Create Submit Button

Interactive PDF forms often require users to submit their input for processing, such as sending survey results, application forms, or feedback data. A Submit Button field provides this functionality by linking the button to a web endpoint.

The FormEditor class allows adding buttons, checkboxes, radio buttons, text fields, and other form controls.

1. Load an existing PDF document.
2. Add a Submit Button field to a specific page.
3. Set the button label and target submission URL.
4. Save the updated PDF with the new button.

    """Create Submit Button in PDF document."""
    pdf_form_editor = pdf_facades.FormEditor()
    pdf_form_editor.bind_pdf(infile)

    # Add Submit Button to PDF form
    pdf_form_editor.add_submit_btn(
        "submitbtn1",
