Is there a way to automatically stroke in the MIDDLE of a selection?
I can't exactly figure out how to describe it. Essentially, is there a way to stroke, like you can on the inside, outside, or center of selection boundries, but have the stroke center itseslf in the middle of a selection?
Currently, the only way i can *sort of* do this is with a backwards method of taking a shape and inverting its color, then doing an inside stroke layer effect with the color of the original, like this

(To repeat, the actual shape here is white, the inside stroke is why it looks purple with a white center line)
This is annoying because:
- it pretty much only works with uniform width lines, instead of, say, a shape whos border changes width as it goes around.
- it isnt actually a stroke, its a layer effect, therefore i cant alter it without altering the main whatever it is im working on.
3. where as a regular stroke (like from the edit dropdown menu) can be pencil tool/bianary, this is always a brush (i know theres some nonsense to make it a pixel outline, but it doesnt actually get me any closer to my task)
The way i do it now besides this, is to take whatever selection and just narrow it by however much until its as close as possible, and then manually go through the entire outline and tune it up by hand. Which i can, do, technicly, but this seems like the kind of thing that A: should be in ps already and B: if it isnt could be like, a plugin or something.
To be clear, essentially what im after is a pen path that can do its own stroke. The reason i dont use pens is because many times there are pre existing, complex shapes that would be time consuming to do by hand especially when i need this stroke for a guide, not for the final product, making it feel like a waste of time. That is, i know the pen tool exists and its a viable alternative but it would still take just as long to do as any other dumb method ive been using.
im not putting this in as an idea because im so sure its possible and im just missing it, but if it isnt i guess ill submit it as one? thank you all 🙂
