Flatten All Fields

Flattening removes interactivity from PDF forms by merging field values directly into the document layout. In this example, the Form facade from aspose.pdf.facades is used to bind the source PDF and apply the flatten_all_fields() method, which converts all fields into non-editable content.

1. Initialize pdf_facades.Form() to interact with PDF form fields.
2. Call ‘bind_pdf()’ to attach the source document.
3. Call ‘flatten_all_fields()’ to convert all interactive fields into static content.
4. Save the updated Document.

from io import FileIO

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


# Flatten all fields
def flatten_all_fields(infile, outfile):
    """Flatten all fields in a PDF document."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Flatten all fields in the PDF document
    pdf_form.flatten_all_fields()

    # Save updated PDF
    pdf_form.save(outfile)
