Active Data
Overlay: The Active Data Overlay is a dynamic overlay that superimposes
image metadata over images so that it is conveniently available to you
as you are viewing images.
The overlay is dynamic because it shows active data for whatever image
is currently being viewed. Whether
you are viewing live data from a camera, playback of a previously-stored
image sequence, manipulating an image in the application workspace, or
moving between images that are open in the application workspace, as image
data changes, the heads-up display is updated accordingly.
