Table 1. Special Coordinate Space Names
Symbol Description
@ Root space.
# Pixel space.
* Display pixel space. You can use this special name only when specifying the space name for graphics.
^ Alias for the root space.
. Current SelectedSpaceName for an image. You can use this special name only with methods implemented by the CogImage object; there is no "selected space" for a CogCoordinateSpaceTree.
.. Parent space name of the current selected space.
$ The child coordinate space created by a parent space for its children. The VisionPro graphics system uses "$" to allow multigenerational hierarchies of shapes. You can obtain this space using a graphic's GetParentFromChildTransform method.
