PictureMarkerSymbol | API Reference | ArcGIS Maps SDK for JavaScript 4.31

PictureMarkerSymbol renders Point graphics in either a 2D MapView or 3D SceneView using an image. A url must point to a valid image. PictureMarkerSymbols may be applied to point features in a FeatureLayer or individual graphics. The image below depicts a FeatureLayer whose point features are styled with a PictureMarkerSymbol.

Known Limitations:

SVG documents must include a definition for width and height to load properly in Firefox.
Animated GIF and PNG images are not supported in 3D SceneView.
The height and width of the symbol is restricted to no more than 200px.
Animated SVG images are currently not supported.

To avoid CORS issues with this symbol, do one of the following:

Make certain that the image is hosted on a CORS enabled server.
Use an image hosted on the same domain as the application.
Install a proxy.

Example

let symbol = {
  type: "picture-marker",  // autocasts as new PictureMarkerSymbol()
  url: "https://static.arcgis.com/images/Symbols/Shapes/BlackStarLargeB.png",

  height: "64px"
};

Property Details

angle Inherited Property angle Number Inherited from MarkerSymbol

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

Default Value:0

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.

height Property height Numberautocast Autocasts from Number|String

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

The maximum allowed height of a picture marker symbol is 200px. If you set any value higher than 200px, then the image will be scaled down to a height of 200px while preserving the aspect ratio of the image.

Default Value:12

Examples

// height in points
symbol.height = 14;

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

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

type Property type Stringreadonly

The symbol type.

For PictureMarkerSymbol the type is always "picture-marker".

url Property url String

The URL to an image or SVG document. To avoid CORS issues with this symbol, do one of the following:

Make certain that the image is hosted on a CORS enabled server.
Use an image hosted on the same domain as the application.
Install a proxy.

Known Limitations

SVG documents must include a definition for width and height to load properly in Firefox.
Animated GIF and PNG images are not supported in SceneView. See the Custom WebGL layer view sample to learn how to accomplish this using WebGL.
Animated SVG images are currently not supported.

Examples

symbol.url = "cat-1-hurricane.png";

// render SVG document as a PictureMarkerSymbol
symbol.url = "logo.svg";

width Property width Numberautocast Autocasts from Number|String

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

The maximum allowed width of a picture marker symbol is 200px. If you set any value higher than 200px, then the image will be scaled down to a width of 200px while preserving the aspect ratio of the image.

Default Value:12

Examples

// height in points
symbol.height = 14;

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

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

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(){PictureMarkerSymbol}

Creates a deep clone of the symbol.

Returns

Returns true if a named group of handles exist.

Parameter

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
