extraire des images de PDF

# STEP 1
# import libraries
import fitz
import io
from PIL import Image
  
# STEP 2
# file path you want to extract images from
file = "/content/pdf_file.pdf"
  
# open the file
pdf_file = fitz.open(file)
  
# STEP 3
# iterate over PDF pages
for page_index in range(len(pdf_file)):
    
    # get the page itself
    page = pdf_file[page_index]
    image_list = page.getImageList()
      
    # printing number of images found in this page
    if image_list:
        print(f"[+] Found a total of {len(image_list)} images in page {page_index}")
    else:
        print("[!] No images found on page", page_index)
    for image_index, img in enumerate(page.getImageList(), start=1):
        
        # get the XREF of the image
        xref = img[0]
          
        # extract the image bytes
        base_image = pdf_file.extractImage(xref)
        image_bytes = base_image["image"]
          
        # get the image extension
        image_ext = base_image["ext"]
