CalloutVisualizationMode
Display mode of callouts with the time and length of the route. Unlike DisplayFlag for each individual route object, it affects not only the display but also the calculation of the positions of the callouts. See IRouteMapObject::display_flags. See IRouteMapObject::callout_position.
Properties
Show callouts (including DisplayFlag) and calculate positions for them if at least one route is added to the source.
Show callouts (considering DisplayFlag) and calculate positions for them only if more than one route object is added to the source.
Do not show callouts and do not calculate positions for them.
