Hello,

Thanks for your reply.
Please refer to the following method to add a digital signature.

Code: Select all

String inputFile = @"test.pdf";
String outputFile = @"res.pdf";

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(inputFile);
X509Certificate2 x509 = new X509Certificate2(inputFile_Pfx, "e-iceblue");
PdfOrdinarySignatureMaker signatureMaker = new PdfOrdinarySignatureMaker(doc, x509);
PdfCustomSignatureAppearance pdfCustomSignatureAppearance = new PdfCustomSignatureAppearance();

for (int i = 0; i < doc.Pages.Count; i++)
{
    signatureMaker.MakeSignature("signName_" + (i + 1), doc.Pages[i], 100, 100, 250, 200, pdfCustomSignatureAppearance);
}

doc.SaveToFile(outputFile, FileFormat.PDF);
doc.Close();
public class PdfCustomSignatureAppearance : IPdfSignatureAppearance
{
    public void Generate(PdfCanvas g)
    {
        float x = 2;
        float y = 2;
        float fontSize = 10;
        PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arabic", fontSize), true);
        float lineHeight = fontSize;
        g.DrawString("التوقيع الرقمي: مرحبا ", font, PdfBrushes.Red, new PointF(x, y));
