[python][자료구조] "pdf 취소선 검출"  How to identify strike-out text from PDF files using Python

I would like to extract only the strike-out text from a .pdf file. I have tried the below code, it is working with a sample pdf file I have. But it is not working with another pdf file which I think is a scanned one. Is there any standard way to extract only strike-out text from a pdf file using python? Any help would be really appreciated.

This is the code I was using:

from pydoc import doc
from pdf2docx import parse
from typing import Tuple
from docx import Document

def convert_pdf2docx(input_file: str, output_file: str, pages: Tuple = None):
    """Converts pdf to docx"""
    if pages:
        pages = [int(i) for i in list(pages) if i.isnumeric()]
    result = parse(pdf_file=input_file,
                   docx_with_path=output_file, pages=pages)
    summary = {
        "File": input_file, "Pages": str(pages), "Output File": output_file
    }

if __name__ == "__main__":
    pdf_file = 'D:/AWS practice/sample_striken_out.pdf'
    doc_file = 'D:/AWS practice/sample_striken_out.docx'
    convert_pdf2docx(pdf_file, doc_file)
    document = Document(doc_file)
    with open('D:/AWS practice/sample_striken_out.txt', 'w') as f:
        for p in document.paragraphs:
            for run in p.runs:
                if not run.font.strike:
                    f.write(run.text)
                    print(run.text)
            f.write('\n')

Note: I am converting PDF to DOCX first and then trying to identify the strike-out text. This code is working with a sample file. But it is not working with the scanned pdf file. The pdf to doc conversion is taking place, but the strike-through detection does not.
