# Composing Transformations

The coordinate space tree includes methods that let you obtain a composed transformation that can map points between any two spaces anywhere in the coordinate space tree.

If you request a transformation using the GetTransform method of an image, you specify the names of the coordinate spaces between which you want to transform points. You can specify the name of a user space, you can specify "." for the currently SelectedSpaceName, you can specify "@" for the root space, or you can specify "#" for pixel space.
