How do I position an image point to an image point?

How do I position an image point from one sprite to an image point of another sprite?

Imagine you want sprite1 image point number 3 to go to sprite 2 image point number 4, it should go like this:

Sprite1:set position

X : Sprite2.ImagePointX(4) - (Sprite1.ImagePointX(3)-Sprite1.X)

Y : Sprite2.ImagePointY(4) - (Sprite1.ImagePointY(3)-Sprite1.Y)

Tell me if that works, as I did not tried it

You can also replace the number of the imahes points with the name of them.

Thanks!
