# How to closed lines? \oval

How to close lines in this? I tried and failed!

\documentclass{article}

\begin{document}

\begin{picture}(50,50)
\put(22.5,7){\oval(3,2)[lt]}
\put(22.5,7){\oval(3,2)[bl]}
\put(22.5,7){\oval(3,2)[tr]}
\put(25,7){\oval(2,2)[b]}
\put(27.5,7){\oval(3,2)[rt]}
\put(27.5,7){\oval(3,2)[br]}
\put(27.5,7){\oval(3,2)[t]}
\put(25,4.5){\oval(2,3)[b]}
\put(25,4.5){\oval(2,3)[br]}
\put(25,4.5){\oval(2,3)[bl]}
\put(23,4){\oval(2,4)[tr]}
\put(27,4){\oval(2,4)[tl]}
\end{picture}
\end{document}


LaTeX warns

LaTeX Warning: \oval, \circle, or \line size unavailable on input line 10.


By default picture mode works by setting characters next to each other so can not make very small shapes that are smaller than the characters.

\usepackage{pict2e}


then the definitions are changed to use PDF drawing primitives so these restrictions are lifted.

Besides loading pict2e, you can add a couple of small segments to fill in the gaps.

\documentclass{article}
\usepackage{pict2e}

\begin{document}
A
\begin{picture}(9,5)
\put(2,4){\oval(3,2)[lt]}
\put(2,4){\oval(3,2)[bl]}
\put(2,4){\oval(3,2)[tr]}
\put(4.5,4){\oval(2,2)[b]}
\put(7,4){\oval(3,2)[rt]}
\put(7,4){\oval(3,2)[br]}
\put(7,4){\oval(3,2)[t]}
\put(4.5,1.5){\oval(2,3)[b]}
\put(4.5,1.5){\oval(2,3)[br]}
\put(4.5,1.5){\oval(2,3)[bl]}
\put(2.5,1){\oval(2,4)[tr]}
\put(6.5,1){\oval(2,4)[tl]}
\put(2,3){\line(1,0){0.5}}  % <---
\put(7,3){\line(-1,0){0.5}} % <---
\end{picture}

\end{document}


I reduced the size.
