- Callsearch method of Signature class instance and pass QrCodeSearchOptions to it.
This example shows how to make advanced search for QR-code signature in the document.
Signature signature = new Signature("sample.pdf");
QrCodeSearchOptions options = new QrCodeSearchOptions();
options.setAllPages(true); // this value is set by default
// single page number
options.setPageNumber(1);
// setup extended search in pages setup
PagesSetup pagesSetup = new PagesSetup() ;
pagesSetup.setFirstPage(true);
pagesSetup.setLastPage(true);
pagesSetup.setOddPages(false);
pagesSetup.setEvenPages(false);
options.setPagesSetup(pagesSetup);
// specify special barcode type to search
options.setEncodeType(QrCodeTypes.QR);
// specify text match type
options.setMatchType(TextMatchType.Exact);
// specify text pattern to search
options.setText("12345678");
// search for signatures in document
List<QrCodeSignature> signatures = signature.search(QrCodeSignature.class, options);
System.out.print("\nSource document contains following signatures.");
for (QrCodeSignature qrCodeSignature : signatures)
{
System.out.print("QRCode signature found at page "+qrCodeSignature.getPageNumber() +" with type "+qrCodeSignature.getEncodeType() +" and text "+ qrCodeSignature.getText());
}
