Fill Check Box Fields

The check box is commonly used in PDF forms to represent binary choices such as subscriptions or agreement confirmations. In this example, the Form facade from aspose.pdf.facades is used to access form fields and set their values to a selected state. After updating the check boxes, the filled PDF is saved as a new document.

1. Initialize ‘pdf_facades.Form()’ to manage form field interactions.
2. Use ‘bind_pdf()’ to attach the source PDF containing check box fields.
3. Call ‘fill_field()’ to mark fields like ‘subscribe_newsletter’ and ‘accept_terms’ as selected.
4. Save the updated Document.

    # Fill check box fields by name
    pdf_form.fill_field("subscribe_newsletter", "Yes")
    pdf_form.fill_field("accept_terms", "Yes")

    # Save updated PDF
    pdf_form.save(outfile)
