in iText, you can either flatten the form:
stamper.setFormFlattening(true);
with stamper being a PdfStamper instance;
or you can set the field to Read-Only:
form.setFieldProperty(field,
"setfflags", PdfFormField.FF_READ_ONLY, null);
with form being an AcroFields instance.
It's more or less the same in iTextSharp.
Note that the form is "gone" when you flatten it. You end up with a PDF
that no longer has an interactive form; you can't retrieve the content
of the field anymore. That's a major difference with changing the field
to read-only.
