自定义 beamerposter alertblocks

我正在使用该包编写海报beamerposter，并使用朋友给我的模板。在他的模板中，以下代码更改了默认块模板：

\setbeamertemplate{block begin}{
  \vskip1ex
  \begin{beamercolorbox}[rounded=true,shadow=true,leftskip=1cm,colsep*=.75ex]{block title}%
    \usebeamerfont*{block title}\insertblocktitle
  \end{beamercolorbox}%
  {\ifbeamercolorempty[bg]{block body}{}{\nointerlineskip\vskip-0.5pt}}%
  \usebeamerfont{block body}%
  \begin{beamercolorbox}[rounded=true,shadow=true,colsep*=.75ex,sep=.75ex,vmode]{block body}%
    \ifbeamercolorempty[bg]{block body}{\vskip-.25ex}{\vskip-.75ex}\vbox{}%
  }
  \setbeamertemplate{block end}{
  \end{beamercolorbox}
}

这给出了不错的结果。但是，我还想突出显示块，当我使用alertblock或exampleblock时，它们会出现非圆角和无阴影。我该如何将上述设计应用于所有块？

请在将来提供一个最小工作示例。在本例中，我基本上借用了 beamerposter 的 example.tex 来进行工作。我删除了一些无关的细节，但这基本上使用了相同的设置、主题和框架内容，并进行了修改以演示各种块类型。

\documentclass[final]{beamer}
\usetheme{Berlin}
\usepackage[orientation=portrait,size=a0,scale=1.4]{beamerposter}

\newenvironment{mybeamerboxtitle}[1]{%
  \vskip1ex
  \usebeamerfont{#1}%
  \begin{beamercolorbox}[rounded=true,shadow=true,leftskip=1cm,colsep*=.75ex]{#1}}{%
  \end{beamercolorbox}}
\newenvironment{mybeamerboxbody}[1]{%
  {\ifbeamercolorempty[bg]{#1}{}{\nointerlineskip\vskip-0.5pt}}%
  \usebeamerfont{#1}%
  \begin{beamercolorbox}[rounded=true,shadow=true,colsep*=.75ex,sep=.75ex,vmode]{#1}%
    \ifbeamercolorempty[bg]{#1}{\vskip-.25ex}{\vskip-.75ex}\vbox{}%
    }{%
  \end{beamercolorbox}}

\setbeamertemplate{block begin}{%
  \begin{mybeamerboxtitle}{block title}%
    \usebeamerfont*{block title}\insertblocktitle
  \end{mybeamerboxtitle}%
  \begin{mybeamerboxbody}{block body}%
  }
\setbeamertemplate{block end}{%
  \end{mybeamerboxbody}}

\setbeamertemplate{block alerted begin}{%
  \begin{mybeamerboxtitle}{block title alerted}%
    \usebeamerfont*{block title alerted}\insertblocktitle
  \end{mybeamerboxtitle}%
  \begin{mybeamerboxbody}{block body alerted}%
  }
\setbeamertemplate{block alerted end}{%
  \end{mybeamerboxbody}}

\setbeamertemplate{block example begin}{%
  \begin{mybeamerboxtitle}{block title example}%
    \usebeamerfont*{block title example}\insertblocktitle
  \end{mybeamerboxtitle}%
  \begin{mybeamerboxbody}{block body example}%
  }
\setbeamertemplate{block example end}{%
  \end{mybeamerboxbody}}

请注意，灰色背景不是文档本身的一部分，但我需要超越它以确保捕获所有内容，因为投影仪使用零边距。
