为 Beamer 创建精美的章节页面

Question

我目前正在努力创建看起来很花哨的部分页面以Beamer实现以下布局：

根据我对匹配目录的疑问（适合 Beamer 的精美目录) 我想出了以下代码，它看起来不错，但确实与给定的布局非常相似。有什么想法可以改进代码吗？

\documentclass[svgnames]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\pgfdeclarehorizontalshading{section shading}{2cm}{
color(0cm)=(LightSlateGrey!15);
color(3cm)=(LightSlateGrey)
}
\pgfdeclarehorizontalshading{subsection shading}{2cm}{
color(0cm)=(red!15);
color(1cm)=(red);
color(3cm)=(green)
}

\usepackage{tikz}
\tikzset{section number/.style={
    draw=none,
    rectangle,    
    left color=gray!40,
    right color=gray!20!black,
    minimum size=3.5em,
    text=white,
  },
  section/.style={
    draw=none,
    rectangle,    
    shading=section shading,
    minimum height=3.5em,
    minimum width=0.9\textwidth,
    text width=0.9\textwidth,
    text=black,
    align=left
  },
  subsection/.style={
    draw=none,
    rectangle,    
    shading=subsection shading,
    minimum height=2em,
    minimum width=0.9\textwidth,
    text width=0.9\textwidth,
    text=black,
    align=left
  }
}

\begin{document}

\frame{

\begin{tabular}{p{1.2cm}p{9cm}} 
\tikz[baseline=-0.5ex]\node[section number]{\bfseries\Large 123}; & \tikz[baseline=-0.5ex]\node[section]{\bfseries\large fxdfsdf}; \\ & \\
& \tikz[baseline=-0.5ex]\node[subsection]{\bfseries fxdfsdf};
\end{tabular}

}

\end{document}

这是一种可能性；使用 自动创建部分框架\AtBeginSection。我使用了您的颜色和阴影，但您可以轻松更改它们（当然，您可以根据需要随意进行任何其他更改）：

\documentclass[svgnames]{beamer}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{tikz}
\usetikzlibrary{positioning,calc,shadings}

\pgfdeclarehorizontalshading{section shading}{2cm}{
color(0cm)=(LightSlateGrey!15);
color(3cm)=(LightSlateGrey)
}
\pgfdeclarehorizontalshading{subsection shading}{2cm}{
color(0cm)=(red!15);
color(1cm)=(red);
color(3cm)=(green)
}

\tikzset{section number/.style={
    inner sep=0pt,
    draw=none,
    rectangle,    
    left color=gray!40,
    right color=gray!20!black,
    minimum size=3.5em,
    text=white,
    text width=3.5em,
   align=center
  },
  section/.style={
    inner sep=0pt,
    draw=none,
    rectangle,    
    shading=section shading,
    minimum height=3.5em,
    minimum width=0.9\textwidth,
    text width=\the\dimexpr\paperwidth-3.8em\relax,
    text=black,
    align=left
  },
  subsection/.style={
    inner sep=0pt,
    draw=none,
    rectangle,    
    shading=subsection shading,
    minimum height=2em,
    minimum width=0.9\textwidth,
    text width=\the\dimexpr\paperwidth-3.8em\relax,
    text=black,
    align=left
  }
}

\makeatletter
\def\sectionsubtitle#1{\gdef\@sectionsubtitle{#1}}
\AtBeginSection[]{%
\begingroup
\setbeamertemplate{background canvas}{%
\begin{tikzpicture}[remember picture,overlay]
\fill[gray!10] (current page.north west) rectangle (current page.south east);
\fill[left color=red!40,right color=green!15] 
  ( $ (current page.north west) + (0pt,-80pt) $ ) -- 
  ( $ (current page.north west) + (80pt,0pt) $ ) --
  ( $ (current page.north west) + (300pt,0pt) $ ) --
  ( $ (current page.north west) + (0pt,-300pt) $ ) -- 
  cycle;
\fill[left color=LightSlateGrey!40,right color=LightSlateGrey!05]

  cycle;
\end{tikzpicture}
}
\begin{frame}
\begin{tikzpicture}[remember picture,overlay]
\node[section number,anchor=west] at (current page.west) {\fontsize{30}{36}\selectfont\two@digits\thesection}; 
\node[section,anchor=east] at (current page.east) (title) 
  {\hfill\parbox[c][3.5em][c]{\the\dimexpr\paperwidth-4.2em\relax}{\fontsize{20}{20}\selectfont\insertsectionhead}\hfill}; 
\node[subsection,below= 2pt of title]  (subtitle) 
  {\hfill\parbox[c][2em][c]{\the\dimexpr\paperwidth-4.2em\relax}{\@sectionsubtitle}\hfill}; 
\end{tikzpicture}
\end{frame}
\gdef\@sectionsubtitle{}
\endgroup
}
\makeatother

\begin{document}

\sectionsubtitle{Test Subtitle One}
\section{Test Section One}
\begin{frame}
Test Frame
\end{frame}

\sectionsubtitle{Test Subtitle Two}
\section{Test Section Two}
\begin{frame}
Test Frame
\end{frame}

\end{document}

\sectionsubtitle您所要做的就是在每个\section命令前使用。
