import asposebarcode as barcode

# 1. Initialize the generator for QR code
generator = barcode.BarcodeGenerator(
    symbology=barcode.Symbology.QR,
    code_text="1234567890"  # Sample data required by Royal Mail
)

# 2. Configure Royal Mail specific parameters
generator.parameters.qr.error_correction = barcode.QRErrorCorrectionLevel.Q
generator.parameters.qr.version = 5               # Recommended version for Royal Mail
generator.parameters.qr.module_size = 5           # Size of each module (pixel)
generator.parameters.qr.quiet_zone = 4            # Quiet zone width

# 3. Save the QR code as PNG (lossless for best readability)
output_path = "output/royal_mail_qr.png"
generator.save(output_path, barcode.BarcodeImageFormat.PNG)

# 4. Initialize the reader and decode the saved image
reader = barcode.BarcodeReader()
reader.read(output_path)

# 5. Extract and display the decoded text
if reader.found:
    decoded_text = reader.get_code_text()
    print(f"Decoded text: {decoded_text}")
else:
    print("No QR code detected.")
