Measuring Length of a Perpendicular Line
You can measure length of a perpendicular line drawn from a point to a reference line drawn between two points on an
image.
1 Display the toolbar.
2 Press the [COLOR] button to select color of
measurement results.
3 Press the [PERPENDICULAR MEASUREMENT] button.
A blue frame appears around the button.
4 Specify two arbitrary points (A and B on the figure) to
draw a reference line for measurement.
5 Specify an arbitrary point (C in the figure) from which
you want to measure distance to the reference line.
If you specify the point, a perpendicular line is drawn from
the point to the reference line and its distance is shown.
6 Repeat step 5 to continue measuring another
perpendicular line from the same reference line.
7 To display or hide the measured result, switch to
display or hide overlay.
You cannot selectively display or hide only the measured
result. Switch to display or hide the entire overlay.
8 To end measurement, press the [PERPENDICULAR
MEASUREMENT] button to deselect the tool.
