ContourGroup Class

Defines a group of objects to which to apply Contour lines in a particular style. The ContourDisplay settings can contain multiple groups. Each group is described by a set of SubCategory's; all geometry belonging to any of those subcategories belongs to the group. An empty set of subcategories indicates that this is a default group, implicitly containing all subcategories that are not explicitly included in another group. Each group has an optional, non-user-facing name that applications can use to assign semantics to particular groups.

Methods

Name Description
clone(changedProps?: Partial<ContourGroupProperties>): ContourGroup Create a copy of this ContourGroup, identical except for any properties specified by changedProps.

subCategoriesEqual(other: ContourGroup): boolean Returns true if this and other contain the exact same set of subcategories.  
toJSON(): ContourGroupProps    
create(props?: Partial<ContourGroupProperties>): ContourGroup Static Create a new ContourGroup.  
fromJSON(props?: ContourGroupProps): ContourGroup Static
