使用动画包隐藏图像

我正在旋转一个三角形，我只希望出现最后两帧的第一个和最后一个三角形。

我想要隐藏第一个三角形和最后一个三角形之间的三角形。

附加乳胶代码。

    \documentclass[12pt]{article}
    \usepackage{animate}

\begin{filecontents}{time.txt}

    },
    end={\end{tikzpicture}},
    controls,timeline=time.txt]{1}

    \draw [color=gray] (-4.5,-3.2) grid (4.5,3.2);

    \foreach \x in {-4,...,4}
    \draw [very thick] (\x,0.1) -- (\x,-0.1) node[below] {\x};
    \foreach \y in {-3,...,3}
    \draw [very thick] (0.1,\y) -- (-0.1,\y) node[left] {\y};

    \draw [<->, very thick] (-4.5,0) -- (4.5,0) node [below] {$x$};
    \draw [<->, very thick] (0,-3.5) -- (0,3.5) node [right] {$y$};

    \draw [line width=1.5pt] (0,1) -- (1,3) -- (3,1) -- cycle;

    \newframe % GIRO 90°

    \draw [color=blue,line width=1.5pt] (-1,0) -- (-3,1) -- (-1,3)-- cycle;

    \draw[color=black] (3.,2.7) node[anchor=north west] {\colorbox{white}{$\alpha=90$}};
    \draw [->,line width=1.5pt](0.5,0) arc (0:90:0.5cm);

    \newframe % GIRO 180°

    \draw [color=blue,line width=1.5pt] (0,-1) -- (-1,-3) -- (-3,-1)-- cycle;

    \draw[color=black] (3.,2.7) node[anchor=north west] {\colorbox{white}{$\alpha=180$}};

    \draw [->,line width=1.5pt](0.5,0) arc (0:270:0.5cm);

    \newframe % GIRO 360°

    \draw [color=blue,line width=1.5pt] (0,1) -- (1,3) -- (3,1)-- cycle;

    \draw[color=black] (3.,2.7) node[anchor=north west] {\colorbox{white}{$\alpha=360$}};

只需将原始的黑色三角形放在动画上透明度自己的。然后在第一个和最后一个动画中使用它框架根据time.txt下面列出的时间线文件。还请注意，最后一个透明胶片中旋转了 360° 的三角形被移除了。

  • 六部动画透明胶片“0 到 5： 在此处输入图片描述

  • 五动画框架0 至 4，组装自透明胶片根据时间线文件

\begin{filecontents}{time.txt}
  ::0x0, 1 % axes+grid, black triangle
  ::2
  ::3
  ::4
  ::5, 1 % black triangle re-used
\end{filecontents}
