Annotation: add/erase

Before you begin

Consider this information when you use the Annotation tools.
Annotation allows you to comment for labeling purposes or draw attention to a specific area of interest. Multiple areas of annotation can be added to an image and then later deleted. There are two annotation methods.
  • Annotation without an arrow
  • Annotation with an arrow that includes an on-screen arrow to identify specific structures, as well as to make text entries
