制作 beamer 进度条，可以指引讲演者或者是听者更加容易了解到整个 beamer 的进展和进度，下面是五个制作的进度条的样例，大家可以通过修改参数来自定义进度条的颜色、宽度、高度等属性。 第一个： \documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\definecolor{pbblue}{HTML}{0A75A8}% filling color for the progress bar
\definecolor{pbgray}{HTML}{575757}% background color for the progress bar
\makeatletter
\def\progressbar@progressbar{} % the progress bar
\newcount\progressbar@tmpcounta% auxiliary counter
\newcount\progressbar@tmpcountb% auxiliary counter
\newdimen\progressbar@pbht %progressbar height
\newdimen\progressbar@pbwd %progressbar width
\newdimen\progressbar@tmpdim % auxiliary dimension
\progressbar@pbwd=\linewidth
\progressbar@pbht=1.5ex
% the progress bar
\def\progressbar@progressbar{%
\progressbar@tmpcounta=\insertframenumber
\progressbar@tmpcountb=\inserttotalframenumber
\progressbar@tmpdim=\progressbar@pbwd
\multiply\progressbar@tmpdim by \progressbar@tmpcounta
\divide\progressbar@tmpdim by \progressbar@tmpcountb
\begin{tikzpicture}[rounded corners=2pt,very thin]
\shade[top color=pbgray!20,bottom color=pbgray!20,middle color=pbgray!50]
(0pt, 0pt) rectangle ++ (\progressbar@pbwd, \progressbar@pbht);
\shade[draw=pbblue,top color=pbblue!50,bottom color=pbblue!50,middle color=pbblue] %
(0pt, 0pt) rectangle ++ (\progressbar@tmpdim, \progressbar@pbht);
\draw[color=normal text.fg!50]
(0pt, 0pt) rectangle (\progressbar@pbwd, \progressbar@pbht)
node[pos=0.5,color=normal text.fg] {\textnormal{%
\pgfmathparse{\insertframenumber*100/\inserttotalframenumber}%
\pgfmathprintnumber[fixed,precision=2]{\pgfmathresult}\,\%%
}%
};
\end{tikzpicture}%
}
\addtobeamertemplate{headline}{}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=4ex,center,dp=1ex]{white}%
\progressbar@progressbar%
\end{beamercolorbox}%
}
\makeatother
\begin{document}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\end{document}第二款，进度条用的是一个圆球来指示进度： \documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\definecolor{pbblue}{HTML}{0A75A8}% color for the progress bar and the circle
\makeatletter
\def\progressbar@progressbar{} % the progress bar
\newcount\progressbar@tmpcounta% auxiliary counter
\newcount\progressbar@tmpcountb% auxiliary counter
\newdimen\progressbar@pbht %progressbar height
\newdimen\progressbar@pbwd %progressbar width
\newdimen\progressbar@rcircle % radius for the circle
\newdimen\progressbar@tmpdim % auxiliary dimension
\progressbar@pbwd=\linewidth
\progressbar@pbht=1pt
\progressbar@rcircle=2.5pt
% the progress bar
\def\progressbar@progressbar{%
\progressbar@tmpcounta=\insertframenumber
\progressbar@tmpcountb=\inserttotalframenumber
\progressbar@tmpdim=\progressbar@pbwd
\multiply\progressbar@tmpdim by \progressbar@tmpcounta
\divide\progressbar@tmpdim by \progressbar@tmpcountb
\begin{tikzpicture}
\draw[pbblue!30,line width=\progressbar@pbht]
(0pt, 0pt) -- ++ (\progressbar@pbwd,0pt);
\filldraw[pbblue!30] %
(\the\dimexpr\progressbar@tmpdim-\progressbar@rcircle\relax, .5\progressbar@pbht) circle (\progressbar@rcircle);
\node[draw=pbblue!30,text width=3.5em,align=center,inner sep=1pt,
text=pbblue!70,anchor=east] at (0,0) {\insertframenumber/\inserttotalframenumber};
\end{tikzpicture}%
}
\addtobeamertemplate{headline}{}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=4ex,center,dp=1ex]{white}%
\progressbar@progressbar%
\end{beamercolorbox}%
}
\makeatother
\begin{document}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\end{document}
指示方式也可以改为三角形如下： \documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\definecolor{pbgray}{HTML}{575757}% background color for the progress bar
\makeatletter
\def\progressbar@progressbar{} % the progress bar
\newcount\progressbar@tmpcounta% auxiliary counter
\newcount\progressbar@tmpcountb% auxiliary counter
\newdimen\progressbar@pbht %progressbar height
\newdimen\progressbar@pbwd %progressbar width
\newdimen\progressbar@tmpdim % auxiliary dimension
\progressbar@pbwd=\linewidth
\progressbar@pbht=1pt
% the progress bar
\def\progressbar@progressbar{%
\progressbar@tmpcounta=\insertframenumber
\progressbar@tmpcountb=\inserttotalframenumber
\progressbar@tmpdim=\progressbar@pbwd
\multiply\progressbar@tmpdim by \progressbar@tmpcounta
\divide\progressbar@tmpdim by \progressbar@tmpcountb
\begin{tikzpicture}[very thin]
\draw[pbgray!30,line width=\progressbar@pbht]
(0pt, 0pt) -- ++ (\progressbar@pbwd,0pt);
\draw[draw=none] (\progressbar@pbwd,0pt) -- ++ (2pt,0pt);
\draw[fill=pbgray!30,draw=pbgray] %
( $ (\progressbar@tmpdim, \progressbar@pbht) + (0,1.5pt) $ ) -- ++(60:3pt) -- ++(180:3pt) ;
\node[draw=pbgray!30,text width=3.5em,align=center,inner sep=1pt,
text=pbgray!70,anchor=east] at (0,0) {\insertframenumber/\inserttotalframenumber};
\end{tikzpicture}%
}
\addtobeamertemplate{headline}{}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=5ex,center,dp=1ex]{white}%
\progressbar@progressbar%
\end{beamercolorbox}%
}
\makeatother
\begin{document}
\begin{frame}
test
\end{frame}
\begin{frame}
test
\end{frame}
\begin{frame}

\end{frame}
\begin{frame}
test
\end{frame}
\end{document}第三款，放在 beamer 底部的进度指示，颜色更加清晰：
