This object provides support for Optional Content Groups. OCGs hold a collection of graphical objects, and are known as layers. You can dynamically switch properties of layers to make them visible or invisible to provide navigation in a PDF document.

For more information, see The Layers Pane.

var ocgArray = doc.getOCGs();
for(var i=0; i<ocgArray.length){
if(ocgArray[i].name == Overlay){
ocgArray[i].state = true;
}
}
}
