![beamercolorbox 的虚线边框](https://linux22.com/image/442960/beamercolorbox%20%E7%9A%84%E8%99%9A%E7%BA%BF%E8%BE%B9%E6%A1%86.png)
是否可以绘制带有虚线边框的 beamercolorbox?我在 Beamer 文档中找不到此类装饰的可能性。
答案1
您可以使用tcolorbox
:
\documentclass[aspectratio=169]{beamer}
\usetheme{default}
\usepackage[most]{tcolorbox}
\setbeamertemplate{blocks}[rounded][shadow=true]
%\setbeamercolor{block body example}{bg=red!20!white}
%\setbeamercolor{block title example}{fg=red, bg=red!40!white}
% \definecolor{bitsdeepBlue}{RGB}{42, 42, 134}
\newtcolorbox{myblock}[1][]{%
enhanced jigsaw,%
colback=red!20!white!90!,%
% colframe=red!85!white!90!,%
colbacktitle=red!45!white!90!,
% size=small,%
% boxrule=1pt,%
title=\textbf{\textit{Example}},%
halign title=flush left,%
coltitle=red,%
breakable,%
drop fuzzy shadow=black!70!white,%
left=0pt,
titlerule=0pt,
top=1pt,
bottom=0pt,
enlarge left by=-0.1cm,
grow to right by=0.21cm,
frame empty,
borderline={0.5mm}{0mm}{red!85!white!90!,dashed},
}
\begin{document}
\begin{frame}{Frame Title}
\begin{myblock}
this is default.
\end{myblock}
\end{frame}
\end{document}
使用新的 tcolorbox 内部主题(https://www.ctan.org/pkg/beamertheme-tcolorbox),添加虚线边框现在变得更加简单:
\documentclass[aspectratio=169]{beamer}
\usetheme{Warsaw}
\useinnertheme{tcolorbox}
\tcbset{
borderline={1.5pt}{-1.5pt}{block title.bg,dashed},
}
\begin{document}
\begin{frame}
\begin{block}{title}
this is default.
\end{block}
\end{frame}
\end{document}
