DESCRIPTION Draws curves in the LaTeX 2e picture environment using parabolic arcs between data points with continuous slope at joins. For circles and circular arcs uses up to 16 parabolic arcs. Also draws symbols or dash patterns along curves. A straight side switch changes curves to polygons. Extends picture capability without extra programs and data files. Parabolic arcs consist of short chords drawn by overlapping disks or line drawing `\special's selected by package options. INSTALLATION If your LaTeX system is comprehensive curves.sty may already be installed. Download `curves.dtx' and run $ latex curves.dtx If you get the error message: ! LaTeX Error: File `curves.sty' not found. curves is not installed. If you get messages about `\straighttrue' undefined you need to upgrade `curves.sty'. If LaTeX stops processing with anything else press `S' then `Enter'. Use the following if you wish to install or upgrade `curves.sty'. Download `curves.ins' and run $ latex curves.ins which will generate `curves.sty' and `curvesls.sty' from `curves.dtx'. To install curves you need to put `curves.sty' on your TeX search path as root or administrator and run `mktexlsr' or equivalent to update the TeX file databases. USE Download and read `curves.pdf' for instructions and simple examples.

## curves – Curves for LaTeX picture environment

This package draws curves in the standard LaTeX picture environment using parabolas between data points with continuous slope at joins; for circles and arcs, it uses up to 16 parabolas. The package can also draw symbols or dash patterns along curves.

The package provides facilities equivalent to technical pens with
compasses and French curves. Curves consist of short secants
drawn by overlapping disks or line-drawing `\special` commands
selected by package options.
