Constructors

RasterLayer({required String id, Visibility? visibility, double? minZoom, double? maxZoom, String? slot, required String sourceId, String? sourceLayer, String? rasterArrayBand, double? rasterBrightnessMax, double? rasterBrightnessMin, int? rasterColor, List<double?>? rasterColorMix, List<double?>? rasterColorRange, double? rasterContrast, double? rasterElevation, double? rasterEmissiveStrength, double? rasterFadeDuration, double? rasterHueRotate, double? rasterOpacity, RasterResampling? rasterResampling, double? rasterSaturation})

Properties

hashCode → int

The hash code for this object.

no setter, inherited

id ↔ String

The ID of the Layer.

getter/setter pair, inherited

maxZoom ↔ double?

The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.

getter/setter pair, inherited

minZoom ↔ double?

The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.

getter/setter pair, inherited

rasterArrayBand ↔ String?

Displayed band of raster array source layer

getter/setter pair

rasterBrightnessMax ↔ double?

Increase or reduce the brightness of the image. The value is the maximum brightness.

getter/setter pair

rasterBrightnessMin ↔ double?

Increase or reduce the brightness of the image. The value is the minimum brightness.

getter/setter pair

rasterColor ↔ int?

Defines a color map by which to colorize a raster layer, parameterized by the ["raster-value"] expression and evaluated at 256 uniformly spaced steps over the range specified by raster-color-range.

getter/setter pair

rasterColorMix ↔ List<double?>?

When raster-color is active, specifies the combination of source RGB channels used to compute the raster value. Computed using the equation mix.r * src.r + mix.g * src.g + mix.b * src.b + mix.a. The first three components specify the mix of source red, green, and blue channels, respectively. The fourth component serves as a constant offset and is not multipled by source alpha. Source alpha is instead carried through and applied as opacity to the colorized result. Default value corresponds to RGB luminosity.

getter/setter pair

rasterColorRange ↔ List<double?>?

When raster-color is active, specifies the range over which raster-color is tabulated. Units correspond to the computed raster value via raster-color-mix.

getter/setter pair

rasterContrast ↔ double?

Increase or reduce the contrast of the image.

getter/setter pair

rasterElevation ↔ double?

Specifies an uniform elevation from the ground, in meters. Only supported with image sources.

getter/setter pair

rasterEmissiveStrength ↔ double?

Controls the intensity of light emitted on the source features.

getter/setter pair

rasterFadeDuration ↔ double?

Fade duration when a new tile is added.

getter/setter pair

rasterHueRotate ↔ double?

Rotates hues around the color wheel.

getter/setter pair

rasterOpacity ↔ double?

The opacity at which the image will be drawn.

getter/setter pair

rasterResampling ↔ RasterResampling?

The resampling/interpolation method to use for overscaling, also known as texture magnification filter

getter/setter pair

rasterSaturation ↔ double?

Increase or reduce the saturation of the image.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

slot ↔ String?

The slot this layer is assigned to. If specified, and a slot with that name exists, it will be placed at that position in the layer order.

getter/setter pair, inherited

sourceId ↔ String

The id of the source.

getter/setter pair

sourceLayer ↔ String?

A source layer is an individual layer of data within a vector source. A vector source can have multiple source layers.

getter/setter pair

visibility ↔ Visibility?

The visibility of the layer.

getter/setter pair, inherited
