WordFontAttributes does not detect bold

[IKetchup]

I working on a project where I would like to find bold text in an image (medical repport).

For this Im using WordFontAttributes trhough the following function:

def get_words_info(image_path, tessdata_path):
    """
    get path to image and path to tessdata and return dict with info about each word
    """
    api = PyTessBaseAPI(path=tessdata_path)
    with PyTessBaseAPI(path=tessdata_path) as api:
        api.SetImageFile(image_path)
        api.Recognize()
        iter = api.GetIterator()
        level = RIL.WORD

        result = []

        for r in iterate_level(iter, level):
            element = r.GetUTF8Text(level)
            word_attributes = r.WordFontAttributes()
            base_line = r.BoundingBox(level)
            print(base_line)

            if element:
                word_attributes['word'] = element
                word_attributes['position'] = base_line

            result.append(word_attributes)

        return result

I tried this bold detection on several images on jpg format. For some the bold text is detected nicely but for some other like the picture bellow the bold text is not detected (bold boolean to false in the resust)

here is the exemple for the doctor name in bold at the bottom right :

  'bold': False,
  'italic': False,
  'underlined': False,
  'monospace': False,
  'serif': True,
  'smallcaps': False,
  'pointsize': 9,
  'font_id': 283,
  'word': 'BERTHELEN',
  'position': (1696, 2518, 1979, 2549)},

Does someone know why the bold detection is not consistent ?

Thanks

Hey, can you tell which version are you using?
