带有叠加图钉的 TikZ 图像

在下面的 TikZ 图像中，我希望两个大头针不延伸边界框，但仍能完整显示（即使它们的一部分落在边界框之外）。

在此处输入图片描述

使用overlay节点或引脚本身的选项（如 percusse 在评论中所建议的这个答案) 不幸地将引脚裁剪到边界框中。如果我们将节点封闭在pgfinterruptboundingbox或scope环境中（后者再次使用选项overlay），情况也是如此。

\documentclass[tikz]{standalone}

\usetikzlibrary{patterns}

\tikzset{
    cross/.style={path picture={\draw[black]
        (path picture bounding box.south east) -- (path picture bounding box.north west)
        (path picture bounding box.south west) -- (path picture bounding box.north east);}}
}

\begin{document}
\begin{tikzpicture}

    % Loop
    \def\radius{1.5}
    \draw[very thick] (0,0) circle (\radius);
    \draw[fill=white,cross] (0,\radius) circle (0.175*\radius) node[above=5pt] {$\partial_k R_{k,ij}(p_1,p_2)$};
    \node at (-1.35*\radius,0.75*\radius) {$G_{ij}(p_1,p_2)$};
    \node at (1.35*\radius,0.75*\radius) {$G_{jk}(p_2,p_3)$};
    \node[below] at (0,-\radius) {$G_{ef}(p_3,p_4)$};

    % External lines
    \draw (-2*\radius,0) -- (-\radius,0) node[pos=0.4,below] {$\varphi_a$};
    \draw[->,semithick,yshift=5pt,shorten >=5pt,shorten <=5pt] (-2*\radius,0) -- (-1.25*\radius,0) node[midway,above] {$q_1$};
    \draw (\radius,0) -- (2*\radius,0) node[pos=0.6,below] {$\varphi_b$};
    \draw[->,semithick,yshift=5pt,shorten >=5pt,shorten <=5pt] (1.25*\radius,0) -- (2*\radius,0) node[midway,above] {$q_2$};

    % Vertices
    \node[draw,circle,minimum size=16pt,fill=white,postaction={pattern=north east lines},pin={260:$\Gamma_{k,ail}^{(3)}(q_1,\!p_1,\!p_4\!)$}] at (-\radius,0) {};
    \node[draw,circle,minimum size=16pt,fill=white,postaction={pattern=north east lines},pin={280:$\Gamma_{k,bde}^{(3)}(q_2,\!p_3,\!p_4\!)$}] at (\radius,0) {};

答案1

如果pin没有产生您想要的结果，请不要使用它并寻找替代方案。这是一个，两个独立的节点，Gamma ...字体较小，两条线将它们连接到圆圈，如pin。

注意：可能pin产生类似的结果，但我现在不想查阅文档。

这显示了如何创建部分重叠的图像。 的问题在于\includestandalone您无法直接传递\leftoverlap和\rightoverlap值。您可以将它们写出来并手动输入。您也可以将它们写入文件并再次读入。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{patterns}

\newlength{\leftoverlap}
\newlength{\rightoverlap}

\tikzset{
    cross/.style={path picture={\draw[black]
        (path picture bounding box.south east) -- (path picture bounding box.north west)
        (path picture bounding box.south west) -- (path picture bounding box.north east);}}
}

\begin{document}

\sbox0{\begin{tikzpicture}
    % Loop
    \def\radius{1.5}
    \draw[very thick] (0,0) circle (\radius);
    \draw[fill=white,cross] (0,\radius) circle (0.175*\radius) node[above=5pt] {$\partial_k R_{k,ij}(p_1,p_2)$};
    \node at (-1.35*\radius,0.75*\radius) {$G_{ij}(p_1,p_2)$};
    \node at (1.35*\radius,0.75*\radius) {$G_{jk}(p_2,p_3)$};
    \node[below] at (0,-\radius) {$G_{ef}(p_3,p_4)$};

    % External lines
    \draw (-2*\radius,0) -- (-\radius,0) node[pos=0.4,below] {$\varphi_a$};
    \draw[->,semithick,yshift=5pt,shorten >=5pt,shorten <=5pt] (-2*\radius,0) -- (-1.25*\radius,0) node[midway,above] {$q_1$};
    \draw (\radius,0) -- (2*\radius,0) node[pos=0.6,below] {$\varphi_b$};
    \draw[->,semithick,yshift=5pt,shorten >=5pt,shorten <=5pt] (1.25*\radius,0) -- (2*\radius,0) node[midway,above] {$q_2$};

    % Vertices
    \node[draw,circle,minimum size=16pt,fill=white,postaction={pattern=north east lines},pin={260:$\Gamma_{k,ail}^{(3)}(q_1,\!p_1,\!p_4\!)$}] at (-\radius,0) {};
    \node[draw,circle,minimum size=16pt,fill=white,postaction={pattern=north east lines},pin={280:$\Gamma_{k,bde}^{(3)}(q_2,\!p_3,\!p_4\!)$}] at (\radius,0) {};

    % compute margins
    \coordinate(A) at (-2*\radius,0);
    \coordinate(B) at (2*\radius,0);
    \pgfextractx{\leftoverlap}{\pgfpointdiff{\pgfpointanchor{current bounding box}{west}}{\pgfpointanchor{A}{center}}}
    \pgfextractx{\rightoverlap}{\pgfpointdiff{\pgfpointanchor{B}{center}}{\pgfpointanchor{current bounding box}{east}}}
    \global\leftoverlap=\leftoverlap
    \global\rightoverlap=\rightoverlap

\end{tikzpicture}}%
\fboxsep=0pt
\fbox{% show minipage border
\begin{minipage}{\dimexpr \wd0-\leftoverlap-\rightoverlap}
\leftskip=-\leftoverlap
\rightskip=-\rightoverlap
\usebox0
\end{minipage}}
\end{document}
