Visionpro essay-visionpro The meaning of space character

Namespaces are a very important concept in Visionpro. In short, it is a special coordinate system in the image.

The special meanings of some fixed characters in the namespaces are:

1) "." = This represents the current namespace using the input image. The name space represented by "Selectedspacename" in Cogimage.

2) "#" = Pixel space, which is the pixel coordinate space of the (0,0) point in the upper-left corner of the image. Note that the coordinate system is just an integer

3) "@" = root space, the default is the pixel coordinate system space at the (0,0) point in the upper-left corner. However, the coordinate system here supports floating point, or decimal. And the default namespace is based on the root space. This means that the standard space name is similar to the "@\ space name \ Space name"

4) "*" = pixel space of the control. This is relatively rare and is rarely seen in general. This is mainly in the Cogdisplay control (including Cogdisplay,cogrecorddisplay,cogrecordsdisplay, etc.), the main purpose is to move the mouse's current screen coordinates to the image coordinates.
