EPS vs Other Formats

Python - Generate EPS

Using QR Code + Pillow

import qrcode
import subprocess
from PIL import Image

def generate_eps_qr(data, filename):
    """Generate QR code and convert to EPS."""
    
    # Generate QR as PNG first
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_H,
        box_size=10,
        border=2,
    )
    qr.add_data(data)
    qr.make(fit=True)
    
    img = qr.make_image(fill_color='black', back_color='white')
    temp_png = 'temp_qr.png'
    img.save(temp_png)
    
    # Convert PNG to EPS using ImageMagick
    subprocess.run(['convert', temp_png, filename])
    print(f'EPS QR generated: {filename}')

generate_eps_qr('https://example.com', 'qrcode.eps')

Using reportlab for Vector

from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
import qrcode
from io import BytesIO

def create_eps_vector_qr(data, output_file):
    """Create vector QR code for professional use."""
    import subprocess
    
    # Generate high quality PNG
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_H,
        box_size=50,  # Large box size
        border=2,
    )
    qr.add_data(data)
    qr.make(fit=True)
    
    img = qr.make_image(fill_color='black', back_color='white')
    img.save('temp_qr.png')
    
    # Potrace: Convert raster to vector
    subprocess.run(['potrace', 'temp_qr.png', '-e', output_file])
    print(f'Vector EPS created: {output_file}')

create_eps_vector_qr('https://example.com', 'qrcode.eps')

Adobe Integration

Using in Adobe Illustrator

1. File → Open → Select EPS QR code
2. QR code appears as editable vector
3. Resize infinitely without quality loss
4. Change color if needed (black modules only)
5. Export as PDF for final print

Using in InDesign
