为图片创建图块，并对拼图的每个图块添加注释

Question

假设我们在 中有 中的任意.pdf图像。.jpg.png

是否存在一个可以像经典拼图一样将图像分解成碎片的包？

如果可能的话，我希望拼图的每一块也都能够用箭头标注或写下评论。

Answer 1

可以使用pgf键设置图片。

\documentclass[x11names, svgnames, dvipsnames,tikz,border=3.14mm]{standalone}
\begin{document}
\tikzset{pics/.cd,
image jigsaw/.style args={img at #1 and #2/#3/#4/#5}{
    code={%
\draw[path picture={%
\node at #1
{\edef\temp{\noexpand\includegraphics[\pgfkeysvalueof{/tikz/jigsaw/img options}]{\pgfkeysvalueof{/tikz/jigsaw/img}}}
\temp};}] (-2,-0.35) to[out=90,in={90+#2*45}] ({-2+0.5*#2},-0.45) 
arc({-135-(#2-1)*45}:{(#2-1)*180+135+(#2-1)*45}:0.6 and
{0.45*sqrt(2)}) to[out=-90-#2*45,in=-90] (-2,0.35) |- (-0.35,2)
to[out=0,in={0+#3*45}] (-0.45,2-0.5*#3) arc(180-#3*45:{(#3+1)*180+#3*45}:{0.45*sqrt(2)} and 0.6)
to[out=-180-#3*45,in=180] (0.35,2) -| (2,0.35) 
to[out=-90,in=270+#4*45] (2-#4*0.5,0.45) 
arc(90-#4*45:{(#4+1)*180-90+#4*45}:0.6 and {0.45*sqrt(2)})
to[out=90-#4*45,in=90] (2,-0.35) |- (0.35,-2)
to[out=180,in=-180+#5*45] (0.45,-2+#5*0.5) arc(-#5*45:{(#5-1)*180+180+#5*45}:{0.45*sqrt(2)} and 0.6) 
to[out=-#5*45,in=0] (-0.35,-2) -| cycle;
}},
/tikz/jigsaw/.cd,img/.initial={example-image-duck},img options/.initial={}
}
% order : left/top/right/bottom and -1 is out, 1 is in, 0 none
\foreach \X in {0,0.1,...,1,0.9,0.8,...,0.1}
{\begin{tikzpicture}

(1+\X,-1-\X) pic[scale=0.25]{image jigsaw=img at {(-4,4)} and -1/1/0/0}
(-1-\X,0) pic[scale=0.25]{image jigsaw=img at {(4,0)} and 0/1/-1/1}
(0,0) pic[scale=0.25]{image jigsaw=img at {(0,0)} and 1/-1/1/1}
(1+\X,0) pic[scale=0.25]{image jigsaw=img at {(-4,0)} and -1/1/0/-1}
(-1-\X,1+\X) pic[scale=0.25]{image jigsaw=img at {(4,-4)} and 0/0/1/-1}
(0,1+\X) pic[scale=0.25]{image jigsaw=img at {(0,-4)} and -1/0/1/1}
(1+\X,1+\X) pic[scale=0.25]{image jigsaw=img at {(-4,-4)} and -1/0/0/-1};
\end{tikzpicture}}
\end{document}

Answer 2

有一个专门用于拼图的包，用它可以轻松做这样的事情：

\documentclass{article}

\usepackage{jigsaw}
\usepackage{graphicx}

\newcommand{\clippiece}[5][]{%
\begin{scope}
\clip[#1] 
\side{#2} -- (0.5,0.5) [rotate around={90:(0.5,0.5)}] \side{#3} -- (0.5,0.5) [rotate around={180:(0.5,0.5)}] \side{#5} -- (0.5,0.5) [rotate around={270:(0.5,0.5)}] \side{#4} -- (0.5,0.5) -- cycle;   
\node[inner sep=0pt] at (1,-0.7) {\includegraphics[width=3cm]{Lauda_at_1982_Dutch_Grand_Prix}};  % image from https://en.wikipedia.org/wiki/Niki_Lauda#/media/File:Lauda_at_1982_Dutch_Grand_Prix.jpg
\end{scope}     
\begin{scope}[#1]
\piece{#2}{#3}{#4}{#5}
\end{scope}
}

\begin{document}

\tikz{\clippiece{1}{-1}{-1}{1}}
\tikz{\clippiece[xshift=1cm]{-1}{-1}{1}{1}}

\tikz{\clippiece[yshift=-1cm]{-1}{-1}{-1}{-1}}
\tikz{\clippiece[xshift=1cm,yshift=-1cm]{-1}{-1}{1}{1}}

\bigskip

\begin{tikzpicture}
\clippiece{1}{-1}{-1}{1}
\clippiece[xshift=1cm]{-1}{-1}{1}{1}
\clippiece[yshift=-1cm]{-1}{-1}{-1}{-1}
\clippiece[xshift=1cm,yshift=-1cm]{-1}{-1}{1}{1}
\end{tikzpicture}

\end{document}
