# Write to YAML
ifdo_object.save("path/to/ifdo.yaml")

Create image annotations

from datetime import datetime
from ifdo.models import ImageAnnotation, AnnotationCoordinate, AnnotationLabel

# Create a bounding box
coordinates = [
    AnnotationCoordinate(x=0, y=0),
    AnnotationCoordinate(x=1, y=0),
    AnnotationCoordinate(x=1, y=1),
    AnnotationCoordinate(x=0, y=1),
]

# Create a label for it
label = AnnotationLabel(id="fish", annotator="kevin", created_at=datetime.now(), confidence=0.9)

# Pack it into an annotation
annotation = ImageAnnotation(coordinates=coordinates, labels=[label], shape='rectangle')

# Print it as a dictionary
print(annotation.to_dict())

{
  'coordinates': [
    {'x': 0, 'y': 0}, 
    {'x': 1, 'y': 0}, 
    {'x': 1, 'y': 1}, 
    {'x': 0, 'y': 1}
  ], 
  'labels': [
    {
      'id': 'fish', 
      'annotator': 'kevin', 
      'created-at': datetime.datetime(2023, 2, 28, 16, 39, 46, 451290),
