ArcCurve

ArcCurve is an arc-curve geometry class that extends Curve. It represents a curve generated as an arc or as a polyline approximation of an arc, commonly used for arc connections and flow visualizations.

import { ArcCurve } from "maptalks";

const arc = new ArcCurve([[100, 0], [101, 1]]);
layer.addGeometry(arc);

Constructor

new ArcCurve(coordinates, options?)

Parameters:

• coordinates — The array of coordinates defining the two endpoints of the arc.
• options — (Optional) Geometry options, see the options of Curve / LineString.

options

Name	Type	Description	Default
arcDegree	Number	The opening angle of the arc.	90

Methods

No class-specific methods; it inherits the methods of Curve.

Static Methods

• ArcCurve.fromJSON(json): ArcCurve — Creates an ArcCurve instance from a JSON object.
