Delete QR-code signatures from documents Leave feedback

GroupDocs.Signature provides QrCodeSignature class to manipulate QR-code signatures and delete them from the documents over Delete method.
Please be aware that Delete method modifies the same document that was passed to constructor of Signature class.

Here are the steps to delete QR-code signature from the document with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path as a constructor parameter;
• Instantiate QrCodeSearchOptions object with desired properties;
• Call Search method to obtain list of QrCodeSignature;
• Select from list QrCodeSignature object(s) that should be removed from the document;
• Call Signature object Delete method and pass one or several signatures to it.

This example shows how to delete QR-code signature that was found using Search method.

using (Signature signature = new Signature("signed.docx"))
{
    QrCodeSearchOptions options = new QrCodeSearchOptions();
    // search for QRCode signatures in document
    List<QrCodeSignature> signatures = signature.Search<QrCodeSignature>(options);
    if (signatures.Count > 0)
    {
        QrCodeSignature qrCodeSignature = signatures[0];
        bool result = signature.Delete(qrCodeSignature);
        if (result)
        {
            Console.WriteLine($"Signature with QR-Code '{qrCodeSignature.Text}' was deleted.");
        }
        else
        {
            Console.WriteLine($"Signature was not deleted from the document!");
        }
    }
}
