中国十二生肖和农历年可以说是非常亲密的朋友。在东方文化中，每个农历年都分配给十二生肖中的一种动物。今年的动物（或者说吉祥物）是猪。所以，我在这个问题中的问题是：
如何用 LaTeX 画一只（可爱的）小猪？
我在TeXample上找到了一张非常漂亮的图：

% This code can/should be improved by using the pgfkey library.

% We're not using pgfkeys, and we've chosen to use keyval

% with predefined colours for certain parts and predefined
% scaling factors for line thickness.

不过，我希望在这里看到更多的猪，尤其是和其他熟悉的动物一起，比如狮子、鸭子、土拨鼠、熊、兔子、鸟、驴或企鹅。
我也在寻找tikzlings猪！

首次亮相tikzpig：

同时，tikzpig已添加到软件包的开发版本中tikzlings（可用这里) 改进了@Circumscribe和@CarLaTeX（多谢！）
\documentclass{standalone}
\usepackage{tikzlings}
\begin{document}
\begin{tikzpicture}
\pig

答案2
你真的不需要任何包
\documentclass{article}
\begin{document}
\begin{picture}(100,100)
\put(43,56){\circle{6}}
\put(43,56){\circle*{1}}
\put(57,56){\circle{6}}
\put(57,56){\circle*{1}}
\put(50,45){\circle{12}}
\put(48,45){\oval(3,5)}
\put(52,45){\oval(3,5)}
\put(50,50){\circle{40}}
\put(43,32){\oval(5,20)[b]}
\put(57,32){\oval(5,20)[b]}
\put(64,64){\vector(1,1){10}}
\end{picture}
\end{document}
答案3
为了完整起见，我们来选择 Unicode 猪！
% arara: xelatex
\documentclass{standalone}
\usepackage{fontspec}
\usepackage{graphicx}
\setmainfont{Symbola}
\begin{document}
\scalebox{10}{\char"1F416}
\end{document}
答案4
运行xelatex
\documentclass[pstricks]{standalone}
\usepackage{pst-fun}
\begin{document}
\begin{pspicture}(-2,-4)(8,4)
\psPig(0,0)
\psPig[fillcolor=blue!40,noseColor=purple,eyeColor=red,linewidth=4pt,unit=2](4,0)
\end{pspicture}
\end{document}
