复制此幻灯片 - tikz

Question

我想在 Beamer 中重现所附的幻灯片。当然，我并没有要求您帮我制作。我只是想知道您是否知道我应该使用哪个包来制作顶部的蓝色大箭头。任何提示都非常欢迎！我希望这是一个合理的问题 ;)

Answer 1

大蓝色箭头可以用 TikZ 库制作shapes.symbols：chains

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes.symbols,chains}

\tikzset{big blue/.style={signal, text=white, fill=blue, font=\sffamily, minimum height=7mm, minimum width=3.5cm},
    my label/.style={fill=violet,circle, text=white, yshift=1pt}}

\begin{document}

\begin{tikzpicture}[start chain, node distance=0pt]
\node[on chain, big blue, signal to=east, label={[my label]above:{1}}]{Geometry};
\node[on chain, big blue, signal to=east, signal from=west, label={[my label]above:{2}}]{Preprocess};
\node[on chain, big blue, signal to=east, signal from=west, label={[my label]above:{3}}]{Solve};
\node[on chain, big blue, signal to=east, signal from=west, label={[my label]above:{4}}]{Postprocess};

\end{tikzpicture}

\end{document}
