AnnotationState

Represents the current state of an annotation in the user interface. The AnnotationState is passed to dynamic style functions as an argument.

Example

anno.setStyle((annotation, state) => {
  if (state.selected) {
    return {
      fill: '#ff0000',
      fillOpacity: 0.3,
      stroke: '#ff0000',
      strokeOpacity: 1
    };
  }

  // Default style for non-selected annotations
  return {
    fill: '#00ff00',
    fillOpacity: 0.2,
    stroke: '#00ff00',
    strokeOpacity: 1
  };
});
