投影机中的不完整边规

这仅发生在warsaw主题上：

\documentclass{beamer}
\usetheme{warsaw}
\author{diabonas}
\title{Frame border}
\setbeamertemplate{background canvas}{%
{\color{black}\rule{3pt}{\paperheight}\hspace*{\dimexpr\paperwidth-6pt\relax}\rule{10pt}{\paperheight}}%    
}
\begin{document}
\begin{frame}{content}
content
\end{frame}
\frame{Content}
\begin{frame}
content
\end{frame}
\section{test}
\begin{frame}{Content}
content
\end{frame}
\section{test2}
\end{document}

您可以进行以下重新定义：

\documentclass{beamer}


\mode<presentation>

\useinnertheme[shadow=true]{rounded}
%\useoutertheme{shadow}
\usecolortheme{orchid}
\usecolortheme{whale}

\setbeamerfont{block title}{size={}}

\mode
<all>


\author{diabonas}
\title{Frame border}
\setbeamertemplate{background canvas}{%
{\color{black}\rule{3pt}{\paperheight}\hspace*{\dimexpr\paperwidth-6pt\relax}\rule{10pt}{\paperheight}}%    
}

\makeatletter
\mode<presentation>

\useoutertheme{split}


\setbeamercolor{frametitle}{parent=subsection in head/foot}
\setbeamercolor{frametitle right}{parent=section in head/foot}


\pgfdeclarehorizontalshading[frametitle.bg,frametitle right.bg]{beamer@frametitleshade}{\paperheight}{%
  color(0pt)=(frametitle.bg);
  color(\paperwidth)=(frametitle right.bg)}

\AtBeginDocument{
  \pgfdeclareverticalshading{beamer@topshade}{.982\paperwidth}{%
    color(0pt)=(bg);
    color(4pt)=(black!50!bg)}
}

\addtobeamertemplate{headline}

或者，也可以使用 beamer 3.51 版本，这是唯一支持透明阴影的版本，因此您展示的示例无需任何进一步的修改即可直接使用。
