The three circles rights next to the three buttons of the Measure Function dialogue
box are used to select the color of the measurement tools during calibration. You
can choose a different color according to the image background by clicking the

the same objective. When a different objective is used, a new calibration must be
done for measurement.

the preview screen by clicking Line button. Use mouse click to select two points on
the screen, and the real distance will be
shown in the dialogue automatically.
Circle:
You can also measure the circumference and radius of a circle on the screen if the
measurement is properly calibrated. Use mouse click to select three points on the
screen, and the dialogue will show the circumference and radius of the circle
defined by these three points.
The lines and circles drawn on the screen for measurement will not be recorded in
