using System.Security.Cryptography.X509Certificates;

namespace PDFSignature {
    class Program {
        static void Main(string[] args) {

            // Create a PDF document processor.
            using (PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor()) {

                // Load a PDF document. 
                documentProcessor.LoadDocument(@"..\..\Demo.pdf");

                // Create a visual signature using certificate, image data, and specifying  page number, signature bounds and rotation angle. 
                X509Certificate2 certificate = new X509Certificate2(@"..\..\SignDemo.pfx", "dxdemo");
                byte[] imageData = File.ReadAllBytes("..\\..\\Signature.png");
                int pageNumber = 1;
                int angleInDegrees = 45; 
                double angleInRadians = angleInDegrees * (Math.PI / 180);
                PdfOrientedRectangle signatureBounds = new PdfOrientedRectangle(new PdfPoint(620, 210), 250, 90, angleInRadians);
                PdfSignature signature = new PdfSignature(certificate, imageData, pageNumber, signatureBounds);

                // Specify signing location, contact info and reason.
                signature.Location = "USA";
                signature.ContactInfo = "john.smith@example.com";
                signature.Reason = "Approved";

                // Save the signed document.
                documentProcessor.SaveDocument(@"..\..\SignedDocument.pdf", new PdfSaveOptions() { Signature = signature });
            }
        }
    }
}
