框架标题栏和框架边缘之间的边距

2024-5-24 • tag-icon

如何删除下图所示的边距？标题没有任何定义（我只定义了页脚）。框架标题的所有定义选项是：

\setbeamerfont{frametitle}{size={\large}}
\setbeamerfont{framesubtitle}{size={\footnotesize}}

问题在于单位pt不是固定长度，而是取决于当前字体大小。这意味着如果 frametitle 考虑了边距，则此边距的大小与计算 frametitle 在框架上的位置时的大小不同。

为了避免这个问题，请使用固定单位来定义你的边距，例如cm。

\documentclass{beamer}

\setbeamersize{text margin left=0.3cm, text margin right=0.3cm} 
\setbeamercolor{frametitle}{fg=white, bg=black}

\begin{document}

\begin{frame}{Test}
text
\end{frame}

\end{document}
