Scale
âš The Scale plugin is currently meant for passive usage only. It's API has not yet been finally defined, and is subject to change without further notice.
Scope
The scale plugin shows the current map resolution as relative scale (1:x) and/or absolute scale (a drawn line has length x units).
Configuration
scale
| fieldName | type | description |
|---|---|---|
| showScaleSwitcher | boolean? | If set to true, a button to switch to a specific scale will be rendered. Defaults to false. Requires the configuration parameter options set in the mapConfiguration, see <...masterportalAPI.fields> in the @polar/core package documentation for more information. Also requires the parameter zoomMethod to be configured. |
| zoomMethod | string? | Path to the action that is used for the zoom of the scale switcher. Has to take zoomLevel as payload. Must be configured for the scale switcher, otherwise it will not be rendered. |
For details on the displayComponent attribute, refer to the Global Plugin Parameters section of @polar/core.
Example configuration:
scale: {
showScaleSwitcher: true,
zoomMethod: 'plugin/zoom/setZoomLevel'
}
