如何在“tikzpicture”内模仿“tikzpicture”（或者如何将“tikzpicture”放入节点）？

我将整个文档排版在一个单独的 中tikzpicture，这意味着文档中的文本块由 表示\path node{...};。但是，如果不使用额外的tikzpicture环境，当必须将图形插入文档时，情况会变得复杂。tikzpicture但是，使用额外的 会产生难以处理的垂直间距（并且会破坏框架框，即background rectange周围tikzpiture）。我该如何解决这个问题？我们能否以某种方式使用范围并为其分配样式，以便它可以“模仿” tikzpicture？我需要能够轻松定位和缩放整个绘图，而不是单独处理绘图的每个路径（以将其调整为上面的文本）。它还会造成将文本定位在绘图之后的问题，因为文本需要与某个东西对齐：您不能将节点与非节点的路径对齐，并且绘图主要由非节点的路径组成（将文本定位到绘图的容器中会很容易，但没有这样的容器）。

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
  \begin{tikzpicture}
    \path node[anchor=north west,text width=50mm](n1){This is sentence 1. This is sentence 2. This is sentence 3.};
    \path node[anchor=north west,text width=50mm]at(n1.south west){\[2+2=4\]};

    % following drawing should behave as a picture
    %  so that it can be easily moved and scaled
    \path node[anchor=north west](t1){DRAWING TITLE};
    \path[draw,radius=30pt]($(t1.south)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(-15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,line width=1pt]($(t1.south)+(0,0)+(0,-30pt)$)--($(t1.south)+(0,10pt)+(0,-30pt)$);
    \path[draw]($(t1.south)+(-10pt,-15pt)+(0,-30pt)$)rectangle($(t1.south)+(10pt,-5pt)+(0,-30pt)$);
    \path node[font=\tiny]at($(t1.south)+(0,-40pt)$){text};
  \end{tikzpicture}
\end{document}

遵循半工作，但输出中未突出显示的其他问题：（1）tikzpicture由于第二个tikzpicture环境导致的额外垂直间距（如果所有内容都在单个内，则完全可以控制），（2）varwidth环境的使用和（结果）节点的剪切（在右侧）。

\documentclass[varwidth=50mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
  \begin{tikzpicture}
    \path node[anchor=north west,text width=50mm](n1){This is sentence 1. This is sentence 2. This is sentence 3.};
    \path node[anchor=north west,text width=50mm]at(n1.south west){\[2+2=4\]};
  \end{tikzpicture}\par
  \begin{tikzpicture}[text width=50mm,align=center]
    \path node[anchor=north west](t1){DRAWING TITLE};
    \path[draw,radius=30pt]($(t1.south)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(-15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,line width=1pt]($(t1.south)+(0,0)+(0,-30pt)$)--($(t1.south)+(0,10pt)+(0,-30pt)$);
    \path[draw]($(t1.south)+(-10pt,-15pt)+(0,-30pt)$)rectangle($(t1.south)+(10pt,-5pt)+(0,-30pt)$);
    \path node[font=\tiny]at($(t1.south)+(0,-40pt)$){text};
  \end{tikzpicture}
\end{document}

Answer 1

您可以使用scope带有该local bounding box选项的环境吗？

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
  \begin{tikzpicture}
    \path node[anchor=north west,text width=50mm](n1){This is sentence 1. This is sentence 2. This is sentence 3.};
    \path node[anchor=north west,text width=50mm]at(n1.south west){\[2+2=4\]};

    % following drawing should behave as a picture
    %  so that it can be easily moved and scaled
    \begin{scope}[
       shift={(0,-3)},
       scale=0.7,
       local bounding box=smiley
       ]
    \path node[anchor=north west](t1){DRAWING TITLE};
    \path[draw,radius=30pt]($(t1.south)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(-15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,radius=5pt]($(t1.south)+(15pt,10pt)+(0,-30pt)$)circle;
    \path[draw,line width=1pt]($(t1.south)+(0,0)+(0,-30pt)$)--($(t1.south)+(0,10pt)+(0,-30pt)$);
    \path[draw]($(t1.south)+(-10pt,-15pt)+(0,-30pt)$)rectangle($(t1.south)+(10pt,-5pt)+(0,-30pt)$);
    \path node[font=\tiny]at($(t1.south)+(0,-40pt)$){text};
    \end{scope}

    \draw [red] (smiley.north west) to[bend left] (smiley.north east);

    \node [right] at (smiley.east) {foo};
  \end{tikzpicture}
\end{document}
