绘制矩形的线

Question

我想将节点与复杂形状的边缘连接起来。我只能将其与中心连接起来。

我有以下代码：

\documentclass[tikz]{standalone}

\usetikzlibrary{positioning}
\usetikzlibrary{shapes}
\usetikzlibrary{calc}
\usetikzlibrary{patterns}

\begin{document}
\begin{tikzpicture}[x=5mm,y=5mm]

    \coordinate (S1) at (0,0) {};
    \coordinate (S2) at (3,4) {};

    \draw ($(S1)-(1,2)$) rectangle ($(S1)+(1,2)$);
    \draw[pattern=north west lines] ($(S1)-(1,2)$) rectangle ($(S1)+(1,1)$);

    \node (N2) at (S2) {blubber};

    \draw (S1) -- (N2);


\end{tikzpicture}
\end{document}

结果图像：

Answer 1

不要使用矩形，而要使用节点。您可以定位它们的锚点、调整宽度和高度、填充和绘制边框。然后连接就变得非常容易了。

\documentclass[tikz]{standalone}

\usetikzlibrary{positioning}
\usetikzlibrary{shapes}
\usetikzlibrary{calc}
\usetikzlibrary{patterns}

\begin{document}
\begin{tikzpicture}
    \coordinate (S2) at (3cm,4cm);
    \node[draw,anchor=south west,minimum width=2cm,minimum height=4cm] (R1) at (-1,-2) {};
    \node[draw,anchor=south west,pattern=north west lines,minimum width=2cm,minimum height=3cm] (R2) at (-1,-2) {};
    \node (N2) at (S2) {blubber};

    \draw (R1) -- (N2);


\end{tikzpicture}
\end{document}

Answer 2

这可能是一个解决方案，但不知为何，我不喜欢嵌套的图片。

\documentclass[tikz]{standalone}

\usetikzlibrary{positioning}
\usetikzlibrary{shapes}
\usetikzlibrary{calc}
\usetikzlibrary{patterns}

\begin{document}
\begin{tikzpicture}[x=5mm,y=5mm]

    \coordinate (S1) at (0,0) {};
    \coordinate (S2) at (3,4) {};

    \node[inner sep=0,outer sep=0] (N1) at (S1) {
        \begin{tikzpicture}
            \draw (-1,-2) rectangle (1,2);
            \draw[pattern=north west lines] (-1,-2) rectangle (1,1);

        \end{tikzpicture}
    };

    \node (N2) at (S2) {blubber};

    \draw (N1) -- (N2);


\end{tikzpicture}
\end{document}
