我有以下代码,它使用了animateinline
一些tikzpicture
动画效果:
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{ifthen}
\usepackage{animate}
\usetheme{Warsaw}
\usecolortheme{whale}
\def\layera{
\path[cm={{0.8028232,-0.59621716,0.59621716,0.8028232,(0.0,0.0)}},draw=black,opacity=0.990,miter
limit=4.00,line width=0.943pt,rounded corners=0.0000cm] (-99.8372,584.6912)
rectangle (-30.7483,653.7801);
}
\def\layerb{
\fill[blue!40] (0,0) circle (1);
}
\def\layerc{
\fill[red!40] (0,0) circle (1);
}
\begin{document}
\begin{center}
\begin{frame}
\begin{animateinline}[loop,controls]{1}
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layera{}
\end{tikzpicture}
\newframe
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layerb{}
\end{tikzpicture}
\newframe
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layerc{}
\end{tikzpicture}
\newcommand{\makelayer}{
\newframe
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layerc{}
\end{tikzpicture}
}
%\makelayer{}
%\def\MyLayers{\layerb, \layerc}
%\foreach \mylayer in \MyLayers {
% \newframe
% \begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
% \mylayer{}
% \end{tikzpicture}
%}
\end{animateinline}
\end{frame}
\end{center}
\end{document}
如您所见,它有 3 个层(1 个层/帧):layera、layerb 和 layerc。以下文件可以转换为 pdf,并且动画效果正确:一个正方形,然后是一个蓝色圆圈和一个红色圆圈。
但是,当我尝试使用\newcommand
makelayer 时,输出不正确:只需取消注释\makelayer{}
并编译为 pdf。奇怪的是 layerb 没有正确显示,而是在里面的 layerc \makelayer{}
?
\newcommand
对于训练有素的眼睛来说,这一定是显而易见的事情;有人能指出在这种情况下正确的使用方法是什么吗?
第二个问题是循环遍历所有 tikzpictures,我认为这可能与上面的问题有关。我还注释掉了不起作用的代码,从以下位置开始:%\def\MyLayers{\layerb, \layerc}
任何帮助深表感谢。

@Harish 的回答解决了第一个问题。
为了澄清我的第二个问题,即如何tikzpicture
使用foreach
或任何其他循环机制循环遍历每个内容?我对代码做了一些更改来说明这个问题(实际的 tex 文件可能包含更多层/ tikzpicture
):
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{ifthen}
\usepackage{animate}
\usetheme{Warsaw}
\usecolortheme{whale}
\newcommand\layera{%
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\path[cm={{0.8028232,-0.59621716,0.59621716,0.8028232,(0.0,0.0)}},draw=black,opacity=0.990,miter
limit=4.00,line width=0.943pt,rounded corners=0.0000cm] (-99.8372,584.6912)
rectangle (-30.7483,653.7801);
\end{tikzpicture}
}
\newcommand\layerb{%
\fill[blue!40] (0,0) circle (1);
}
\newcommand\layerc{%
\fill[red!40] (0,0) circle (1);
}
\begin{document}
\begin{center}
\begin{frame}
\begin{animateinline}[loop,controls]{1}
\layera
\newcommand{\makemylayer}{%
\newframe
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layerb
\end{tikzpicture}
\newframe
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\layerc
\end{tikzpicture}
}
\makemylayer
%\newcommand\MyLayers{\layerb, \layerc}
%\foreach \mylayer in \MyLayers {
% \newframe
% \begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
% \mylayer{}
% \end{tikzpicture}
%}
\end{animateinline}
\end{frame}
\end{center}
\end{document}
有 3 层(tikzpicture
):layera、layerb 和 layerc,除了 layera,我想循环遍历每层tikzpicture
(layerb 和 layerc)的内容。
因此,当我注释掉\makemylayer
、取消注释该foreach
块时,当我尝试编译时,出现以下错误消息:
! Package animate Error: Contents of first frame must not have zero width.
感谢您的帮助。

loop
我尝试过其他循环方法,例如forloop
等,但大多数都涉及计数器或类似的东西;有人能否就如何遍历上述命令列表并使其工作提供任何建议?
非常感谢。

通过在后面添加一个 即可解决您的第一个问题\newcommand{\makelayer}{
。
我觉得我没有正确理解你的第二个问题。可以按照你修改后的代码所示进行操作。
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{ifthen}
\usepackage{animate}
\usetheme{Warsaw}
\usecolortheme{whale}
\newcommand\layera{%
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\path[cm={{0.8028232,-0.59621716,0.59621716,0.8028232,(0.0,0.0)}},draw=black,opacity=0.990,miter
limit=4.00,line width=0.943pt,rounded corners=0.0000cm] (-99.8372,584.6912)
rectangle (-30.7483,653.7801);
\end{tikzpicture}
}
\newcommand\layerb{%
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\fill[blue!40] (0,0) circle (1);
\end{tikzpicture}
}
\newcommand\layerc{%
\begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\fill[red!40] (0,0) circle (1);
\end{tikzpicture}
}
\begin{document}
\begin{center}
\begin{frame}
\begin{animateinline}[loop,controls]{1}
\layera
\newframe
\layerb
\newframe
\layerc
\newcommand{\makelayer}{%
\newframe
\layerb
}
\makelayer
%\def\MyLayers{\layerb, \layerc}
%\foreach \mylayer in \MyLayers {
% \newframe
% \begin{tikzpicture}[y=0.20pt,x=0.20pt,yscale=-1, inner sep=0pt, outer sep=0pt]
% \mylayer{}
% \end{tikzpicture}
%}
%% Instead of above try this:
\newcommand{\makemylayer}{%
\newframe
\layera
\newframe
\layerc
\newframe
\layerb
}
\makemylayer
\end{animateinline}
\end{frame}
\end{center}
\end{document}
我改变了出现的顺序以使事情变得更清楚。
