\section{Introduction}
\label{intro}

The jigsaw package allows to draw adjustable jigsaw pieces in \TikZ, to combine them and even to automatically create complete jigsaws. It is based on the TeX.Stackexchange answers \url{https://tex.stackexchange.com/a/446296/36296}.

The package is included in both \texlive and \miktex and available from \CTAN (\url{https://ctan.org/pkg/jigsaw}). The development version of this package is located at \url{github.com/samcarter/jigsaw}. If you have any problems, ideas or other feedback, please make constructive use of its bug tracker.

\section{Usage}

An individual jigsaw piece can be drawn with

\begin{tcolorbox}[title={Jigsaw piece}]
\begin{lstlisting}
\piece{<bottom>}{<right>}{<top>}{<left>}
\end{lstlisting}
\tcblower
\begin{tikzpicture}
	 \piece{1}{-1}{1}{1}
\end{tikzpicture}
\end{tcolorbox}

wherein arguments specify for each side if it should be a tab (-1), a straight line (0) or a slot (1). The following example will produce a jigsaw piece with one tab sticking out, one straight boarder and two slots:

\begin{tcblisting}{title={Jigsaw piece}}
\begin{tikzpicture}
	 \piece{1}{-1}{0}{1}
\end{tikzpicture}
\end{tcblisting}

With an optional argument, a fill colour can be passed to the piece:

\begin{tcblisting}{title={Filled piece}}
\begin{tikzpicture}
	 \piece[teal]{-1}{1}{-1}{1}
\end{tikzpicture}
\end{tcblisting}

Or to change the line colour:

\begin{tcblisting}{title={Coloured piece}}
\begin{tikzpicture}
	\color{teal}\piece{-1}{-1}{1}{1}
\end{tikzpicture}
\end{tcblisting}

The piece shape is also available as \TikZ \verb|pic|:

\begin{tcblisting}{title={\texttt{pic}}}
\begin{tikzpicture}
	\path (2,-3) pic[
    fill=lightgray,draw=teal,thick
  ]{piece={1}{-1}{1}{0}};
\end{tikzpicture}
\end{tcblisting}

The shapes of the jigsaw pieces are designed to seamlessly fit into each other which allows to produce tile patters in various ways:

\begin{tcblisting}{title={Manual tile pattern}}
\begin{tikzpicture}
\begin{scope}
    \piece[teal]{1}{1}{0}{0}
\end{scope}
\begin{scope}[xshift=1cm]
    \piece[lightgray]{1}{0}{0}{-1}
\end{scope}
\begin{scope}[yshift=-1cm]
    \piece[lightgray]{0}{-1}{-1}{0}
\end{scope}
\begin{scope}[xshift=1cm,yshift=-1cm]
    \piece[teal]{0}{0}{-1}{1}
\end{scope}
\end{tikzpicture}
\end{tcblisting}

\begin{tcblisting}{title={Manual pattern using \texttt{\textbackslash pic}}}
\begin{tikzpicture}
\pic at (0,1) [fill=lightgray,draw]
  {piece={1}{1}{0}{0}};
\pic at (1,1) [fill=teal]
  {piece={1}{0}{0}{-1}};  
\pic at (0,0) [fill=teal]
  {piece={0}{-1}{-1}{0}};  
\pic at (1,0) [fill=lightgray]
  {piece={0}{0}{-1}{1}};     
\end{tikzpicture}
\end{tcblisting}

\begin{tcblisting}{title={Manual pattern using Ti\emph{k}Z matrix}}
% \usetikzlibrary{matrix}
\begin{tikzpicture}
\matrix [nodes=draw]{
\pic [fill=lightgray]{piece={-1}{-1}{0}{0}};&
\pic [fill=teal]{piece={1}{0}{0}{-1}}; \\
\pic [fill=teal]{piece={0}{-1}{1}{0}}; &
\pic [fill=lightgray]{piece={0}{0}{-1}{1}};\\
};
\end{tikzpicture}
\end{tcblisting}

Manually position each jigsaw piece at the correct position can be tedious, therefore the command \lstinline|\tile[<colour>]{<bottom>}{<right>}{<top>}{<left>}| was added. It can be used outside of of the \lstinline|tikzpicture| environment to place the pieces besides each other like normal letters in a text. Line breaks have to be added at the appropriate positions and one has to be careful not to introduce additional spaces between the jigsaw pieces from unprotected line endings.

\begin{tcblisting}{title={The tile command}}
\tile[violet]{1}{1}{0}{0}%
\tile[lightgray]{1}{-1}{0}{-1}%
\tile[teal]{1}{0}{0}{1}

\tile[teal]{1}{-1}{-1}{0}%
\tile[violet]{1}{-1}{-1}{1}%
\tile[lightgray]{-1}{0}{-1}{1}

\tile[lightgray]{0}{-1}{-1}{0}%
\tile[teal]{0}{-1}{-1}{1}%
\tile[violet]{0}{0}{1}{1}
\end{tcblisting}

Finally there is also the possibility to automatically generate complete jigsaw puzzles using the command \lstinline|\jigsaw{<x>}{<y>}|, with \lstinline|<x>| and \lstinline|<y>| the number of rows and columns, respectively.

\begin{tcblisting}{title={Automatic jigsaw generation}}
\begin{tikzpicture}
\jigsaw{6}{4}
\end{tikzpicture}
\end{tcblisting}

This automatically generated jigsaw can also be overlaid on a picture:

\begin{tcblisting}{title={Overlaid image}}
\begin{tikzpicture}
\clip (0,0) rectangle (6,4);
\node at (3,2) {%
  \includegraphics[width=6cm,height=4cm]{example-image-duck}%
};
\jigsaw{6}{4}
\end{tikzpicture}
\end{tcblisting}

\end{document}
