GroupDocs.Signature provides BarcodeVerifyOptions class to specify different options for verification of Barcode signatures.

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

• Create new instance of Signature class and pass source document path as a constructor parameter.

• Instantiate the BarcodeVerifyOptions object according to your requirements and specify verification options

• Call verify method of Signature class instance and pass BarcodeVerifyOptions to it.

This example shows how to verify Barcode signature in the document.

Signature signature = new Signature("sample.pdf");
BarcodeVerifyOptions options = new BarcodeVerifyOptions();
options.setAllPages(true); // this value is set by default
options.setText("John");
options.setMatchType(TextMatchType.Contains);

// verify document signature
VerificationResult result = signature.verify(options);
if (result.isValid())
{
    System.out.print("\nDocument was verified successfully!");
}
else
{
    System.out.print("\nDocument failed verification process.");
}
