繪製直線到矩形

Question

我想將節點與複雜形狀的邊緣連接起來。我只能將其與中心連接起來。

我有以下程式碼：

\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}

結果影像：

Answer 1

使用節點代替矩形。您可以定位它們的錨點、調整寬度和高度、填充和繪製邊框。那麼連接就變得非常容易。

\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

這將是一個解決方案，但不知何故我不喜歡嵌套圖片。

\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}
