PDF Image Extractor Guide

Overview

This skill allows users to extract images embedded within PDF documents and save them in formats such as JPEG, PNG, or TIFF. This is particularly useful for graphic designers and researchers who require high-quality visuals from PDF sources.

Extraction Process

The process involves reading the PDF file, identifying image objects, and exporting them as standalone image files.

Quick Start

from pypdf import PdfReader
import os

# Function to extract images from a PDF
def extract_images_from_pdf(pdf_file, output_dir):
    reader = PdfReader(pdf_file)
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)
    for i, page in enumerate(reader.pages):
        images = page.images
        for j, img in enumerate(images):
            with open(f"{output_dir}/image_{i+1}_{j+1}.png", "wb") as img_file:
                img_file.write(img.data)

# Extract images to output directory
extract_images_from_pdf("document.pdf", "extracted_images")

Handling Different Image Formats

Support for saving images in different formats can be added:

from PIL import Image

# Function to save image in different formats
def save_image(image_data, output_path, format='PNG'):
    image = Image.open(image_data)
    image.save(output_path, format)

# Usage
save_image(image_data, "output_image.jpeg", format='JPEG')
