# Get Transform in Space Tree

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

If user request a transformation using the GetTransform method of an image, what's needed only is the names of the coordinate spaces between which user want to transform points. In VisionPro, "." stands for the currently SelectedSpaceName, "@" stands for the root space, "#" stands for pixel space. For user spaces, just use their names.

Here is an example to get the transform between Home2D and root space:
