Arc

eps_type: eps_arc

The arc definition here handles arcs, including those with different primary and secondary axis values. EPS arc features are linear features used to specify elliptical arcs. As such, the feature definition for eps_arc is similar to the ellipse definition with two additional angles to control the portion of the ellipse boundary drawn. EPS arcs also support rotation.

Tip: The ArcStroker transformer can be used to convert an arc to a linestring. This is useful for storing arcs in systems that do not support them directly.

In addition to the attributes below, arcs also make use of the pen attributes as defined for eps_area since arcs can also have fills.
