![在 beamer 中部分自动插入为 frametitle](https://linux22.com/image/412598/%E5%9C%A8%20beamer%20%E4%B8%AD%E9%83%A8%E5%88%86%E8%87%AA%E5%8A%A8%E6%8F%92%E5%85%A5%E4%B8%BA%20frametitle%20.png)
我设法重复这个例子用于自定义 beamer 样式。现在我想自动将节和子节标题插入到每张幻灯片的顶部,无需设置\frametitle
,最好通过.sty
文件(即 beamer 外部主题)而不是在.tex
文件中进行设置。
我beamerouterthemetexsx.sty
按照以下方式改编了所引用的示例(参见评论):
\mode<presentation>
% Frame title
\defbeamertemplate*{frametitle}{texsx}[1][]
{
\vskip1cm%
\begin{beamercolorbox}[wd=\paperwidth,ht=1.2cm]{frametitle}
\begin{tikzpicture}
\useasboundingbox[fill=white](0,0) rectangle(\the\paperwidth,1.2);
\fill[orange] (0,0) rectangle(2.95,1.2);
\fill[blue!50!cyan!80] (3.05,0) rectangle(\the\paperwidth,1.2);
% In the next part I replaced \insertframetitle by \insertsection
% In the same way I replaced \insertframesubtitle by \insertsubsection
\ifx\insertframesubtitle\@empty%
{\node[anchor=west, white,font=\large] at (3.2,0.61){\insertsection};}
\else%
{\node[anchor= west, white,font=\large] at (3.2,0.81){\insertsection};%
\node[anchor= west, white,font=\small] at
(3.2,0.41){\insertsubsection};}%
\fi
\end{tikzpicture}
\end{beamercolorbox}
}
\mode<all>

有没有一种简单的方法可以自动获取幻灯片中的标题和副标题,而\begin{frame}
无需设置框架标题和副标题,无论如何都不会使用(如\begin{frame}{auto}{auto}
)?
换句话说,对于代码
\begin{frame}
Blank frame
\end{frame}
我有:
但我期望的是:
