GroupDocs.Signature provides TextSearchOptions class to specify different options to search for Text electronic signatures within document.

Here are the steps to search for Text e-signatures using GroupDocs.Signature API:

  • Create new instance of Signature class and pass source document path as a constructor parameter;
  • Instantiate the TextSearchOptions object according to your requirements and specify additional search options (if needed);
  • Call search method of Signature  class instance and pass TextSearchOptions to it.

This example shows how to search for Text e-signature in the document.

Signature signature = new Signature(sample.pdf);
// setup search options
TextSearchOptions options = new TextSearchOptions();
// specify as true to search all pages of a document
// search only page with specified number
// specify text math type    
// specify text to search
options.setText("John Smith");
// search for text signatures in document
List<TextSignature> signatures =,options);
// output signatures
for (TextSignature textSignature : signatures)
     if (textSignature != null)
         System.out.print("Found Text signature at page "+sign.getPageNumber()+" with type ["+sign.getSignatureImplementation()+"] and text '"+sign.getText()+"'.");
         System.out.print("Location at "+sign.getLeft()+"-"+sign.getTop()+". Size is "+sign.getWidth()+"x"+sign.getHeight()+".");
