mapbox-gl-draw-rounded-circle

We have forked the custom draw circle mode to fix the issues and add some features (see Changelog below):

* forked repo on Github: https://github.com/iamanvesh/mapbox-gl-draw-circle
* published package on NPM: https://www.npmjs.com/package/mapbox-gl-draw-rounded-circle

Usage

$3

``
npm install mapbox-gl-draw-rounded-circle
`

`
import {
CircleMode,
DragCircleMode,
DirectMode,
SimpleSelectMode
} from 'mapbox-gl-draw-rounded-circle';


// userProperties has to be enabled
const draw = new MapboxDraw({
defaultMode: "draw_circle",
userProperties: true,
modes: {
...MapboxDraw.modes,
draw_circle : CircleMode,
drag_circle : DragCircleMode,
direct_select: DirectMode,
simple_select: SimpleSelectMode
}
});

// Add this draw object to the map when map loads
map.addControl(draw);
`

The default radius units are in kilometers and initial radius is 2km.

`
// Provide the default radius as an option to CircleMode
draw.changeMode('draw_circle', { initialRadiusInKm: 0.5 });
`

It fires the same events as the mapbox-gl-draw library. For more information follow this link.
