            Page page = pdfDocument.Pages.Add(DXPaperKind.A4);

            // Create a signature field and add it to the field collection.
            SignatureField signatureField = new("signature");
            signatureField.ShowDate = true;
            pdfDocument.Fields.Add(signatureField);

            // Bind the signature field to a widget and set widget colors.
            SignatureWidgetAnnotation signatureWidget = new SignatureWidgetAnnotation(signatureField, bounds: new RectangleF(20, 400, 100, 50));
            signatureWidget.OutlineColor = PdfColor.Red;
