Multilayer Polyline symbol This is a polyline symbol with multiple layers. Each layer has its own properties, like width and dash patterns, that can be combined to create line symbols with special effects (a solid road with dashed pattern on top to show the center line, for example). These symbols are rendered with polyline geometry.
Creates a multilayer polyline symbol object with symbol layers and SymbolReferenceProperties.
Clones the MultilayerPolylineSymbol.
Creates a swatch of the symbol. This method will scale the symbol up or down in order to fit it in to the desired width and height of the swatch.
Creates a swatch of the symbol.
The consensus color of all layers in the symbol (excluding those that are color-locked). Because MultilayerSymbol may have multiple symbol layers, this property represents the value of all color and tint color properties of constituent symbol layers, excluding any StrokeSymbolLayer in a MultilayerPolygonSymbol, as those symbol layers are outlines. The property defines the color and tint color of symbols contained in VectorMarkerSymbolElement. Constituent symbol layers whose colorLocked property is true do not change color as a result of this function. To change outline colors, modify the outline symbol layer colors individually.
The width of the symbol in device-independent pixels (DIPs). When getting the width from a multilayer polyline symbol, the value reported is the largest width of all the symbol layers it contains. The symbol width is updated when its symbol layer widths change (if there is a new largest layer width). When setting a new width at the polyline symbol level, the width of the largest symbol layer is given the provided value, and all the smaller layers are sized proportionately. An individual symbol layer can be given a specific width without affecting the other layers.
