Beamerposter 缺少标题

Question

我正在努力用 制作海报演示文稿beamerposter。我只是想重现 github 页面中的示例；其中一个是这个一：

  \documentclass[final]{beamer} % beamer 3.10: do NOT use option hyperref={pdfpagelabels=false} !
  %\documentclass[final,hyperref={pdfpagelabels=false}]{beamer} % beamer 3.07: get rid of beamer warnings
  \mode<presentation> {  %% check http://www-i6.informatik.rwth-aachen.de/~dreuw/latexbeamerposter.php for examples
    \usetheme{Berlin}    %% you should define your own theme e.g. for big headlines using your own logos 
  }
  \usepackage[english]{babel}
  \usepackage[latin1]{inputenc}
  \usepackage{amsmath,amsthm, amssymb, latexsym}
  %\usepackage{times}\usefonttheme{professionalfonts}  % times is obsolete
  \usefonttheme[onlymath]{serif}
  \boldmath
  \usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}                       % e.g. for DIN-A0 poster
  %\usepackage[orientation=portrait,size=a1,scale=1.4,grid,debug]{beamerposter}                  % e.g. for DIN-A1 poster, with optional grid and debug output
  %\usepackage[size=custom,width=200,height=120,scale=2,debug]{beamerposter}                     % e.g. for custom size poster
  %\usepackage[orientation=portrait,size=a0,scale=1.0,printer=rwth-glossy-uv.df]{beamerposter}   % e.g. for DIN-A0 poster with rwth-glossy-uv printer check
  % ...

在我看过的所有例子中，没有必要做一个经典的\maketitle，它应该被纳入到 beamer 模板中，如何在标题中呈现标题。然而我看不到任何标题标题！

这是我编译后得到的结果pdflatex：

我错过了什么？

Answer 1

标准beamer主题是为演示而不是海报设置的，因此它们看起来不合适也就不足为奇了。headline事实上，它运行正常 -\section{Foo}\subsection{Bar}在框架前添加，你可以看到它出现在部分标题中，但以正常大小的文本显示，在海报上看起来很小。

事实上，你给出的代码的评论中也提到了这一点%% you should define your own theme e.g. for big headlines using your own logos

您可能想看看（或直接使用）开发人员为 beamerposter 提供的一些主题，以了解自定义标准主题需要什么https://github.com/deselaers/latex-beamerposter

以下是headline对Berlin主题的简单重新定义，以便以适合的方式使用beamerposter类似的东西可能是必要的footline，或者你可以使用其中一个主题https://github.com/deselaers/latex-beamerposter作为一种更容易被黑客入侵的解决方案
