retrieveLabels method

@override Future<JobResult> retrieveLabels(JobRequest jobRequest)

Retrieves labels for separate rendering to support map rotation.

For rotation-enabled maps, labels are rendered separately from the base map to prevent text distortion. This method extracts label information that can be rendered dynamically with proper orientation.

jobRequest Request containing tile coordinates and rendering parameters Returns JobResult with label rendering instructions

Implementation

@override
Future<JobResult> retrieveLabels(JobRequest jobRequest) async {
  JobResult result = await _isolateInstance.compute(_RendererRetrieveLabelsRequest(jobRequest));
  return result;
}
