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.

Optionaleffect

effect?: EffectJson

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

Optionalid

id?: string

A unique identifying string for the layer.

OptionalisReference

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).

OptionallayerType

layerType?: LayerJsonType

Type of the layer.

OptionalmaxScale

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.

OptionalminScale

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.

Optionalopacity

opacity?: number

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

OptionalshowLegend

showLegend?: boolean

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

Optionaltitle

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.

Optionaltype

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.

Optionalvisibility

visibility?: boolean

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

OptionalvisibilityTimeExtent

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.
