在 Beamer 中，参考书目图标显示在页面之外

Question

我正在用beamer它做一个演示文稿，我注意到参考书目图标在 Beamer 的页面之外呈现。

请参阅下面的代码-

\documentclass[aspectratio=43,11pt]{beamer}
\usetheme{Madrid}
\usecolortheme{seahorse}
\usefonttheme{serif}

\setbeamertemplate{navigation symbols}{}

\usepackage[style=verbose,backend=bibtex]{biblatex}
\renewcommand*{\bibfont}{\tiny}%font size for reference slide
\addbibresource{jobname.bib}

\renewcommand{\footnotesize}{\tiny}

\begin{document}
 \begin{frame}{\textit{cite} example}
  \begin{itemize}
   \item Saharon et al. \footcite{Saharon1972}
   \item Huo et al. \footcite{Huo2002}
  \end{itemize} 
 \end{frame}

 \begin{frame}{References}
    \printbibliography
 \end{frame} 
\end{document}

以下是 bib 文件的内容-

@article{Huo2002,
    author = {Zhimin Huo and Maryellen L. Giger and Olufunmilayo I. Olopade and Dulcy E. Wolverton and Barbara L. Weber and Charles E. Metz and Weiming Zhong and Shelly A. Cummings},
    title = {Computerized Analysis of Digitized Mammograms of BRCA1 and BRCA2 Gene Mutation Carriers},
    journal = {Radiology},
    volume = {225},
    number = {2},
    pages = {519-526},
    year = {2002},
    doi = {10.1148/radiol.2252010845},
    note ={PMID: 12409590},
}
@article{Saharon1972,
author = {Shelah Saharon},
journal = {Annals of Mathematical Logic},
pages = {75--114},
title = {Saturation of ultrapowers and Keisler's order},
volume = {4},
year = {1972},
},

以下是生成的PPT的截图-

请注意，每个参考文献的图标都打印在幻灯片的左侧。但不幸的是，它超出了幻灯片的范围。

问题似乎是infolines由 内部加载的外部主题引起的Madrid。有问题的命令是

\setbeamersize{text margin left=1em,text margin right=1em}

如果您制作了的本地副本beamerouterthemeinfolines.sty，将其重命名并删除上面的行，则可以使用修改后的版本\useoutertheme{bla}。

或者作为一种解决方法，您可以将参考书目包装到minipage.

\documentclass{beamer}
\usetheme{Madrid}
\usepackage[style=verbose,backend=bibtex]{biblatex}
\addbibresource{test.bib}

\begin{document}

    \nocite{*}
    \begin{frame}{References}
        \hspace*{0.5cm}
        \begin{minipage}{\dimexpr\textwidth-1cm\relax}
            \printbibliography
        \end{minipage}
    \end{frame}

\end{document}
