get Font Size in Python with Tesseract and Pyocr

Question

Is it possible to get font size from an image using pyocr or Tesseract? Below is my code.

tools = pyocr.get_available_tools()
tool = tools[0]
txt = tool.image_to_string(
      Imagee.open(io.BytesIO(req_image)),
      lang=lang,
      builder=pyocr.builders.TextBuilder()
)

Here i get text from image using function image_to_string . And now, my question is, if i can get font-size(number) too of my text.

Try amending your sample code to be [mcve]. – boardrider Sep 05 '16 at 14:05 — boardrider, Sep 05 '16 at 14:05

Using tesserocr, you can get a ResultIterator after calling Recognize on your image, for which you can call the WordFontAttributes method to get the information you need. Read the method's documentation for more info.

import io
import tesserocr
from PIL import Image

with tesserocr.PyTessBaseAPI() as api:
    image = Image.open(io.BytesIO(req_image))
    api.SetImage(image)
    api.Recognize()  # required to get result from the next line
    iterator = api.GetIterator()
    print iterator.WordFontAttributes()

Example output:

{'bold': False,
 'font_id': 283,
 'font_name': u'Times_New_Roman',
 'italic': False,
 'monospace': False,
 'pointsize': 9,
 'serif': True,
 'smallcaps': False,
 'underlined': False}

It looks like this no longer works, sadly :/ https://github.com/tesseract-ocr/tesseract/issues/1074 — Inaimathi, Sep 20 '18 at 16:20
Though this is old, the method only works in Tesseract 3.0.5 — ken4ward, Jan 11 '22 at 11:51
