I'm relatively new to python, and I'm trying to replace an image at a given location. The idea is to check if the extracted image in the PDF matches the image I want to replace. If it does, I extract the location and put the new image in its place. I'm done with the extracting and checking part. Could someone please help me with the later part?

Step 1: convert mypdf.pdf to full_page_image.jpg
from pdf2image import convert_from_path
pages = convert_from_path('mypdf.pdf', 500)
pages[x].save('full_page_image.jpg', 'JPEG') #where x is your page number minus one
Step 2: overlay image_to_be_added onto full_page_image
import cv2
import numpy as np
full_page_image = cv2.imread('full_page_image.jpg')
image_to_be_added = cv2.imread('image_to_be_added.jpg')
final_image = full_page_image.copy()
final_image[100:400,100:400,:] = image_to_be_added[100:400,100:400,:] #adjust the numbers according to the dimensions of the image_to_be_added
cv2.imwrite(final_image.jpg, final_image)
Step3: convert final_image.jpg to final_pdf.pdf
from PIL import Image
final_image2 = Image.open(r'final_image.jpg')
final_image3 = final_image2.convert('RGB')
final_image3.save(r'final_pdf.pdf')
