How can I add a new AcroForm field to a PDF?

I have used iText to fill data into existing AcroForm fields in a PDF. I am now looking for a solution to add new AcroForm fields to a PDF. Is this possible with iText? If so, how can I do this?

This is documented in the official documentation, more specifically in the SubmitForm example. Additionally, I've written a simple example called AddField. It adds a button field at a specific position defined by new Rectangle(36, 700, 36, 30). Here is the code adapted for iText 7:

public void manipulatePdf(String src, String dest) throws IOException {
    PdfDocument pdfDoc = new PdfDocument(new PdfReader(src), new PdfWriter(dest));
    PdfAcroForm form = PdfAcroForm.getAcroForm(pdfDoc, true);

    PdfButtonFormField button = PdfFormField.createPushButton(pdfDoc, new Rectangle(36, 700, 36, 30), "post", "POST");
    button.setBackgroundColor(Color.GRAY);
    button.setValue("POST");
    button.setAction(PdfAction.createSubmitForm("http://itextpdf.com:8180/book/request", null,
            PdfAction.SUBMIT_HTML_FORMAT | PdfAction.SUBMIT_COORDINATES));
    button.setVisibility(PdfFormField.VISIBLE_BUT_DOES_NOT_PRINT);

    form.addField(button);

    pdfDoc.close();
}

As you can see, you need to create a PdfButtonFormField object and then use a PdfAcroForm instance to add the field.
