tikzpicture 之外的 tikz 范围环境的替代方案

我有很多小的 tikz 图形，我都想缩小它们，所以我想把它们放在一个范围内，如下所示：

\documentclass{article}
\usepackage{tikz}
\begin{document}
    \begin{scope}[scale=0.3]
        \begin{tikzpicture}
%               Draw stuff in a small scale
        \end{tikzpicture}
        \begin{tikzpicture}
%               Draw more stuff in a small scale
        \end{tikzpicture}
    \end{scope}
    \begin{tikzpicture}
%           Draw stuff in normal scale again
    \end{tikzpicture}
\end{document}

但这不起作用，因为范围环境仅在 tikzpicture 内部定义。

我怎样才能实现这种效果？我是否必须使用\tikzset并保存当前比例，然后缩小比例并在最后再次恢复，或者是否有“正确”的方法来做到这一点？

我们可以用\tikzset{every picture/.style={scale=0.3}}它实现这个目的。我附上了一个示例和页面预览，其中缩放比例从 0.1 到 1.2，步长为 0.1，以演示其用法。

%! *latex tikz-scaling-a.tex
\documentclass[a4paper]{article}
\pagestyle{empty}
\usepackage{tikz}
\parindent=0pt
\addtolength{\textheight}{1in}
\begin{document}
\def\malpicture{% Picture is changing, the font is not...
  \begin{tikzpicture}[x=1cm, y=1cm]
    \draw[line width=2pt, ](0,0)--(5,2);
    \node at (1,1) {Hello World!};
  \end{tikzpicture}
  }% End of \malpicture...
% A typical use... 
\malpicture\par
% And now with scaling...
\foreach\scaling in {0.1,0.2,...,1.2} {%
  \tikzset{every picture/.style={scale=\scaling}}% =0.3 etc.
  \fbox{\malpicture}\par
  }% End of \foreach\scaling...

\tikzset{every picture/.style={scale=0.3}}
\malpicture
\end{document}

我附上了一个类似的例子，其中使用TeX 组（括号或\begingroup和）来限制命令。第一张和最后一张图片没有变化，第二张和第三张受到命令的影响。\endgroup\tikzset\tikzset

%! *latex tikz-scaling-b.tex
\documentclass[a4paper]{article}
\pagestyle{empty}
\usepackage{tikz}
\parindent=0pt
\addtolength{\textheight}{1in}
\begin{document}

% A normal picture before a change is applied... 
\begin{tikzpicture}[x=1cm, y=1cm]
    \draw[line width=2pt, ](0,0)--(5,2);
    \node at (1,1) {Hello World!};
\end{tikzpicture}

% A group will limit the \tikzset command...
\begingroup % or we use opening brace "{"
\tikzset{every picture/.style={scale=0.3}} % a change in parameters
\begin{tikzpicture}[x=1cm, y=1cm]
    \draw[line width=2pt, ](0,0)--(5,2);
    \node at (1,1) {My first scaled picture!};
\end{tikzpicture}\par
\begin{tikzpicture}[x=1cm, y=1cm]
    \draw[line width=2pt, ](0,0)--(5,2);
    \node at (1,1) {My second scaled picture!};
\end{tikzpicture}%
\endgroup % or we use closing brace "}"

% A let's get back to normal scaling... 
\begin{tikzpicture}[x=1cm, y=1cm]
    \draw[line width=2pt, ](0,0)--(5,2);
    \node at (1,1) {My last picture!};
\end{tikzpicture}
\end{document}
