Hi gang,
I'm running into something that was confusing at first, and now--an hour later--is frustrating.
I'd like to draw an outline around an object in a picture so I can remove it from the image. The object is squarish, so I made a rectangle around it, used the nodes to adjust it just right, and finished "outlining" the thing.
I tried subtracting the outline from the image, and the image from the outline, and sliding the layers of each onto each other in the layers panel. They seem to disappear, which I've seen that others have noticed, too.
I've made the outline shape empty (uncolored), and then colored it white (like all the demos show), but no luck. I can accomplish the same thing with the other shapes (ellipse, heart, etc.) but not my custom one.
What am I doing wrong?
