TextSearchOptions options = new TextSearchOptions();
options.setAllPages(false);
options.setPageNumber(1);
options.setMatchType(TextMatchType.Exact);
options.setText("John Smith");
// search for text signatures in document
List<TextSignature> signatures = signature.search(TextSignature.class,options);
System.out.print("\nSource document contains following text signature(s).");
// enumerate all signature for output
//foreach to while statements conversion
try
{
for (TextSignature sign : signatures)
{
if (sign != 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()+".");
