Overlay

Annotations and measurement results are drawn on a layer called an "overlay".
(1) Overview of the overlay
You can think of the overlay as a transparent sheet covered over a captured image.
Annotations (text, straight lines, arrows, free-hand lines, and markers) and measurement results are rendered on the
overlay. You can hide them temporarily or redisplay them by hiding or showing the overlay.
 The overlay allows you to add annotations and perform measurement without modifying an original image.
 You can save the items drawn on the overlay to an image by re-capturing the image.
Overlay and scales (scale bar, crossed scales, cross-hairs, grid, and bars for XY measurement)
The results of the functions executed from the [TOOL MENU: MEAS/DRAW] screen are drawn on the overlay.
However, the results of the functions executed from the [TOOL MENU: SCALE] screen are not drawn on the
overlay. You can show or hide each scale item individually.
