我怎样才能在 latex 中绘制下面的图形

Question

我想问你如何使用 latex 绘制这幅图。谢谢你的帮助。

Answer 1

除了插入文本外，制作图形非常简单。circledsteps在这里特别有用，因为它允许我们避免嵌套tikzpictures 而不引入\savebox，并且它非常灵活。

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{positioning}
\usepackage{circledsteps}
\colorlet{dred}{red!70!black}
\begin{document}
\begin{tikzpicture}
 \node[font=\Huge\bfseries,align=center,rounded corners=3pt,
 path picture={
  \draw[draw=dred,rounded corners=15pt,line width=3mm]
   ([yshift=-1.51mm]path picture bounding box.south west)
   rectangle ([xshift=1.51mm,yshift=1.51mm]path picture bounding box.north east);
 },inner sep=1em] (MPSI){%
    MPSI\\
    \Circled[outer color=dred,fill color=dred,inner color=white,
        inner ysep=12pt,inner xsep=12pt]{4}};
  \node[right=1ex of MPSI.south east,anchor=south west,path picture={
  \draw[draw=dred,rounded corners=12pt,line width=1.5mm]
   ([yshift=-1.5mm]path picture bounding box.north west)
   -- ([yshift=-1.5mm]path picture bounding box.north east)
    ([yshift=1.5mm]path picture bounding box.south west)
   -- ([yshift=1.5mm]path picture bounding box.south east);
    },inner ysep=3mm,font=\large\bfseries,text width=23em,align=center,
    label={[anchor=south east,text=dred,font=\small,
        inner sep=1pt]north east:Lyc\'ee Omar Ibn Al-Khattab -- Meknes}]{
  Devoir Suveill\'e n\textsuperscript{\textsf{o}}8 de Mathematiques\\[1em]
  {\normalsize La Samedi 21 Mars 2020\hfill Dur\'ee: 4 heures}\\
  };
\end{tikzpicture}
\end{document}
