GroupDocs.Signature provides FormFieldSearchOptions class to specify different options to search for Form Field Signatures.

Here are the steps to search for Form Field signatures within the document with GroupDocs.Signature:

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

This example shows how to make advanced search for Form Field signatures in the document.

Signature signature = new Signature("signed.pdf");
FormFieldSearchOptions options = new FormFieldSearchOptions();
options.setValue("Value1");
options.setAllPages(true);
options.setName("TestField");
options.setType(FormFieldType.Text);
 
// search for signatures in document
List<FormFieldSignature> signatures = signature.search(FormFieldSignature.class, options);
System.out.print("\nSource document contains following signatures.");
for (FormFieldSignature formFieldSignature : signatures)
{
    System.out.print("FormField signature found. Name : "+formFieldSignature.getName()+". Value: " +formFieldSignature.getValue());
