Import FDF Data

FDF (Forms Data Format) is a lightweight format used to store and transfer PDF form field values without including the entire document. In this example, the Form facade from aspose.pdf.facades is used to load a PDF form and import field data from an external FDF file. After the import process, the updated PDF is saved as a new file.

1. Initialize pdf_facades.Form() to work with interactive PDF form fields.
2. Call ‘bind_pdf()’ to attach the PDF form template.
3. Use ‘open()’ to read the FDF file in binary mode.
4. Call ‘import_fdf()’ to populate PDF fields with data from the FDF file.
5. Save the updated PDF.

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


# Import Data from FDF
def import_fdf_to_pdf_form(infile, datafile, outfile):
    """Import form data from FDF file into PDF form fields."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Open FDF file as stream
    with open(datafile, "rb") as fdf_input_stream:
        pdf_form.import_fdf(fdf_input_stream)

    # Save updated PDF
    pdf_form.save(outfile)
