Python: AttributeError: 'PageObject' object has no attribute 'extract_images'

[Melcu54]

hello, I try to convert with OCR some pdf that contains images. I got this error:

Traceback (most recent call last):
  File "E:\Carte\BB\17 - Site Leadership\alte\Ionel Balauta\Aryeht\Task 1 - Traduce tot site-ul\Doar Google Web\Andreea\Meditatii\2023\OCR.py", line 31, in <module>
    image = page.extract_images()[0]["obj"]
AttributeError: 'PageObject' object has no attribute 'extract_images'

this is the code:

import os
import PyPDF2
import pytesseract
from PIL import Image
from pdf2image import convert_from_path

# Path to the folder containing PDF files
input_folder = "d:/doc/doc"

# Path to the folder where text files will be saved
output_folder = "d:/doc/doc"

# Path to the Tesseract OCR executable (change if necessary)
pytesseract.pytesseract.tesseract_cmd = r"C:\Program Files\Tesseract-OCR\tesseract.exe"

# Get a list of all PDF files in the input folder
files = [f for f in os.listdir(input_folder) if f.endswith(".pdf")]

# Loop through each PDF file and convert it to text using OCR
for file in files:
    pdf_path = os.path.join(input_folder, file)
    txt_path = os.path.join(output_folder, os.path.splitext(file)[0] + ".txt")

    # Extract images from PDF and perform OCR on each image
    images = []
    with open(pdf_path, "rb") as file:
        pdf_reader = PyPDF2.PdfFileReader(file)

        for page_num in range(pdf_reader.numPages):
            page = pdf_reader.getPage(page_num)
            image = page.extract_images()[0]["obj"]
            images.append(Image.frombytes("RGB", image.size, image.data))

    # Perform OCR on images and extract text
    text = ""
    for image in images:
        text += pytesseract.image_to_string(image)

    # Save the extracted text to a text file
    with open(txt_path, "w", encoding="utf-8") as txt_file:
        txt_file.write(text)

print("Conversion complete!")

can someone fix my code so it works?

When you have problems, read the documentation.

https://pypdf2.readthedocs.io/en/latest/...bject.html

PageObject does not have an extract_images() method. It has a images property that will return a list of images for the page. This was a change made in September 2022. If you are using pypdf2 2.12.0 or newer, use the images property instead of the extract_images() method.
