SimpleMarkerSymbol

SimpleMarkerSymbol is used for rendering 2D Point geometries with a simple shape and color in either a MapView or a SceneView. It may be filled with a solid color and have an optional outline, which is defined with a SimpleLineSymbol.

SimpleMarkerSymbols may be applied to point or polygon features in a FeatureLayer or individual graphics. Marker symbols can be used in a 3D SceneView. However, it is recommended you use PointSymbol3D instead. The image below depicts a FeatureLayer whose point features are styled with SimpleMarkerSymbols.

Example

let symbol = {
  type: "simple-marker",  // autocasts as new SimpleMarkerSymbol()
  style: "square",
  color: "blue",
  size: "8px",  // pixels
  outline: {  // autocasts as new SimpleLineSymbol()
    color: [ 255, 255, 0 ],
    width: 3  // points
  }
};

Property Details

angle Inherited Property angle Number Inherited from MarkerSymbol

The angle of the marker relative to the screen in degrees.

Known Limitations

This property is currently not supported in 3D SceneViews.

Default Value:0

color Property color Colorautocast Autocasts from Object|number []|string

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

The color property does not apply to marker symbols defined with the cross or x style. Since these styles are wholly comprised of outlines, you must modify the outline.color property to set the color of symbols with those styles.

Default Value:[255, 255, 255, 0.25] - white, semitransparent

Examples

// CSS color string
symbol.color = "dodgerblue";

// HEX string
symbol.color = "#33cc33";

// array of RGBA values
symbol.color = [51, 204, 51, 0.3];

// object with rgba properties
symbol.color = {
  r: 51,
  g: 51,
  b: 204,
  a: 0.7
};

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

outline Property outline SimpleLineSymbolautocast

The outline of the marker symbol. The color property of this object directly modifies the overall color of marker symbols defined with the cross or x style.

Known Limitations

SimpleLineSymbol style property is not honored in a simple marker symbol's outline in a 3D SceneView. Support for outline style was added in a 2D MapView at version 4.28.

Example

let sym = {
  type: "simple-marker",  // autocasts as new SimpleMarkerSymbol()
  color: "red",
  outline: {  // autocasts as new SimpleLineSymbol()
    color: [ 128, 128, 128, 0.5 ],
    width: "0.5px"
  }
};

path Property path String

The SVG path of the icon.

Known Limitations

This property works only in 2D.

size Property size Numberautocast Autocasts from String|Number

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

Default Value:12

Examples

// size in points
symbol.size = 14;

// size in pixels
symbol.size = "20px";

// size in points
symbol.size = "14pt";

style Property style String

The marker style. Possible values are in the table below.

Value	Description
circle
cross
diamond
square
triangle
x

Default Value:circle

type Property type Stringreadonly

The symbol type.

For SimpleMarkerSymbol the type is always "simple-marker".

xoffset Inherited Property xoffset Numberautocast Inherited from MarkerSymbol Autocasts from Number|String

The offset on the x-axis in points. This value may be autocast with a string expressing size in points or pixels (e.g. 12px).

Default Value:0

Examples

// xoffset in points
symbol.xoffset = 4;

// xoffset in pixels
symbol.xoffset = "2px";

// xoffset in points
symbol.xoffset = "4pt";

yoffset Inherited Property yoffset Numberautocast Inherited from MarkerSymbol Autocasts from Number|String

The offset on the y-axis in points. This value may be autocast with a string expressing size in points or pixels (e.g. 12px).

Default Value:0

Examples

// yoffset in points
symbol.yoffset = 4;

// yoffset in pixels
symbol.yoffset = "2px";

// yoffset in points
symbol.yoffset = "4pt";

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clone Method clone(){SimpleMarkerSymbol}

SimpleMarkerSymbol	A deep clone of the object that invoked this method.

Example

// Creates a deep clone of the graphic's symbol
let symLyr = graphic.symbol.clone();
