Image Overlay

Overview
This tool overlays an image on top of the input signal. You can tap/click the camera icon to take a snapshot of the current frame and use that as the overlay, or load a saved image from a file. This can be useful for aligning the camera position or an in-frame object with a previous reference, or for comparing composition, color, or exposure values.
This tool can use two different blend modes for the overlay: normal mix and difference.
Additional options provide control of the opacity, wipe amount and angle of the overlay.

A small thumbnail of the currently loaded reference frame is shown in the reference frame well on the options drawer.
