Returns the x and y coordinates of the center point as a list of 2 values separated by a return character, for example:
“42
345”
Originated in
Troi Dialog Plug-in 12.0

Considerations
The input rectangle can be given formatted in 2 ways:
As a list parameter “left¶top¶width¶height”, for example:
“42
345
1560
720”
Alternatively you can supply four input parameters: left ; top ; width ; height.
Example
Set Variable [ $Rectangle ; "0¶0¶2560¶1440" ]
Set Variable [ $CenterPoint ; Dial_CenterPointOfRect( "-Unused" ; $Rectangle ) ]This will return the center point, in this case “1280¶720”.
You can also supply four input parameters, left ; top ; width ; height, like this:
Set Variable [ $CenterPoint ; Dial_CenterPointOfRect( "-Unused" ; 0 ; 0 ; 2560 ; 1440) ]This will also return the center point: “1280¶720”.
