Class RasterImageModel`Abstract`

A model that can provide access to raster images. To visualize such a model in a RasterImageLayer.

There are two implementations: WMSImageModel.

Note that this is an "abstract" model and should never be instantiated directly. Only its subtypes can be directly instantiated.

RasterImageModel is not supported in hardware-accelerated map.

`Protected` constructor

new RasterImageModel(options?): RasterImageModel
Creates a new image model with the given options. This is an "abstract" model and should never be instantiated directly.
Parameters
- Optional options: RasterImageModelConstructorOptions
  parameters to configure the RasterImageModel.
Returns RasterImageModel
Overrides Invalidation.constructor

Accessors

`Abstract` bounds

get bounds(): Bounds
The Bounds by which the geometry of this Bounded object is bounded or null if the bounds is not defined.

Returns Bounds
Implementation of Bounded.bounds

coordinateType

get coordinateType(): CoordinateType
The coordinate type of geometries in this model

Returns CoordinateType
Implementation of Model.coordinateType

modelDescriptor

get modelDescriptor(): ModelDescriptor
An object containing metadata about this model

Returns ModelDescriptor
Implementation of Model.modelDescriptor
set modelDescriptor(modelDescriptor): void
An object containing metadata about this model
Parameters
- modelDescriptor: ModelDescriptor
Returns void
Implementation of Model.modelDescriptor

reference

get reference(): CoordinateReference
The reference in which this model is defined

Returns CoordinateReference
Implementation of Model.reference

Methods

invalidate

invalidate(): void
Signals that the underlying data for the tiled images has changed. If this model is added to a map using a RasterImageLayer, calling this method will thus trigger a refresh of the visualization.

Returns void
Overrides Invalidation.invalidate

Events

"Invalidated" event

on("Invalidated", callback: ((...args) => void), context?: any) : Handle
An event indicating that this Controller is invalidated. Invalidated means that data has changed and the visualization needs to be refreshed. This event fires when #invalidate is called.
Parameters
- event: "Invalidated"
- callback: ((...args) => void)
  - - (...args): void
    - Parameters
      Rest ...args: any[]
      Returns void
- Optional context: any
Returns Handle
Overrides Invalidation.on
