我正在尝试使用该命令从 Tikz 内容创建一个图像文件pdflatex。
以下是 Tikz 内容：
\begin{document}
\usepackage{tikz}
\usetikzlibrary{automata, positioning, arrows, shapes}
\tikzset{
box/.style = {draw, rectangle, minimum height = 2.5em, minimum width = 2.5em},
circl/.style = {draw, circle, minimum size = 8mm,label={[font=\small, inner sep=1pt]200:$+$}},
input/.style = {coordinate},
output/.style = {coordinate},
to/.style = {->,>=stealth', shorten >=1pt, semithick, font=\small}
}
\begin{tikzpicture}
\draw (0,0) -- (4,0);
\end{tikzpicture}
\end{document}
我使用以下命令：
$ pdflatex figure.tex
执行成功结束但是pdf文件是空的。
我正在使用 Linux Mint 并安装了 Textlive：
ii texlive 2015.20160320-1ubuntu0.1 all TeX Live: A decent selection of the TeX Live packages
ii texlive-base 2015.20160320-1ubuntu0.1 all TeX Live: Essential programs and files
ii texlive-binaries 2015.20160222.37495-1ubuntu0.1 amd64 Binaries for TeX Live

ii texlive-pictures 2015.20160320-1ubuntu0.1 all TeX Live: Graphics, pictures, diagrams
我做错了什么？
谢谢你的帮助！Thierry

文档不完整，无法成功编译。至少缺少一个文档类，并且包应该位于序言中，而不是文档正文中：
\documentclass[margin=3mm,convert]{standalone}
\usepackage{tikz}
\usetikzlibrary{automata, positioning, arrows, shapes}
\tikzset{
box/.style = {draw, rectangle, minimum height = 2.5em, minimum width = 2.5em},
circl/.style = {draw, circle, minimum size = 8mm,label={[font=\small, inner sep=1pt]200:$+$}},
input/.style = {coordinate},
output/.style = {coordinate},
to/.style = {->,>=stealth', shorten >=1pt, semithick, font=\small}
}
\begin{document}
\begin{tikzpicture}
\draw (0,0) -- (4,0);
\end{tikzpicture}
\end{document}
