使用 [记住图片，覆盖] 时出现错误“未定义的控制序列”

Question

tikzpicture我在另一个里面使用了两个tikzpicture。我想从一张图片画一个箭头指向另一张图片。为此，我使用了[remember picture, overlay]如下代码所示的属性。

新代码

\pgfdeclarelayer{background}
\pgfdeclarelayer{above_background}
\pgfdeclarelayer{main}
\pgfsetlayers{background,above_background,main}

\begin{center}
\begin{tikzpicture}[remember picture, overlay]
    \begin{pgfonlayer}{background}
        \node[cloud, cloud puffs=16, minimum width=8cm, minimum height=3cm, draw] (cloud) at (0,0) {};
    \end{pgfonlayer}    

    \node[] {
        \begin{tikzpicture}[auto]

            \node[draw] (node1) at (0,0) {Node 1};
            \node[draw] (node2) at (0,-1.5) {Node 2};
            \node[draw] (node3) at (0,-3) {Node 3};
            \node[draw] (node4)  at (0,-4.5) {Node 4};

            \begin{pgfonlayer}{main}
                \path (node1.west |- node1.north)+(-0.3,0.8) node (a) {};
                \path (node4.south -| node4.east)+(2.5,-1) node (b) {};
                \path[fill=yellow!20,rounded corners, draw=black!50, dashed]
                (a) rectangle (b);
            \end{pgfonlayer}

            \begin{pgfonlayer}{above_background}
                \path (node1.west |- node1.north)+(-0.5,1) node (a) {};
                \path (node4.south -| node4.east)+(1.2,-1.5) node (b) {};
                \path[fill=black!10,rounded corners, draw=black!50,dashdotted]
                (a) rectangle (b);
            \end{pgfonlayer}


        \end{tikzpicture}
        \hspace{1cm}
        \begin{tikzpicture}[auto]

            \node[draw] (node5) at (0,0) {Node 5};
            \node[draw] (node6) at (0,-1.5) {Node 6};
            \node[draw] (node7) at (0,-3) {Node 7};
            \node[draw] (node8)  at (0,-4.5) {Node 8};

            \begin{pgfonlayer}{main}
                \path (node5.west |- node5.north)+(-0.3,0.8) node (a) {};
                \path (node8.south -| node8.east)+(2.5,-1) node (b) {};
                \path[fill=yellow!20,rounded corners, draw=black!50, dashed]
                (a) rectangle (b);
            \end{pgfonlayer}

            \begin{pgfonlayer}{above_background}
                \path (node5.west |- node5.north)+(-0.5,1) node (a) {};
                \path (node8.south -| node8.east)+(1.2,-1.5) node (b) {};
                \path[fill=black!10,rounded corners, draw=black!50,dashdotted]
                (a) rectangle (b);
            \end{pgfonlayer}


            \draw[->,draw=black] (node5) to (node1);

        \end{tikzpicture}
    };
\end{tikzpicture}
\end{center}

旧代码

\begin{center}
    \begin{tikzpicture}[remember picture, overlay]
        \node[] {
        \begin{tikzpicture}[auto]

            \node[draw] (node1) at (0,0) {Node 1};

        \end{tikzpicture}
        \hspace{1cm}
        \begin{tikzpicture}[auto]

            \node[draw] (node2) at (2,2) {Node 2};

            \draw[->,draw=black] (node2) to (node1);

        \end{tikzpicture}
    };
\end{tikzpicture}
\end{center}

当我编译上面的图片时，我得到了以下错误技术中心并且还特克斯工作室

!Undefined control sequence.
1.61 \savepicturepage
                {pgfid2}{15}

我尝试删除 .aux 文件并再次重新编译它，但问题仍然存在。

你为什么要把事情弄复杂？你所需要的可以用更简单的方法实现。

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[remember picture, overlay,auto]
  \node[draw] (node1) at (0,0) {Node 1};
  \node[draw] (node2) at (3,2) {Node 2};  %% instead of hspace, I used 3 as x-coordinate.
  \draw[->,draw=black] (node2) to (node1);
\end{tikzpicture}
%Some text here whose position won't be affected by the \verb|{tikzpicture}|.
\end{document}

remember picture此外，如果您不使用诸如current page.north east等坐标，则无需使用。

进一步减少复杂性，以下是代码：

\documentclass[a4paper,10pt]{report}
\usepackage{tikz}
\begin{document}

\usetikzlibrary{calc, shapes, backgrounds, arrows, decorations.pathmorphing, positioning, fit, petri, tikzmark}

\pgfdeclarelayer{cloud}
\pgfdeclarelayer{background}
\pgfdeclarelayer{above_background}
\pgfdeclarelayer{main}
\pgfsetlayers{cloud,background,above_background,main}

\tikzset{component/.style={draw, fill=blue!20, text width=5em,
    text centered, minimum height=2.5em}}

\begin{center}
\begin{tikzpicture}%[remember picture, overlay]
    \node[draw] (node1) [component] at (0,0) {Node 1};
    \node[draw] (node2) [component] at (0,-1.5) {Node 2};
    \node[draw] (node3) [component] at (0,-3) {Node 3};
    \node[draw] (node4) [component]  at (0,-4.5) {Node 4};

    \node[draw,right=5cm of node1] (node5) [component]  {Node 5};
    \node[draw,right=5cm of node2] (node6) [component]  {Node 6};
    \node[draw,right=5cm of node3] (node7) [component]  {Node 7};
    \node[draw,right=5cm of node4] (node8) [component]  {Node 8};

    \begin{pgfonlayer}{above_background}
       \node[fill=yellow!20,rounded corners, draw=black!50, dashed,fit=(node1)(node4),
         inner sep=10pt]  (left1)  {};
       \node[fill=yellow!20,rounded corners, draw=black!50, dashed,fit=(node5)(node8),
         inner sep=10pt]  (right1)  {};
    \end{pgfonlayer}

    \begin{pgfonlayer}{background}
       \node[fill=black!10,rounded corners, draw=black!50,dashdotted,fit=(left1),
             inner sep=10pt]  (left2)  {};
       \node[fill=black!10,rounded corners, draw=black!50,dashdotted,fit=(right1),
             inner sep=10pt]  (right2)  {};
    \end{pgfonlayer}

    %% this is also possible
%    \begin{pgfonlayer}{cloud}
%        \node[cloud, cloud puffs=16,fit=(node1)(node8), draw] (cloud) {};
%    \end{pgfonlayer}
%% or this
    \begin{pgfonlayer}{cloud}
        \node[cloud, cloud puffs=16,minimum width=14cm, minimum height=8cm, draw] (cloud)
            at ($(left2)!0.5!(right2)$)  {};
    \end{pgfonlayer}

    \draw[->,draw=black] (node5) to (node1);

\end{tikzpicture}
\end{center}
\end{document}
