# fxpicture

Line styles for LaTeX's `picture` environment.

`fxpicture` builds on [pict2e](https://ctan.org/pkg/pict2e) and adds two declarations:

```latex
\linestyle{solid}   \linestyle{dashed}   \linestyle{dotted}   \linestyle{dashdot}
\dashpattern{3pt}{2pt}
```

Like `\linethickness`, they last until the end of the group, and they apply to every line pict2e
strokes: `\line`, `\vector`, `\Line`, `\polyline`, `\polygon`, `\circle`, `\oval`, `\arc`,
`\qbezier`, `\cbezier` and `\strokepath`.

```latex
\usepackage{fxpicture}
...
\begin{picture}(60,40)
  {\linestyle{dashed}
    \put(10,10){\line(1,0){40}}
    \put(10,20){\oval(40,10)}
    \put(10,30){\qbezier(0,0)(20,15)(40,0)}
  }
\end{picture}
```

It works with each of pict2e's drivers: pdfTeX, LuaTeX, XeTeX, dvips and dvipdfm(x).
