# Interface ImageServiceVectorLayerJson

The imageServiceVectorLayer displays pixel values as vectors. To do this, the image service layer must be a two-band raster in which one band holds magnitude values and one band holds direction values. The imageServiceVectorLayer also supports time-enabled data.

See https://developers.arcgis.com/web-map-specification/objects/imageServiceVectorLayer/.

Properties

### `Optional` blendMode

blendMode?:
| "invert"
| "normal"
| "lighter"
| "multiply"
| "color"
| "average"
| "color-burn"
| "color-dodge"
| "darken"
| "destination-atop"
| "destination-in"
| "destination-out"
| "destination-over"
| "difference"
| "exclusion"
| "hard-light"
| "hue"
| "lighten"
| "luminosity"
| "minus"
| "overlay"
| "plus"
| "reflect"
| "saturation"
| "screen"
| "soft-light"
| "source-atop"
| "source-in"
| "source-out"
| "vivid-light"
| "xor"

Blend modes are used to blend layers together to create an interesting effect in a layer, or even to produce what seems like a new layer.

Inherited from BasemapLayerJsonBase.blendMode

### `Optional` customParameters

customParameters?: Record<string, unknown>

A sequence of custom parameters appended to the URL of all requests related to supporting ArcGIS layer types.

### `Optional` definitionEditor

definitionEditor?: DefinitionEditorJson

Stores interactive filters.

### disablePopup

disablePopup: boolean

Boolean property indicating whether to ignore popups defined by the service item.

### `Optional` effect

effect?: EffectJson

Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work.

Inherited from BasemapLayerJsonBase.effect

### `Optional` id

id?: string

A unique identifying string for the layer.

Inherited from BasemapLayerJsonBase.id

### `Optional` isReference

isReference?: boolean

This is applicable if used as a baseMapLayer. A boolean value indicating whether or not the baseMapLayer draws on top (true) of other layers, including operationalLayers , or below (false).

Inherited from BasemapLayerJsonBase.isReference

### `Optional` itemId

itemId?: string

Optional string containing the item ID of the service if it's registered on ArcGIS Online or your organization's portal.

### `Optional` layerDefinition

layerDefinition?: LayerDefinitionJson

A layerDefinition object defining the attribute schema and drawing information for the layer.

### layerType

layerType

The type of layer.

Overrides BasemapLayerJsonBase.layerType

### `Optional` listMode

listMode?: LayerListMode

Indicates how the layer should display in the table of contents. The known values are listed below. See support/esri!ListMode.

Inherited from OperationalLayerJsonBase.listMode

### `Optional` maxScale

maxScale?: number

A number representing the maximum scale at which the layer will be visible. The number is the scale's denominator; thus, a value of 2400 represents a scale of 1/2,400. A value of 0 indicates that the layer will be visible no matter how far you zoom in.

Inherited from BasemapLayerJsonBase.maxScale

### `Optional` minScale

minScale?: number

A number representing the minimum scale at which the layer will be visible. The number is the scale's denominator; thus, a value of 2400 represents a scale of 1/2,400.

Inherited from BasemapLayerJsonBase.minScale

### `Optional` mosaicRule

mosaicRule?: MosaicRuleJson

Specifies the mosaic rule when defining how individual images should be mosaiced.

### `Optional` opacity

opacity?: number

The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.

Inherited from BasemapLayerJsonBase.opacity

### `Optional` refreshInterval

refreshInterval?: number

When the refresh interval is set on a layer, the client must refresh that layer only, not the entire web map. The default value is '0', meaning the no refresh. You can enable a refresh interval on the following types of layers: ArcGIS Server web service, hosted feature layer, hosted tile layer, OGC WMS, OGS WMTS, tile layer, GeoRSS, Living Atlas layers, basemaps (including Bing Maps basemaps), CSV from the web with latitude and longitude fields, and KML when added to ArcGIS Online through the My Content page. See https://doc.arcgis.com/en/arcgis-online/create-maps/set-refresh-interval.htm.

Inherited from OperationalLayerJsonBase.refreshInterval

### `Optional` showLegend

showLegend?: boolean

Indicates whether to allow map authors the ability to control what layers should be shown in a client's legend.

Inherited from BasemapLayerJsonBase.showLegend

### `Optional` timeAnimation

timeAnimation?: boolean

This property is applicable to layers that support time. If 'true', timeAnimation is enabled.

### `Optional` title

title?: string

A user-friendly title for the layer that can be used in a table of contents. If this is not included, then a title is derived from the service.

Inherited from BasemapLayerJsonBase.title

### `Optional` type

type?: LegacyOperationalLayerJsonType | LegacyBasemapLayerJsonType

(Deprecated, use layerType instead.) If the layer is referenced through a URL, but is not an ArcGIS web service, then this parameter can be supplied to denote the layer type.

Inherited from BasemapLayerJsonBase.type

### url

url: string

The URL to the layer.

### `Optional` visibility

visibility?: boolean

Determines whether the layer is initially visible in the web map.

Inherited from BasemapLayerJsonBase.visibility

### `Optional` visibilityTimeExtent

visibilityTimeExtent?: [number, number]

Represents time extent that will control when a layer should be visible based on webmap's current time. Visibility time extent only affects the layer visibility and will not filter the data.

Inherited from BasemapLayerJsonBase.visibilityTimeExtent
