Beamer：如何将迷你镜框从圆形改为矩形

我想将迷你框架从圆形改为矩形，并使已经查看的符号与背景颜色相同，未来的符号与前景颜色相同。

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

\makeatletter
\setbeamertemplate{footline}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor~~\beamer@ifempty{\insertshortinstitute}{}{(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
    \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother

和mini frame模板mini frame in current subsection有一个box选项，可以给你正方形而不是圆形（还有一个tick选项可以产生勾号）：

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

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

由于问题要求的是矩形，不一定是正方形，因此beamerbaseauxtemplates.sty可以重新定义模板（如中所定义）；这些模板用于\pgfpathrectangle构建具有相同高度和宽度的矩形：

\pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\the\beamer@boxsize}{\the\beamer@boxsize}}

在下面的代码中我将其更改为

\pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\the\dimexpr0.5\beamer@boxsize\relax}{\the\beamer@boxsize}}

使宽度等于高度的一半。

为了实现颜色方案的更改，还需要重新定义\slideentry（中的原始定义beamerbasenavigation.sty）。我故意将已经访问过的子部分保留为绘制状态，而不是完全涂黑，因为可能需要返回上一张幻灯片：

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

\makeatletter
\setbeamertemplate{mini frame}
{%
  \begin{pgfpicture}{0pt}{0pt}{.1cm}{.1cm}
    \pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\the\dimexpr0.5\beamer@boxsize\relax}{\the\beamer@boxsize}}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
}
\setbeamertemplate{mini frame in current subsection}
{%
  \begin{pgfpicture}{0pt}{0pt}{.1cm}{.1cm}
    \pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\the\dimexpr0.5\beamer@boxsize\relax}{\the\beamer@boxsize}}
    \pgfsetfillcolor{section in head/foot.bg}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
}
