Now, I need to get the path coordinates of each object, and I don't want to hover over every corner and manually write down each coordinate. Is there an automated way to get this path? Maybe there is some application or web service whence I can send my image and get the path in return? I have tried exporting each layer separately and then importing them into illustrator and vectorizing the shape (it
