ROI Color Properties
All ROIs have the color properties of True Color, False Color, Use True Color, and Visible.
List ROIs have these color properties in addition: State List, False State Visible, True State Visible, and
Color By States.
The Color by States property updates automatically based on how you are using the ROI. If you change the
Use True Color property to True, all of the ROIs in the list will take on the True Color and the Color by
States property are set to False
If you change the Use True Color property to False, all of the ROIs in the list will take on the False Color
and the Color by States property will again be set to False.
If you link a boolean list (from a data link in the Impact Connector control) to the State List property, the
ROIs in the list will take on True Colors and False Colors corresponding to the True and False values in the
State List, and the Color by States property is set to True.
Also, when the value of the State List is updated, the ROIs in the List become visible or invisible, based on
the settings of the True State Visible and False State Visible properties. If the Visible property is changed,
both the True State Visible and the False State Visible properties are changed to match it.
