/* Overview */
A layer can be envisioned as a transparent film that is overlaid on the target and contains the actual HotSpots. Technically their can be as many layers as desired, overlaying each others.
A layer covers the whole physical area of its target, i.e. the dimensions of the page of a document.
===HotSpot===
===Annotation===
An Annotation is a collection of Ink strokes that sits on a layer and typically represents redlining or additional information to a document, like a diagram or a photo.
