Verify Barcode signatures in the document Leave feedback

GroupDocs.Signature provides the BarcodeVerifyOptions class to specify different options for verifying Barcode signatures.

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

• Create a new instance of the Signature class and pass the source document path as a constructor parameter.
• Instantiate the BarcodeVerifyOptions object according to your requirements and specify the verification options.
• Call the Verify method of the Signature class instance and pass the BarcodeVerifyOptions to it.

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

 // The path to the documents directory.
  const filePath = Constants.SAMPLE_SIGNED_MULTI; 
  // Initialize Signature instance
  const signature = new signatureLib.Signature(filePath);

  // Initialize BarcodeVerifyOptions
  const options = new signatureLib.BarcodeVerifyOptions();
  options.setAllPages(true); // This value is set by default
  options.setText('John');
  options.setMatchType(signatureLib.TextMatchType.Contains);

  // Verify document signatures
  const result = signature.verify(options);

  if (result.isValid()) {
    console.log('\nDocument was verified successfully!');
  } else {
    console.log('\nDocument failed the verification process.');
  }
