How to search for Image signatures Leave feedback

Here are the steps to search for Image signatures within the document using GroupDocs.Signature:

• Create a new instance of the Signature class and pass the source document path as a constructor parameter.
• Instantiate the ImageSearchOptions object according to your requirements and specify additional search options (if needed).
• Call the Search method of the Signature class instance and pass the ImageSearchOptions to it. The code snippet below demonstrates how to search for Image electronic signature in the document.

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

  // Search document
  const signatures = signature.search(signatureLib.ImageSignature.class, signatureLib.SignatureType.Image).toArray();
  console.log(`\nSource document ['${fileName}'] contains the following image signature(s).`);

  // Output signatures
  for (const imageSignature of signatures) {
    console.log(`Found Image signature at page ${imageSignature.getPageNumber()} and size ${imageSignature.getSize()}.`);
  }
