f) Area calculation
This function is used to calculate the area in the region of interest. If an area in
the image is touched and enclosed, such enclosed area will be marked with a
range of 3 to 64 points. The newest point is colored with red (active point)
while the other points are colored white. These points and the active points are
automatically connected when they are touched, to make the touched points
active. The gradation range to be calculated can also be set. Such area is
identified with the red color as the active bar and the light blue bar in the color
scale. The instrument detects the critical area corresponding to the gradation
range in the enclosure for the purpose of area calculation.
