显示下一帧的注释页

我想自定义 Beamer 中的笔记页面以显示：

  1. 它们引用的当前帧及其编号，
  2. 演示文稿的下一帧及其编号，
  3. 章节和小节，
  4. 笔记本身。

这样做的目的是为了演示者视图用于在辅助屏幕上进行演示（使用分屏显示在 Mac 上）。我注意到对此有相当大的需求，因此我希望以软件包的形式发布解决方案，或者联系 Beamer 维护者并将其提供以供合并。

唯一的问题是，由于我对 LaTeX 编程缺乏经验，我无法弄清楚如何插入下一帧的内容。当前帧（或幻灯片）插入如下（beamerbasenotes.sty）：

\newcommand{\insertslideintonotes}[1]{{%
  \begin{pgfpicture}{0cm}{0cm}{#1\paperwidth}{#1\paperheight}
    \begin{pgflowlevelscope}{\pgftransformscale{#1}}%
      \color[gray]{1}
      \pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\paperwidth}{\paperheight}}
      \pgfusepath{fill}
      \color{black}
      {\pgftransformshift{\pgfpoint{\beamer@origlmargin}{\footheight}}\pgftext[left,bottom]{\copy\beamer@frameboxcopy}}
    \end{pgflowlevelscope}
  \end{pgfpicture}%
  }}

我不明白这\copy\beamer@frameboxcopy代表什么。

您能否为我提供一个命令定义，使之对下一帧而不是当前帧产生相同的效果？

这是不使用任何外部工具即可实现此目的的巧妙方法。这更像是一个“概念验证”，而不是一个完整的解决方案，但我认为即使稍微粗糙一些，它也是有用的。

它使用增强的pgfpages。增强意味着，当pgfpages在物理页面上布局其逻辑页面时，它可以在多个物理页面上进行布局。所以我们要做的是，我们将注释页面和下一个框架页面放在一起，然后像往常一样排版它们：注释后跟框架（因为框架是下一个一），但还有一点额外的：我们还将框架页放在了笔记页的顶角。

通过使用一些小技巧来确保我们在正确的点开始和结束，并且我们实际上并不想使用整个框架，而只想使用其内容（即不是背景），这并不太复杂。这确实意味着我们会得到两个额外的幻灯片：一个在开始，一个在结束，但即使这样也可以在没有太多额外麻烦的情况下处理。

增强的pgfpages被称为pgfmorepages.sty（加拿大运输安全局和github)。这样，下面的代码就可以正常工作了：

当然，应该把这些可怕的东西藏在另一个.sty文件中。另外，我毫不怀疑有更好的布局——我只是破解了当前的布局，将前一张幻灯片的图像放在了顶角。

这将产生以下内容。

带有注释和跟随框架的 Beamer

编辑 2014-09-20

为了回应 anderfo 的评论（我从来没有时间去看）以及通过电子邮件提出的类似问题，我提出以下几点。首先，我应该说，由于我已经很久没有看过这段代码了，我发现我不再完全理解它了！但是，通过我通常的“破解并观察”方法，我设法得到了一些东西（我认为！）模拟了“在第二个屏幕上显示注释=左侧”布局。它还纠正了 Jim 指出的偏移量（再次通过“神奇数字”，而不是通过理解发生了什么）。

（一个小麻烦是，在最后一张幻灯片上，仍然会出现“下一张幻灯片”。我还没想出如何消除它。）

答案2

一个很好的解决方法是https://www.eigenheimstrasse.de/~ben/beamernotepage/。

基本上，makefile 用于首先编译不带注释的普通演示文稿，然后使用该演示文稿中的帧作为带注释版本中的图像。此外，注释页面还添加了一些额外元素，例如部分概述。
