无法将图片连接到节点

Question

不幸的是，我无法将节点 Client1 连接到端口 13。下面显示了我的失败尝试。我知道与节点不同，pics 无法在以后引用。有人能帮我将 port/.pic 转换为以后可以引用的节点吗？我的示例中的红色圆圈仅供参考。

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{calc, shadings, shadows, shapes.arrows}
\usetikzlibrary{positioning}

\tikzset{
    port/.pic={% style, size, label
        \tikzset{port/.cd,#1}
        \coordinate[] (main) at (0cm,0cm);
        \coordinate[] (labelposition) at (.5cm,1.2cm);
        \draw[port/rect] (main) rectangle (\pgfkeysvalueof{/tikz/port/tr});
        \draw[fill=black] (.1cm,0cm) rectangle (.9cm,.5cm);
        \draw[fill=black] (.2cm,.5cm) rectangle (.8cm,.7cm);
        \draw[fill=black] (.4cm,.7cm) rectangle (.6cm,.8cm);
        \node (labelnode) at (labelposition) 
        {\pgfkeysvalueof{/tikz/port/label}};  
    },
    port/.cd,

        path picture={
            \draw[top color=gray!5,bottom color=gray!40](path picture bounding box.south west) rectangle (path picture bounding box.north east);
            %
            \coordinate (A-west) at([xshift=1cm,yshift=.2]path picture bounding box.west);
            %
            \draw[rack switch/point] (A-west) circle  ;
            %
            \coordinate (A-center) at ($(path picture bounding box.center)!0!(path picture bounding box.south)$);

            %
            \foreach \x/\a in {0/1,1.2/2,2.4/3,3.6/4,4.8/5,6/7,7.2/8,8.4/9,9.6/10,10.8/11, 12/12, 13.2/13}{
                \pic(\a) at ($(A-west)+(\x,0cm)$){port={label=\a}};     
            }
            \foreach \x/\b in {1/14,2.2/15,3.4/16, 4.6/17, 5.8/18, 7/19, 8.2/20, 9.4/21, 10.6/22, 11.8/23, 13/24, 14.2/25}{

        }
    },
    rack switch/.cd,

正如 Black Mild 所建议的，您需要nodes在其中包含pic对它们的引用。

以下代码显示了交换机的另一个版本。完整的switch是pic，每个端口都是一个node，并带有一个用于path picture绘制孔。

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{calc, shadings, shadows, shapes.arrows, matrix}
\usetikzlibrary{positioning}

\tikzset{
    port_up/.style={draw, top color=gray!5, bottom color=gray!40, minimum width=1cm, minimum height=1.5cm, 
        path picture={\fill ([xshift=1mm]path picture bounding box.south west)|-++(1mm,5mm)|-++(2mm,2mm)|-++(2mm,1mm)|-++(2mm,-1mm)|-++(1mm,-2mm)|-cycle;}, label={[anchor=north, outer sep=1mm]north:#1}},
    port_down/.style={draw, top color=gray!5, bottom color=gray!40, minimum width=1cm, minimum height=1.5cm, 
        path picture={\fill ([xshift=1mm]path picture bounding box.north west)|-++(1mm,-5mm)|-++(2mm,-2mm)|-++(2mm,-1mm)|-++(2mm,1mm)|-++(1mm,2mm)|-cycle;}, label={[anchor=south, outer sep=1mm]south:#1}},    
    switch/.pic={
        \node[minimum width=20cm, minimum height=4cm, draw, top color=gray!5,bottom color=gray!40] (-body) {};
        \path[fill=red!50] ([shift={(1cm,.2cm)}]-body.west) coordinate (-A) circle (.2);
        \path[fill=red!50] (-body.center) circle (.2);
        \path[fill=red!50] (-body.east)++(90:.2) arc (90:270:.2)--cycle;
        \foreach \i [count=\topi from 1, count=\bottomi from 14] in {1,...,13}{
            \node[port_up=\topi, anchor=south west] (-\topi) at ([xshift=(\i-1)*1.1cm]-A) {}; 
            \node[port_down=\bottomi, anchor=north, below=2mm of -\topi] (-\bottomi){}; 
        }
    },
}
        
\begin{document}
\begin{tikzpicture}

\path pic (Switch1) {switch};

\node[above right=2cm of Switch1-body] (Client) {\includegraphics{fileserver}};
\draw[red] (Client) -- (Switch1-13);
\draw[green, ultra thick] (Switch1-16.center) to[out=280, in=-100] (Switch1-22.center);

\end{tikzpicture}
\end{document}
