Ready to Code? Let’s Get Started!

Now, let’s dive into some actual code! Here’s how to extract images and text from a PDF using PyMuPDF:

Image Extraction-

import fitz
import io
import base64
from PIL import Image

def extract_images_from_pdf(pdf_path):
images = []
try:
pdf_document = fitz.open(pdf_path)
for page_num in range(len(pdf_document)):
page = pdf_document.load_page(page_num)
image_list = page.get_images(full=True)
for img_info in image_list:
xref = img_info[0]
base_image = pdf_document.extract_image(xref)
image_bytes = base_image[“image”]
img_pil = Image.open(io.BytesIO(image_bytes))
img_pil = img_pil.convert(‘RGB’)
img_byte_arr = io.BytesIO()
img_pil.save(img_byte_arr, format=’JPEG’)
img_base64 = base64.b64encode(img_byte_arr.getvalue()).decode(‘utf-8’)
images.append({‘page_number’: page_num, ‘image_data’: img_base64})
pdf_document.close()
except Exception as e:
print(f”Error: {str(e)}”)
return images

pdf_path = ‘path/to/your/pdf/document.pdf’
extracted_images = extract_images_from_pdf(pdf_path)
for image in extracted_images:
print(f”Page {image[‘page_number’]}: {image[‘image_data’][:50]}…”)

Text Extraction

import fitz

def extract_text_from_pdf(pdf_path):
text = “”
try:
pdf_document = fitz.open(pdf_path)
for page_num in range(len(pdf_document)):
page = pdf_document.load_page(page_num)
text += page.get_text()
pdf_document.close()
except Exception as e:
print(f”Error: {str(e)}”)

pdf_path = ‘path/to/your/pdf/document.pdf’
extracted_text = extract_text_from_pdf(pdf_path)
print(extracted_text)
