Since: ArcGIS Maps SDK for JavaScript 4.27

RasterBandInfo class provides additional information for each raster band in an image service referenced by ImageryLayer.serviceRasterInfo or ImageryTileLayer.serviceRasterInfo. A band is represented by a single matrix of pixel values, and a raster with multiple bands contains multiple spatially coincident matrices of pixel values representing the same spatial area. Image services can include information such as the band name, band index value, wavelength range, the radiance gain, radiance bias, and solar irradiance. All other raster datasets will only contain the band index value.

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. 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.

Parameters

Parameter	Type	Description	Required
json	`any`	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: any
Returns a new instance of this class.

clone

Method

Signature: clone (): RasterBandInfo

Creates a deep clone of the raster band info object.

Returns

RasterBandInfo

A deep clone of the object that invoked this method.

// Creates a deep clone of the layer.rasterInfo.bandInfos[0] let bandInfo = layer.rasterInfo.bandInfos[0].clone();

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
