还有一个带 s 的版本pic
。这可能会让构建完整的拼图变得更容易一些。
\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
\tikzset{pics/.cd,
jigsaw/.style={
code={
\fill[#1] (-2,-0.35) to[out=90,in=135] (-1.5,-0.45) arc(-135:135:0.6 and
{0.45*sqrt(2)}) to[out=-135,in=-90] (-2,0.35) |- (-0.35,2)
to[out=0,in=-45] (-0.45,2.5) arc(225:-45:{0.45*sqrt(2)} and 0.6)
to[out=-135,in=180] (0.35,2) -| (2,0.35)
to[out=-90,in=225] (2.5,0.45) arc(135:-135:0.6 and {0.45*sqrt(2)})
to[out=135,in=90] (2,-0.35) |- (0.35,-2)
to[out=180,in=-135] (0.45,-1.5) arc(-45:225:{0.45*sqrt(2)} and 0.6)
to[out=-45,in=0] (-0.35,-2) -| cycle;
}}}
\begin{tikzpicture}
\draw (-2,-2) pic{jigsaw=blue} (2,-2) pic{jigsaw=red}
(-2,2) pic[rotate=90]{jigsaw=purple} (2,2) pic[rotate=90]{jigsaw=green!60!black};
\end{tikzpicture}
\end{document}
更新:使用多用途拼图:语法是
pic{multipurpose jigsaw=fill <color> and <left>/<top>/<right>/<bottom>}
其中<color>
确定填充颜色,其他参数指定凸耳:-1
表示凸耳进入,1
表示凸耳向外,0
表示无凸耳。(还尝试改进颜色。;-)

答案2
基于单侧,可以轻松绘制拼图碎片。在以下示例中,\piece
可以使用宏绘制所需形状的碎片。对于所有四侧,可以控制鼻子是朝外(-1)还是朝内(1)或朝直线(0)。
\documentclass{standalone}
\usepackage{tikz}
\newcommand{\side}[1]{
(0.0,#1*0.00) .. controls (0.0,#1*0.00) and (0.4,#1*-0.04) ..
(0.4,#1*0.04) .. controls (0.4,#1*0.11) and (0.2,#1*0.26) ..
(0.5,#1*0.26) .. controls (0.8,#1*0.26) and (0.6,#1*0.11) ..
(0.6,#1*0.04) .. controls (0.6,#1*-0.04) and (1.0,#1*0.00) ..
(1.0,#1*0.00)
}
\newcommand{\piece}[4]{
\draw
\side{#1}
[rotate around={90:(0.5,0.5)}] \side{#2}
[rotate around={180:(0.5,0.5)}] \side{#3}
[rotate around={270:(0.5,0.5)}] \side{#4};
}
\begin{document}
\begin{tikzpicture}[scale=3]
\piece{1}{1}{1}{1}
\end{tikzpicture}
\begin{tikzpicture}[scale=3]
\piece{1}{-1}{1}{1}
\end{tikzpicture}
\begin{tikzpicture}[scale=3]
\piece{1}{-1}{-1}{1}
\end{tikzpicture}
\begin{tikzpicture}[scale=3]
\piece{1}{-1}{-1}{-1}
\end{tikzpicture}
\begin{tikzpicture}[scale=3]
\piece{-1}{-1}{-1}{-1}
\end{tikzpicture}
\begin{tikzpicture}[scale=3]
\piece{-1}{1}{-1}{1}
\end{tikzpicture}
\end{document}
这些碎片也可以用来拼拼图:
\documentclass{standalone}
\usepackage{tikz}
\newcommand{\side}[1]{
(0.5,0.5) --
(0.0,#1*0.00) .. controls (0.0,#1*0.00) and (0.4,#1*-0.04) ..
(0.4,#1*0.04) .. controls (0.4,#1*0.11) and (0.2,#1*0.26) ..
(0.5,#1*0.26) .. controls (0.8,#1*0.26) and (0.6,#1*0.11) ..
(0.6,#1*0.04) .. controls (0.6,#1*-0.04) and (1.0,#1*0.00) ..
(1.0,#1*0.00)
}
\newcommand{\piece}[5][white]{
\fill[#1]
\side{#2}
[rotate around={90:(0.5,0.5)}] \side{#3}
[rotate around={180:(0.5,0.5)}] \side{#4}
[rotate around={270:(0.5,0.5)}] \side{#5}
-- cycle;
}
\begin{document}
\begin{tikzpicture}
\begin{scope}
\piece[red]{1}{1}{0}{0}
\end{scope}
\begin{scope}[xshift=1cm]
\piece[blue]{1}{-1}{-1}{0}
\end{scope}
\begin{scope}[xshift=2cm]
\piece[green]{1}{0}{1}{0}
\end{scope}
\begin{scope}[yshift=-1cm]
\piece[green]{1}{-1}{0}{-1}
\end{scope}
\begin{scope}[xshift=1cm,yshift=-1cm]
\piece[red]{1}{-1}{1}{-1}
\end{scope}
\begin{scope}[xshift=2cm,yshift=-1cm]
\piece[blue]{-1}{0}{1}{-1}
\end{scope}
\begin{scope}[yshift=-2cm]
\piece[blue]{0}{-1}{0}{-1}
\end{scope}
\begin{scope}[xshift=1cm,yshift=-2cm]
\piece[green]{0}{-1}{1}{-1}
\end{scope}
\begin{scope}[xshift=2cm,yshift=-2cm]
\piece[red]{0}{0}{1}{1}
\end{scope}
\end{tikzpicture}
\end{document}
或者制作一个随机谜题:
\documentclass{standalone}
\usepackage{tikz}
\pgfmathparse{int(random(1,120))}
\newcommand{\side}[1]{
(0.0,#1*0.00) .. controls (0.0,#1*0.00) and (0.4,#1*-0.04) ..
(0.4,#1*0.04) .. controls (0.4,#1*0.11) and (0.2,#1*0.26) ..
(0.5,#1*0.26) .. controls (0.8,#1*0.26) and (0.6,#1*0.11) ..
(0.6,#1*0.04) .. controls (0.6,#1*-0.04) and (1.0,#1*0.00) ..
(1.0,#1*0.00)
}
\newcommand{\piece}[2]{
\draw[ultra thick] \side{#1} [rotate around={90:(0.5,0.5)}] \side{#2};
}
\pgfmathdeclarerandomlist{inout}{{-1}{1}}
\begin{document}
\begin{tikzpicture}[scale=5]
\def\xmax{10}
\def\ymax{10}
\foreach \x in {0,...,\xmax}{
\foreach \y in {0,...,\ymax}{
\ifnum\y=0
\def\bottom{0}
\else
\pgfmathrandomitem{\bottom}{inout}%
\fi
\ifnum\x=\xmax
\def\right{0}
\else
\pgfmathrandomitem{\right}{inout}%
\fi
\begin{scope}[xshift=\x cm, yshift=\y cm]
\piece{\bottom}{\right}
\end{scope}
}
}
\draw (0,0) -- (0,\ymax+1) -- (\xmax+1,\ymax+1);
\end{tikzpicture}
\end{document}
带有背景图像
\documentclass{standalone}

使用坐标计算来绘制旋转形状的选项[out=Angle,in=Angle,out looseness=Value,in looseness=Value]
;然后使用其他技巧来控制大小、角度、位置和颜色。
