Detailed Description

This is a polygon symbol with multiple layers. Each layer has its own properties like width, height, and offset, that can be combined to create polygon symbols with special effects (a polygon with a marker in the center, for example). These symbols are rendered with polygon geometry.

Note: Symbol layers in a multilayer symbol are in reverse order of how they appear in the JSON representation.

// in this multilayer symbol pseudocode json, the 'symbolLayers' ordered list of symbol
// layers contains a solid stroke symbol layer followed by a solid fill symbol layer.
{ "symbolLayers": [{"type": "CIMSolidStroke", "color": "black"},{"type": "CIMSolidFill", "color": "red"}],"type": "CIMPolygonSymbol" }

// this is the solid fill symbol layer, the reverse order from the json representation
auto* symbolLayerIndexZero = multilayerSymbol->symboLayers()->at(0); // red fill in the image below

// this is the solid stroke symbol layer, the reverse order from the json representation
auto* symbolLayerIndexOne = multilayerSymbol->symboLayers()->at(1); // black outline in the image below

"MultilayerPolygon symbol"

Multilayer symbol consisting of two layers.
