在 Beamer 中使用 Berkeley 主题时出现对齐问题

Question

在主题中使用框架时，我遇到了对齐问题Berkeley。框架向左重叠，隐藏了后面的栏。你能帮我解决这个问题吗？请参考屏幕截图。

\documentclass{beamer}
\mode<presentation>
  {
    %\usetheme{Berlin}
  %\usetheme{Dreuw}
  %\usetheme{Warsaw}
  %\usetheme{Rochester}
  %\usetheme{PaloAlto}
   %\usetheme{Antibes}
   \usetheme{Berkeley}

   }
  \usepackage{times}
  \usepackage{amsmath,amsthm, amssymb, latexsym}
  \usepackage{ragged2e}

  \boldmath
  \usepackage[english]{babel}
  \usepackage[latin1]{inputenc}
  \usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}

我是 Beamer 的新手。

Answer 1

使用\setbeamersize{text margin left=<width>, text margin right=<width>}。我在以下 MWE 中使用了 4cm 边距（还删除了一些未使用的代码）

\documentclass{beamer}
\mode<presentation>
  {
   \usetheme{Berkeley}
   }
  \usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}
    \setbeamersize{text margin left=4cm, text margin right=4cm} %NEW CODE
