How to Protect Annotations with Foxit PDF SDK for Web

Protecting annotations adds another layer of security for your PDF documents. Our feature described below sets the annotation to a locked state where only the reply can not be edited.

With Foxit PDF SDK for Web, this is easily achieved with the following code:

pdfDoc.getAnnots().then((data) => { 
 let annot = data[0][0]; 
 annot.setFlags(128); 
});
