Sign a PDF File and Save it in DOCX Format using C# Code

using (Signature signature = new Signature("sample.pdf"))
{
    // create QRCode option with predefined QRCode text
    QRCodeSignOptions signOptions = new QRCodeSignOptions("JohnSmith")
    {
        EncodeType = QRCodeTypes.QR,
        Left = 100,
        Top = 100
    };
    PdfSaveOptions pdfSaveOptions = new PdfSaveOptions()
    {
        FileFormat = PdfSaveFileFormat.DocX,
        OverwriteExistingFiles = true
    };
    // sign document to file
    signature.Sign("SignedPdf.docx", signOptions, pdfSaveOptions);
}

Use C# to Search and Delete Signatures from a DOCX File

// initialize Signature instance
using (Signature signature = new Signature("signed.docx"))
{
    BarcodeSearchOptions options = new BarcodeSearchOptions();
    List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);
    List<BaseSignature> signaturesToDelete = new List<BaseSignature>();
    // collect signatures to delete
    foreach (BarcodeSignature temp in signatures)
    {
        if (temp.Text.Contains("John"))
        {
            signaturesToDelete.Add(temp);
        }
    }
    // delete signatures
    DeleteResult deleteResult = signature.Delete(signaturesToDelete);
    if (deleteResult.Succeeded.Count == signaturesToDelete.Count)
    {
        Console.WriteLine("All signatures were successfully deleted!");
    }
    else
    {
        Console.WriteLine($"Successfully deleted signatures : {deleteResult.Succeeded.Count}");
        Console.WriteLine($"Not deleted signatures : {deleteResult.Failed.Count}");
    }
    Console.WriteLine("List of deleted signatures:");
    foreach (BaseSignature temp in deleteResult.Succeeded)
    {
        Console.WriteLine($"Signature# Id:{temp.SignatureId}, Location: {temp.Left}x{temp.Top}. Size: {temp.Width}x{temp.Height}");
    }
}
