Note: To modify a text annotation, a user must a) be within the text annotation mode, and b) have the text annotation selected. A selected text annotation will have a cyan frame around it.
To change the text box size of a text annotation, the annotation must first be selected (a cyan frame will be around it). Next, use an expand gesture (drag two fingers apart from one another) to increase the size of the text annotation. To decrease the size, use a pinch gesture instead.
The placement of a text annotation can also be changed in a couple of ways. To change the annotation's position, tap and hold anywhere on the image, and then drag the annotation to the desired position. To change the annotation's orientation, rotate two fingers on the screen clockwise or counter-clockwise.
Once the desired changes to text annotation size and placement, select Save.
