“·” 图像的当前空间,即CogImage中的“SelectedSpaceName”表示的名字空间
“#” 像素空间,即坐标原点为图片左上角的坐标空间,该坐标空间的坐标值仅为整数。
“@” 根空间,默认的坐标空间都是基于根空间。该空间坐标原点为图片左上角,该坐标空间的坐标值类型为浮点型。
“*” 控件的像素空间,主要是显示控件上面使用。

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.
