LineSymbol3DLayer

require(["esri/symbols/LineSymbol3DLayer"], function(LineSymbol3DLayer) { /* code goes here */ });
Class: esri/symbols/LineSymbol3DLayer
Inheritance: LineSymbol3DLayer Symbol3DLayer Accessor
Since: ArcGIS API for JavaScript 4.0

LineSymbol3DLayer renders Polyline geometries using a flat 2D line with a LineSymbol3D in a 3D SceneView. MapView does not support 3D symbols.

The color of the line is set in the material property. The width of the line may be defined in either points or pixels with the size property. Line width and color can also be data-driven by adding size and/or color visual variables to any Renderer that uses this symbol layer.

A LineSymbol3DLayer must be added to the symbolLayers property of a LineSymbol3D. It may also be added to PolygonSymbol3D symbols to create outlines of polygon features. Multiple symbol layers may be used in a single symbol. The image below depicts a line FeatureLayer whose features are symbolized with a LineSymbol3D containing a LineSymbol3DLayer.

See Symbol3DLayer and Symbol3D to read more general information about 3D symbols, symbol layers and how they relate to one another.

Autocasting support

As of version 4.5 of the ArcGIS API for JavaScript, autocasting is universally supported for all renderers, symbols, and symbol layers in the API. So there is no need to include this module in the require() and define() module loaders of your application unless you intend to use the static method(s) of this module.

See also:
Example:
var symbol = {
  type: "line-3d",  // autocasts as new LineSymbol3D()
  symbolLayers: [{
    type: "line",  // autocasts as new LineSymbol3DLayer()
    size: 2,  // points
    material: { color: "black" }
  })]
});

Property Details

declaredClassStringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

materialObject

The material used to shade the line. This property defines the line's color.

Property:
color Color
optional

The color of the line. This can be autocast with a named string, hex string, array of rgb or rgba values, an object with r, g, b, and a properties, or a Color object.

Default value: white

Examples:
// CSS color string
symbolLayer.material = {
  color: "dodgerblue"
};
// HEX string
symbolLayer.material = {
  color: "#33cc33";
}
// array of RGBA values
symbolLayer.material = {
  color: [51, 204, 51, 0.3];
}
// object with rgba properties
symbolLayer.material = {
  color: {
    r: 51,
    g: 51,
    b: 204,
    a: 0.7
  }
};

The width of the line in points. This value may be autocast with a string expressing size in points or pixels (e.g. 12px).

Default Value: 0.75
Examples:
// width in points
symbolLayer.size = 4;
// width in pixels
symbolLayer.size = "2px";
// width in points
symbolLayer.size = "4pt";

typeString

For LineSymbol3DLayer the type is always line.

Method Details

Creates a deep clone of the symbol layer.

Returns:
TypeDescription
LineSymbol3DLayerA deep clone of the object that invoked this method.
Example:
// Creates a deep clone of the graphic's first symbol layer
var symLyr = graphic.symbol.symbolLayers.getItemAt(0).clone();

fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter:
json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns:
TypeDescription
*Returns a new instance of this class.

toJSON(){Object}inherited
