Overlay
Annotations and measurement drawings are written into “overlay”.
(1) Overview of overlay
You can think of an overlay as a transparent sheet covered on a shot image.
Annotations (text, straight line, pen and marker) and measurement results are rendered on an overlay. You can hide an
overlay to temporarily hide the rendered results or show the overlay to make all the results appear at once.
•
By using an overlay, you can add an annotation and perform measurement without modifying an original image.
•
Drawing rendered in an overlay can be saved with an image when captured or printed using the direct printing feature.
Content of overlay
•
Out of functions operated from the [TOOL MENU], execution results of the annotation function (text, straight line,
pen, and marker) are drawn on an overlay. Scales (XY measurement, X scale, scale, cross hairs, and grid line)
are not drawn on an overlay. The display of each item can be independently switched to ON and OFF.
•
All results of measurement are rendered in an overlay.
