将海报从 A0 横向转换为 A1 纵向

Question

我使用 A0 横向格式的海报模板。我使用的是来自的模板overleaf。海报的设置如下：

\documentclass[final]{beamer}
\usetheme{EastLansing}
\usepackage{natbib}
\bibliographystyle{apalike}
\usepackage[scale=1.24]{beamerposter} 
\usepackage[font={small,it}]{caption} 
\usetheme{confposter} 
\setbeamercolor{block title}{fg=ngreen,bg=white} 
\setbeamercolor{block body}{fg=black,bg=white} 
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} 
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10}
\documentclass[final]{beamer}
\usetheme{EastLansing}
\usepackage{natbib}
\bibliographystyle{apalike}
\usepackage[scale=1.24]{beamerposter}
\usepackage[font={small,it}]{caption}
\usetheme{confposter} 
\setbeamercolor{block title}{fg=ngreen,bg=white} 
\setbeamercolor{block body}{fg=black,bg=white} 
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} 
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10}

我尝试了几种方法将这张海报的格式从 A0 横向改为 A1 纵向。但每次都只是破坏了海报的整个布局。有人知道如何轻松地重新格式化海报的布局吗？
