlength{\myminiframeoffset}{0.03cm}
  \setbeamersize{mini frame size=#1\myminiframesize,mini frame offset=#1\myminiframeoffset}
}

\defbeamertemplate{mini frame in current section}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{stroke}
  \end{pgfpicture}%
}

\defbeamertemplate{mini frame in current subsection}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{stroke}
  \end{pgfpicture}%
}

然后你就可以加载它

\setbeamertemplate{mini frame}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current section}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current subsection}[scaled circle]{0.7}

其中0.7是比例因子。

完成 MWE：

\documentclass[compress]{beamer}
\usepackage{calc}
\useoutertheme{miniframes}

\defbeamertemplate{mini frame}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}

    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
}
[action]
{
  \newlength{\myminiframesize}
  \setlength{\myminiframesize}{0.14cm}
  \newlength{\myminiframeoffset}
  \setlength{\myminiframeoffset}{0.03cm}
  \setbeamersize{mini frame size=#1\myminiframesize,mini frame offset=#1\myminiframeoffset}
}

\defbeamertemplate{mini frame in current section}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{stroke}
  \end{pgfpicture}%

    \pgfusepath{stroke}
  \end{pgfpicture}%
