我有以下用于生成图表的代码。如何像 IPE 一样使生成的 PDF 仅与图形一样大？
\documentclass[landscape]{article}
\usepackage{standalone}
\usepackage{pgf}
\usepackage{tikz}
\usetikzlibrary{arrows,automata}
\usepackage{graphicx}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsthm}
\begin{document}
\begin{figure}
\begin{tikzpicture}[>=stealth',shorten >=1pt,auto,node distance=3 cm,scale=1,transform shape,line width=0.25mm]
\node[initial,state,fill=green!20,initial text={},line width=0.25mm] (A) {$q_{000}$};
\node[state,accepting,fill=red!20,line width=0.25mm] (B) [right of=A] {$q_{100}$};
\node[state,fill=blue!20,line width=0.25mm] (C) [right of=B] {$q_{010}$};
\node[state,accepting,fill=red!20,line width=0.25mm] (D) [right of=C] {$q_{110}$};

\node[state,accepting,fill=red!20,line width=0.25mm] (H) [right of=G] {$q_{111}$};

答案1
删除figure环境，删除\usepackage{standalone}并更改为\documentclass{standalone}。
不相关的评论。
请注意，虽然它仍然有效，但该
arrows库已被弃用，取而代之的是arrows.meta。但这确实有不同的语法，请参阅手册。不推荐使用该
of=语法，而建议加载positioning库并说=of，请参阅PGF/TikZ 中“right of=”和“right=of”之间的区别\usepackage{tikz}也会加载pgf（这并不奇怪）和graphicx，因此加载后两个包是多余的。您没有使用此图中的任何包的功能ams，因此也可以将它们删除。在这种情况下，所有这些都
align=center实际上没有任何作用。就我个人而言，我会使用 eg
above left而不是xshiftand/oryshift。对于有许多具有相同选项的元素的情况，添加样式可以使事情变得更整洁且更容易更改。
