GroupDocs.Signature provides different properties in QrCodeVerifyOptions class to specify verification of QR Code signatures.

Here are the steps to verify QR Code signature within the document with GroupDocs.Signature:

Create new instance of Signature class and pass source document path as a constructor parameter. *Instantiate the QrCodeVerifyOptions object according to your requirements and specify verification options
Call Verify method of Signature class instance and pass QrCodeVerifyOptions to it.
Analyze VerificationResult result if needed.

This example shows how to verify QR Code signature in the document. See VerificationResult

using (Signature signature = new Signature("sample.pdf"))
{
    QrCodeVerifyOptions options = new QrCodeVerifyOptions()
    {
        // specify if all pages should be verified
        AllPages = false,
        PagesSetup = new PagesSetup() {  FirstPage = false, LastPage = true, OddPages = false, EvenPages = true },
        // specify text pattern
        Text = "John",
        // specify verification text pattern
        MatchType = TextMatchType.Contains,
        // specify types of QR code to verify
        EncodeType = QrCodeTypes.QR
    };
    // verify document signatures
    VerificationResult result = signature.Verify(options);
    if (result.IsValid)
    {
        Console.WriteLine("\nDocument was verified successfully!");
    }
    else
    {
        Console.WriteLine("\nDocument failed verification process.");
    }
}
