Is there a way to change annotate.draw_text position other then center?

[shin616122]

Sorry, I am new to Python and Roboflow.
I used the code below that I found in one of the example projects to show the tracking object counts but I want to have the label to show in a different position other than the center.
Is it possible?

zone_polygon = (ZONE_POLYGON * np.array([frame_width, frame_height])).astype(int)
zone = sv.PolygonZone(polygon=zone_polygon, frame_resolution_wh=tuple([frame_width, frame_height]))
zone_annotator = sv.PolygonZoneAnnotator(
    zone=zone,
    color=sv.Color.red(),
    thickness=0,
    text_thickness=4,
    text_scale=2,
)

zone.trigger(detections=detections)
frame = zone_annotator.annotate(scene=frame)

hello @shin616122 👋 , thanks for taking interest in supervision. We are already planning for such feature. Also we are working on different Annotators which will be released soon. Stay updated for new features.

@SkalskiP , we already talked about similar feature.

Ok understood
Thank you for the respone

@hardikdava So. what about now, this feature is available now??

It is not implemented directly, but you can still do it quickly. You need to skip the annotator and do it yourself.

• This part is responsible for loading the image, defining the zone, running detection and triggering the zone.

  import cv2
  import numpy as np
  import supervision as sv
  from ultralytics import YOLO
  
  # define polygon vertices
  POLYGON = np.array([
      [100, 100],
      [300, 100],
      [300, 300],
      [100, 300]
  ])
  
  # load model
  model = YOLO('yolov8s.pt')
  
  # read image
  image = cv2.imread(...)
  
  # get loaded image resolution
  height, width = image.shape[:2]
  resolution_wh = (width, height)
  
  # initiate polygon zone
  polygon_zone = sv.PolygonZone(polygon=POLYGON, resolution_wh=resolution_wh)
  
  # run model inference
  result = model(image)[0]
  detections = sv.Detections.from_ultralytics(result)
  
  # trigger zone
  polygon_zone.trigger(detections=detections)

• This part is responsible for drawing the zone and the counter.

  # x = 50, y = 50 is the center of your counter
  text_anchor = sv.Point(x=50, 50)
  
  annotated_image = image.copy()
  
  # draw polygon zone
  annotated_image = sv.annotated_frame = sv.draw_polygon(
      scene=annotated_image,
      polygon=POLYGON,
      color=sv.Color.red()
  )
  
  # draw counter
  annotated_frame = sv.draw_text(
      scene=annotated_frame,
      text=str(polygon_zone.current_count),
      text_anchor=text_anchor,
      background_color=sv.Color.red(),
      text_color=sv.Color.white()
  )

Thank you a lot bro, I will try it 🙏

[SkalskiP]

Sure! Let me know how it went!

[blackksheep10]

why draw_polygon() is not defined ??

[SkalskiP]

It should be sv.draw_polygon
