这个问题导致了一个新的方案的出现：
ocgx
（我已将问题编辑为ocg工具看起来这是正确的选择，而不是动画。
我正在尝试使用乳胶与蒂克兹包来制作由四个层组成的图表。规范要求查看器可以显示或隐藏任何层，因此每个层都需要自己的开/关开关。
这动画包提供了一组控制按钮，适用于需要按预定顺序添加图层的应用程序。我早期尝试制作图表时尝试使用一个动画内联每个层的环境，以便每个层都有自己的一组控制按钮。
我尝试了使用两个层的测试用例动画内联环境，每个都只显示一个空白画布或一个图层，并且每个都有自己的一组控制按钮。各种尝试都不令人满意，包括
尝试 1：在图形环境中，将 animateinline 环境嵌套在另一个环境中。这会导致编译警告，如果忽略该警告，则不会产生任何输出。
尝试 2：在一个图形环境中放置两个独立的 animateinline 环境 - 每组单选按钮独立运行。为了确保第二层叠加在第一层上，我使用 \vspace 手动将第二张图形移动到与第一张图形相同的页面上位置。不幸的是，第二张图形用白色背景完全覆盖了第一张图形，因此看起来第一组单选按钮不起作用，只是因为看不到第一层！
这种尝试存在各种问题：它需要手动摆弄来叠加图层，需要以某种方式使图层透明，即使这样做也意味着控制按钮是叠加的，因此有必要找到一种方法来改变一组控制按钮的位置。
现在发布的答案表明ocg工具将提供一个不需要手动操作的框架，允许透明层，并允许图表创建者放置可以使每个单独的层可见或不可见的链接。一旦我确定该建议符合我的需求，我会报告并使这个问题更简洁。
下面是使用以下方法进行的不令人满意的尝试 2 的一些代码动画。取消注释 vspace 命令会显示不透明的第二层位于第一层之上并遮挡第一层的问题。

% Having this command uncommented causes a problem as the second graphic covers the first - so it appears that the buttons for the first graphic don't work.
% This destroys the illusion of two layers which can be turned on and off independently of each other. Maybe the problem can be
% resolved if the "layers" can be made transparent.

答案1
最后编辑：在 Paul Isambert 的大力帮助下，我编写了这个ocgx软件包。
这是一个带有包的示例ocgx（可通过 CTAN 和 TeXLive 获得）。
三张截图：
代码：
\documentclass{beamer}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{tikz}
\usetikzlibrary{ocgx,calc}
\begin{document}
\tikzset{ocg button/.style={circle,minimum size=.5em,switch ocg with mark on={#1}{}}}
\begin{frame}
\frametitle{Title}
\begin{tikzpicture}[overlay,remember picture,ocg={name=Layer 1,ref=layer1}]
\begin{scope}[shift={(current page)}]
\fill[red,fill opacity=.5] (120:1cm) circle [radius=1.5cm];
\end{scope}
\end{tikzpicture}
\begin{tikzpicture}[overlay,remember picture,ocg={name=Layer 2,ref=layer2}]
\begin{scope}[shift={(current page)}]
\fill[blue,fill opacity=.5] (240:1cm) circle [radius=1.5cm];
\end{scope}
\end{tikzpicture}
\begin{tikzpicture}[overlay,remember picture,ocg={name=Layer 3,ref=layer3}]
\begin{scope}[shift={(current page)}]
\fill[green,fill opacity=.5] (0:1cm) circle [radius=1.5cm];
\end{scope}
\end{tikzpicture}
\begin{itemize}
\item Layer 1 \tikz\node[fill=red!50,ocg button=layer1]{};
\item Layer 2 \tikz\node[fill=blue!50,ocg button=layer2]{};
\item Layer 3 \tikz\node[fill=green!50,ocg button=layer3]{};
\end{itemize}
