Extron Electronics Annotator User Guide - Manual (Page 42)

Whiteboard — Select this to create a white canvas for annotations. No
input video image is visible. To remove the white canvas, reselect the
Whiteboard button, select mute, or switch inputs.
Spotlight — Select this to create an ellipse to focus on a specific area of
the screen, while the outer area’s brightness is greatly reduced. The
shape and size of the ellipse is adjustable by dragging the cursor while
outside of it, to any point. The ellipse can be moved to any point by
dragging the cursor while within the ellipse.
Zoom — Select this to zoom in to a specific area of the screen. Using the
cursor, create a rectangle at the desired area and the Annotator zooms in
to view that area. If the boundaries of the area are beyond the zoom
capabilities, then the view will not change. To zoom out draw a small
rectangle (<100 pixels, ~1 inch x 1 inch) and the normal view is restored.
Pan — Selecting this while in zoom mode, allows the user to move the
focus to a new area. Place the cursor on a zoomed image and drag to
the desired area
