The ScaleControl object is used to configure the Scale control on the map.

The ScaleControl object lets you enable or disable the Scale control. By default it is disabled.

Example usage

const scaleControl = G.scaleControl({
    enabled: true
});

const map = G.map('map', {
    center: [40.7128, -74.0060],
    scaleControl: scaleControl,
});

Creating the ScaleControl object

G.scaleControl(options?: ScaleControlValue): ScaleControl

There are a few ways to setup the ScaleControl object.
