Sorry, yes, I know what it is. I'm using ChatGPT to translate it into English, and I think I interpret it like this.

What I want to share is my Python script that takes 2 points from the image grid forming the tileset you want to create. It grabs only the necessary walls from the tiles on the top level and pastes them so you can draw on that image. It also saves a JSON with the information about where that image should go, so it cuts them again and saves them in the corresponding folder. If the folder doesn't exist, it creates one. So, you can go on drawing your map part by part, even using as a reference the parts you've already drawn because it considers whether a tile already exists before grabbing a parent tile.
