关于 beamer 主题的问题

Question

我非常喜欢 beamer 主题“Air”（您可以通过页面中的“Nice Air based template for Latex”链接找到它http://www.kde.org/kdeslides/)。但有时，在幻灯片中，我的文本有点太长，如果我可以撤回顶部的 air-header.png，那就太好了。所以，你能帮我吗？事实上，我认为最好的想法是修改 ，其中beamerthemeAir.sty包含以下部分：

\setbeamertemplate{headline}
{
  \pgfuseimage{air-header}
  \vskip -1.95cm
  \linethickness{0.0pt}

  \framelatex{
  \begin{beamercolorbox}[wd=\paperwidth,ht=0.3\beamer@headheight]{Title bar}
    \usebeamerfont{section in head/foot}%
    \insertsectionnavigationhorizontal{0pt}{\hskip0.22cm}{}%
  \end{beamercolorbox}}

  \framelatex{
  \begin{beamercolorbox}[wd=\paperwidth,ht=0.7\beamer@headheight]{Title bar}
  \end{beamercolorbox}}
}

变成可选项，例如，只有当幻灯片的标题带有 时，它才会出现\frametitle。如果您不知道，请告诉我，我会从文件中删除此部分sty。

作为保罗·加博利在他的评论中提到，您可以使用plain这些框架的选项（有效地删除标题和脚注），或者您可以使用选项shrink（如果文本太大而无法容纳在框架中，此选项将导致框架的文本缩小）。

在下面的例子中，我在三个不同的框架中展示了相同的内容（取自example-talk.tex），它们有三种设置；第一个是默认行为，显示块突出；第二个显示了普通选项的效果，第三个显示了使用邪恶的选项shrink：

\documentclass[12pt]{beamer}
\usetheme{Air}

就个人观点而言，应避免使用包含过多文字的框架（如果可能）；最好的选择是以适合框架的方式分发材料，而无需进行任何特殊处理。
