It depends on what technology you're using. We would need more info 🙂
I also have the above problem. Do I need to re-splice through Aseprite?
if you're using a game engine, look for 9slice

Thank you for your reply. I am being silly. I use Unity as my development engine and I didn't realize that the source Image type under Image component can be selected as Slice. My problem has been solved
