A freehand annotation can be placed anywhere on an imaged document. Once placed, you can change its color, opacity, and line thickness. You can also move it to a different location on the image; view its creator, creation date, and last modification date; mark it as protected or private; or delete it.
To add a freehand annotation to an image
Note: You can join different freehand annotations together, if you draw them within three seconds of each other. After three seconds the separate clicks become separate annotations.
