I have a custom view object in which I am drawing some objects. These
objects can overlap each other and each can have one or more tracking
rectangles within their own bounds. In certain scenarios, one object
may overlap part of a tracking rectangle from another object. (I have
created a picture of this scenario at
http://www.neuromight.com/images/trackingrect.png to help illustrate
this.)
As you can see, it's possible for an object on a foreground layer to
mask one or two corners of an underlying object's tracking rectangle
if not the entire tracking rectangle.
In attempting to draw the tracking rectangles, what is the best way to
do so, compensating for any objects that might mask tracking
rectangles of underlying objects?
Thanks,
Jason
