Quick Start (MTOM):Adding a signature field using the web service API

The following C# code example adds a signature field, named SignatureField1, to a PDF document that is based on a PDF file named Loan.pdf. The PDF document that contains the new signature field is saved as a PDF file named LoanSig.pdf. (See Adding Signature Fields.)
