Get the scale and location onchange and save it

[markarupert]

I am creating an app where the user can drag small images onto a picture and position them. They can also stretch or shrink the images to create the layout that they want.

I want to be able to save the changes an reload them to the location and size the user set them at.

I cannot figure out how to get the size and location to save it. And then how to I save it back after recreating the images later.
