Filter

A Filter is a function to control whether an annotation should be made visible or not. The function receives the ImageAnnotation as an input argument and must return a boolean value: true if the annotation should be visible, false otherwise.

You can set the filter on your annotator instance via the setFilter method.

anno.setFilter((annotation) => {
  // Get the first 'tagging' body
  const label = annotation.bodies.find(b => b.purpose === 'tagging')?.value;

  // Display the annotation is the first tag is 'important'
  return label === 'important';
});
