draw_polygon

draw_polygon(img: np.ndarray, polygon: _Polygon, color: _Color = (0, 255, 0), thickness: _Thickness = 2, fillup: bool = False, **kwargs) -> np.ndarray

• Dependencies

  • Install capybara-docsaid[visualization] first.

• Description: Draws a polygon on an image.

• Parameters

  • img (np.ndarray): The image to draw on, as a NumPy array.
  • polygon (Union[Polygon, np.ndarray]): The polygon to draw, either as a Polygon object or a NumPy array in the format [[x1, y1], [x2, y2], ...].
  • color (_Color): Polygon color (BGR). Default is (0, 255, 0).
  • thickness (_Thickness): Line thickness. Default is 2.
  • fillup (bool): Whether to fill the polygon. Defaults to False.
  • kwargs: Other parameters.

• Returns

  • np.ndarray: The image with the polygon drawn on it.

• Example

  from capybara import Polygon, imread
  from capybara.vision.visualization.draw import draw_polygon
  
  img = imread('lena.png')
  polygon = Polygon([(20, 20), (100, 20), (80, 80), (20, 40)])
  polygon_img = draw_polygon(img, polygon, color=(0, 255, 0), thickness=2)
