Search for Text e-signatures
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
options.setAllPages(true);
// search only page with specified number
options.setPageNumber(1);
// specify text math type
options.setMatchType(TextMatchType.Contains);
// specify text to search
options.setText("John Smith");
// search for text signatures in document
List<TextSignature> signatures = signature.search(TextSignature.class,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()+".");
