如何用基本 TikZ 绘制此图

Question

我是 TikZ 新手，也是 LaTeX 新手。因此，使用 TikZ 绘制此图时遇到了困难。

这是我的尝试：

\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[help lines] (0,0) grid (6,6);
\draw (2,3.0) circle (0.5);
\draw (2,1) -- (2,2.5);
\draw (1.5,0)--(2,1.0);
\draw (2.5,0)--(2,1);
\draw (1,1.5)--(2,2);
\draw (3,1.5)--(2,2);
\draw (2.5,3.5) circle (0.1);
\draw (2.75,3.75) circle (0.15);
\draw (2,4) rectangle (6,6);
\node at (4,5) {So it has come to this.};
\end{tikzpicture}
\end{document}

Answer 1

也许您想要如下所示的蓝色线条和无衬线字体：

\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[thick]
\draw[help lines] (0,0) grid (6,6);
\draw (2,3.0) circle (0.5);
\draw (2,1) -- (2,2.5);
\draw (1.5,0)--(2,1.0);
\draw (2.5,0)--(2,1);
\draw (1,1.5)--(2,2);
\draw (3,1.5)--(2,2);
\draw[blue] (2.5,3.5) circle (0.1);
\draw[blue] (2.75,3.75) circle (0.15);
\draw[blue] (2,4) rectangle (6,6) ;
\node[font=\sffamily] at (4,5) {So it has come to this.};
\end{tikzpicture}
\end{document}

Answer 2

对于矩形中的居中文本，不需要定义新的坐标。请参阅下面的 MWE：

\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[font=\sffamily]
\draw[help lines] (0,0) grid (6,6);
\draw (2,3.0) circle (0.5);
\draw (2,1) -- (2,2.5);
\draw (1.5,0)--(2,1.0) -- (2.5,0);
%\draw (2.5,0)--(2,1);
\draw (1,1.5)--(2,2) -- (3,1.5);
%\draw (3,1.5)--(2,2);
\draw (2.5,3.5) circle (0.1);
\draw (2.75,3.75) circle (0.15);
\draw (2,4) rectangle (6,6) 
    node[midway]% this will put text in the middle of rectangle
    {So it has come to this.};
\end{tikzpicture}
\end{document}

在上面的代码中我还加入了“手”和“腿”线条的绘制。
