Export to FDF

Contents
[ ]

FDF is a lightweight format designed specifically for storing and transferring PDF form data without embedding the entire document. In this example, a Form object is initialized from the aspose.pdf.facades module, allowing developers to interact with AcroForm fields and export their values.

  1. Create an instance of pdf_facades.Form() to work with PDF form fields.
  2. Call ‘bind_pdf()’ to attach the PDF document containing the form.
  3. Use ‘open(’)’ to create a writable binary stream for the FDF file.
  4. Export Form Data. Call ’export_fdf()’ to extract and save all form field values.
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


# Export Data to FDF
def export_form_data_to_fdf(infile, outfile):
    """Export PDF form data to FDF file."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Create FDF file stream
    with open(outfile, "wb") as fdf_output_stream:
        # Export form data to FDF file
        pdf_form.export_fdf(fdf_output_stream)
