Viewpoint.withLatLongScale constructor

Viewpoint.withLatLongScale(
  1. {required double latitude,
  2. required double longitude,
  3. required double scale}
)

Creates a viewpoint with latitude, longitude, and scale.

The spatial reference for the defined point is WGS84.

Parameters:

  • latitude — The latitude coordinate for the viewpoint. Negative values are south of the equator.
  • longitude — The longitude coordinate for the viewpoint. Negative values are west of the prime meridian.
  • scale — The ratio between a distance on the map and the corresponding distance on the ground.

Implementation

factory Viewpoint.withLatLongScale(
    {required double latitude,
    required double longitude,
    required double scale}) {
  _initializeArcGISEnvironmentIfNeeded();
  final handle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_Viewpoint_createWithLatLongScale(
        latitude, longitude, scale, errorHandler);
  });
  return Viewpoint._withHandle(handle);
}
