// Create PDF file security
String ownerPassword = "owner password";
String userPassword = "user password";
int denyPrinting = PdfFilePermissions.ALL ^ PdfFilePermissions.PRINTING;
PdfFileSecurity pdfFileSecurity = new PdfFileSecurity(ownerPassword, userPassword, denyPrinting);

// Create options
PdfFileOptions pdfFileOptions = new PdfFileOptions();
pdfFileOptions.setPdfFileSecurity(pdfFileSecurity);
