Not exactly. sf::Transform is essentially a 4x4 transformation matrix. So all the applied operations are calculated into the matrix and thus you can't extract the original inputs.
What you can do with a transformation matrix is decompose it into it's combined components (translation, rotation and scale), see also this StackExchange answer.

As for the StackOverflow question, I'll answer there directly.

Thanks man, it helped me alot. I was very confused with the coordinate system and this transformation matrix because I am new.
