Detailed Description
Note: You cannot declare or create a component of this type in QML code.
Symbols describe how graphics and features look on the map. Different symbols are used with different geometry types. Marker symbols are used for point and multipoint geometries, fill symbols are used for polygon geometries, and line symbols are used for polyline geometries.

Property Documentation
JSON that can be used to instantiate the type instance.
Sizes of symbols in JSON are represented in points (not pixels). Symbol layers in a multilayer symbol are in reverse order of how they appear in the JSON representation.
Note: For Symbols of type MarkerSymbol, an angle set from JSON will be inverted (e.g. an angle of 20 will become -20).
Returns the image URL to the symbol's swatch image (read-only).
Accessing this property will force the swatch image to be created.
swatchOptions : SwatchOptions |
Returns the configuration options for the swatch image (read-only).
If these options are a changed a new swatchImage will be generated.
