draw_ocr_infos(img: np.ndarray, texts: List[str], polygons: Polygons, colors: tuple = None, concat_axis: int = 1, thicknesses: int = 2, font_path: str = None) -> np.ndarray

• Description

  Draw OCR (Optical Character Recognition) results on an image.

• Parameters

  • img (np.ndarray): The image to draw on.
  • texts (List[str]): List of detected text strings.
  • polygons (D.Polygons): List of polygons representing the detected text boundaries.
  • colors (tuple): RGB values of the colors to draw. If not provided, a unique color is generated for each text based on a fixed logic.
  • concat_axis (int): The axis used to concatenate the original image and the annotated image. Defaults to 1 (horizontal).
  • thicknesses (int): The thickness of the polygons to draw. Defaults to 2.
  • font_path (str): Path to the font file to use. If not provided, the default font "NotoSansMonoCJKtc-VF.ttf" is used.

• Returns

  • np.ndarray: The image concatenated with the annotated image.

• Example

  import docsaidkit as D
  
  img = D.imread('lena.png')
  texts = ['Hello!', 'Test!']
  polygons = [
      D.Polygon([(20, 20), (100, 20), (80, 80), (20, 40)]),
      D.Polygon([(100, 200), (20, 200), (40, 140), (100, 180)])
  ]
  ocr_img = D.draw_ocr_infos(img, texts, polygons, concat_axis=1, thicknesses=2)
