How to draw a circle around something in Preview.app
Just what the thread title says. Specifically, I want to draw a circle around something to highlight that thing in the image, so I can send the image to another user and the circle will draw their attention to the item that is circled.
Thus, I do *NOT* want to fill in the circle with a solid color, because that will obscure the part of the image I am trying to draw attention to.
It seems that generally speaking there are no words annotating the interface items in the Preview app, so I don't think there is a way for the user to know what any of the functions are or how to use them.
Thanks in advance!
