如何使用 tikz-nodes 放置和显示外部图像？

Question

这里有一个方法。在运行此示例之前，请将 3 幅图像复制到与 .tex 文件相同的目录中，并将它们重命名为 img-1.X、img-2.X 和 img-3.X，其中X表示图形格式png，如jpg等。

像往常一样放置并绘制一个节点，然后将\includegraphics[height=1cm]{img-1}节点括号内的内容放在要放置文本的位置。

如果以后要连接节点，请命名它们。照常绘制连接，例如使用语句\graph。

\documentclass[10pt, border=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{graphs}% needed for the \graph - statement


% DO BEFOREHAND: copy and rename 3 images img-1 to img-3 to the same directory
\begin{document}

\tikz {
    % --- that's all you need to place and show an image by a node ---
    \node [draw=red] at (0,4)       {\includegraphics[height=1cm]{img-1}};
    
    % --- to connect nodes it's practical to name the nodes ---
    \node (brd) [draw] at (0,0)     {\includegraphics[height=2cm]{img-1}};
    \node (stk) [draw] at (5,0)     {\includegraphics[height=2cm]{img-3}};
    \node (set) [draw] at (3.5, 3.5)    {\includegraphics[height=2cm]{img-2}};

    % --- let the sticks point towards two image-nodes ---
    \graph {
        (stk) -> [blue] {(brd), (set)}% reference aboves nodes by paranthesis ()
    };
}

\end{document}

受到 David 的评论启发“\includegraphics您可以在可以使用文本的任何地方使用“也可以将倾斜的图像附加到连接线上：

\documentclass[10pt, border=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{graphs}% needed for the \graph - statement


% DO BEFOREHAND: copy and rename 3 images img-1 to img-3 to the same directory
\begin{document}

\tikz {
    
    % --- to connect nodes it's practical to name the nodes ---
    \node (brd) [draw] at (0,0)     {\includegraphics[height=2cm]{img-3}};
    \node (set) [draw] at (3.5, 3.5)    {\includegraphics[height=2cm]{img-2}};


    % --- connecting with a sloped text above ----
    \draw (brd) -- node [sloped, above] {\small{label}} (set);
    
    % --- connecting, with sloped image below and a curved connector ---
    \draw [->] (brd) to [out=-30 , in=-100] 
        node [sloped, below] {\includegraphics[height=1cm]{img-1}} (set);
}

\end{document}

因为初学者tikz有时会遇到困难，所以如果您愿意，可以反向应用 David 的建议：只采用经典的文本放置和样式，而不使用任何图像。

代码结构是从上一个示例中复制而来的，引入了文本的简写符号，提供了一些样式，放置了两个文本节点，提供了两个带有文本标签的连接器。

您的收获：tikz 中的结构仍然相同，只有处理的内容发生了变化（从图像到文本）。

\documentclass[10pt, border=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{graphs}% needed for the \graph - statement

% --- "text variables" to keep code cleaner -----------------
\def\stks{sticks}
\def\drst{Drummers set shown from Clyde Stubblefield and Yogi Horton}
\def\brd{drumset board}

\begin{document}

\tikz [dst/.style={text width=2cm, node font=\tiny},% styling the drums text
       lbls/.style={node font=\small, color=blue}, sloped]% styling the label texts
    {
    
    % --- to connect by graphs it's practical to name the nodes ---
    \node (stk) [draw]      at (0,0)        {\stks};% sticks, lower left
    \node (set) [draw, dst] at (3.5, 3.5)   {\drst};% upper right, styled


    % --- connecting with a sloped and styled text above ----
    \draw (stk) -- node [above, lbls] {label-text} (set);
    
    % --- connecting, with sloped and styled text below and a curved connector ---
    \draw [->] (stk) to [out=-30 , in=-100]% flexing the line
        node [below, lbls] {\brd} (set);
}

\end{document}
