Overlay

Purpose

This document describes the various APIs used with overlay.

Introduction

Overlay is an image which is superimposed on top of the main image with a required transparency. The main image can be a single image during image capture mode (still image/ burst/ bracket), video image frame, snapshot image, or image frames for viewfinder (direct or client-based).

The client can use it to overlay an image onto the viewfinder, snapshots, still images and video. A client can create multiple overlays, where each overlay can be in a different format. The properties of an overlay can be changed after it has been created.
