在两个不同图像中的节点之间画一条线

下面的代码可以在两个圆圈之间画一条线吗？

\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\begin{document} 

\tikzset{
    crcl/.style={draw, thick, shape=circle }
}

\newcommand*{\MyPic}[2]{
    \begin{tikzpicture}
        \draw #1 rectangle #2;
        \node[crcl] at #1 (c) {};
    \end{tikzpicture}
}

\begin{tikzpicture}
    \node[fill=blue] at (0,0) (a) {\MyPic{(0,0)}{(1,1)}}; 
    \node[fill=green] [xshift=2cm] at (0,0) (b) {\MyPic{(0,0)}{(1,1)}}; 
    \draw[thick] (a) -- (b);
\end{tikzpicture}
\end{document}

这与关键且独特的节点名称有关remember picture。

这至少需要两次编译。

另外，我\MyPic以更 TikZ 的方式重新定义：

\MyPic (<p1>) (<p2>) {<name>}

代码

\documentclass[tikz]{standalone}
\tikzset{
    crcl/.style={draw, thick, shape=circle }
}

\newcommand*{\MyPic}[3]{%
    \begin{tikzpicture}[remember picture]
        \draw #1 rectangle #2;
        \node[crcl] at #1 (c#3) {};
    \end{tikzpicture}%
}

\def\MyPic(#1)#2(#3)#4{% remove this if new syntax is not wanted
    \begin{tikzpicture}[remember picture] %
        \draw (#1) rectangle (#3);        %
        \node[crcl] at (#1) (c#4) {};     %
    \end{tikzpicture}%                    %
}%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}
\begin{tikzpicture}[remember picture]
    \node[fill=blue]              at (0,0) (a) {\MyPic (0,0) (1,1) {a}}; 
    \node[fill=green, xshift=2cm] at (0,0) (b) {\MyPic (0,0) (1,1) {b}}; 
    \draw[thick]                           (ca) -- (cb);
\end{tikzpicture}
\end{document}
