Accessors

maxScale

get maxScale(): number
The maximum scale the user is allowed to zoom to within the view. Setting this value to 0 allows the user to over-zoom layer tiles.

Returns number
set maxScale(value): void
Parameters
- value: number
Returns void

minScale

get minScale(): number
The minimum scale the user is allowed to zoom to within the view.

Returns number
set minScale(value): void
Parameters
- value: number
Returns void

parent

get parent(): this
The parent settings that these settings will inherit from.

Returns this
Inherited from Settings.parent
set parent(value): void
Parameters
- value: this
Returns void
Inherited from Settings.parent

rotationEnabled

get rotationEnabled(): boolean
Indicates whether the user can rotate the map. The default is true.

Returns boolean
set rotationEnabled(value): void
Parameters
- value: boolean
Returns void

snapToZoom

get snapToZoom(): boolean
When true, the view snaps to the next LOD when zooming in or out. When false, the zoom is continuous. The default is false.

Returns boolean
set snapToZoom(value): void
Parameters
- value: boolean
Returns void

viewSync

get viewSync(): ViewSyncConstraints
Properties on the view that get constrained when it is synchronized with another map.

Returns ViewSyncConstraints
set viewSync(value): void
Parameters
- value: ViewSyncConstraints
Returns void
