To do this, press the Calibration button. This will place a calibration line in the center of the image.
Place the calibration line over item you are using for calibration, with the points place on the edges of the object. The calibration will start out being measured in pixels, so when you are satisfied with the placement of the Calibration line, long press or right click on the annotation to open the Edit Calibration Form will show.
Enter the length of the calibration object and press the Save button and the form will close. Pressing the Cancel button will dismiss the form and not save the edits.

To perform a Cobb angle measurement, press the Cobb Angle button. This will place the Cobb angle measurement in the center of the image. You can move each of the points by dragging them.

The Cobb angle was first described in 1948 by American orthopedic surgeon John R Cobb (1903-1967).
Create a copy
This will create a copy of the current image and its annotations and add it below the shot in the shot list, then remove the annotations from the original image.
