Verifying Text signatures in advance Leave feedback
GroupDocs.Signature provides TextVerifyOptions class to specify different options for verification of Text signatures.
Here are the steps to verify Text signature within the document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter.
- Instantiate the TextVerifyOptions object according to your requirements and specify verification options
- Call Verify method of Signature class instance and pass TextVerifyOptions to it.
- Analyze VerificationResult result if needed.
This example shows how to verify Text signature in the document. See VerificationResult
using (Signature signature = new Signature("signedSample.pdf"))
{
TextVerifyOptions options = new TextVerifyOptions()
{
// specify if all pages shoudl 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
SignatureImplementation = TextSignatureImplementation.Stamp,
// specify if form fielsd should be verified
FormTextFieldTitle = "Sample",
FormTextFieldType = FormTextFieldType.RichText
};
// verify document signatures
VerificationResult result = signature.Verify(options);
if (result.IsValid)
{
Console.WriteLine("\nDocument was verified successfully!");
}
else
{
Console.WriteLine("\nDocument failed verification process.");
}
}
