Provides access to further properties of a data driven symbol commonly used with a dot density renderer.
| Description | ||
|---|---|---|
|  | BackgroundColor | The background color. | 
|  | Color | Fill color. | 
|  | DotCount | The number of dots used to fill. | 
|  | DotSize | The size of dots used to fill. | 
|  | DotSpacing | The distance between dot centers, expressed as a percentage of dot size. | 
|  | FixedPlacement | Indicates if the dots are always placed at the same location (the alternative is random placement). | 
|  | Outline | Line symbol of fill outline. | 
|  | RandomSeed | Defines how the random generator is initialized to draw dots randomly. | 
| Interfaces | Description |
