Fill Barcode Fields

Barcode fields in PDF forms allow encoded information to be stored and displayed visually as barcodes. In this example, the Form facade from the aspose.pdf.facades module is used to access form fields and assign a barcode value. Once the data is filled, the PDF is saved with the updated barcode content.

1. Initialize ‘pdf_facades.Form()’ to manage PDF form interactions.
2. Call ‘bind_pdf()’ to attach the PDF containing barcode fields.
3. Use ‘fill_field()’ to assign a barcode value.
4. Save the updated Document.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Fill Barcode Fields
def fill_barcode_fields(infile, outfile):
    """Fill barcode fields in PDF form."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Fill barcode fields by name
    pdf_form.fill_field("product_barcode", "123456789012")

    # Save updated PDF
    pdf_form.save(outfile)
