Properties

filter ↔ List<Object>?
An expression specifying conditions on source features. Only features that match the filter are displayed.
read / writeinherited
hashCode → int
The hash code for this object.
read-onlyinherited
id ↔ String
The ID of the Layer.
read / writeinherited
maxZoom ↔ double?
The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.
read / writeinherited
minZoom ↔ double?
The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.
read / writeinherited
rasterArrayBand ↔ String?
Displayed band of raster array source layer. Defaults to the first band if not set.
read / write
rasterArrayBandExpression ↔ List<Object>?
Displayed band of raster array source layer. Defaults to the first band if not set.
read / write
rasterBrightnessMax ↔ double?
Increase or reduce the brightness of the image. The value is the maximum brightness. Default value: 1. Value range: 0, 1
read / write
rasterBrightnessMaxExpression ↔ List<Object>?
Increase or reduce the brightness of the image. The value is the maximum brightness. Default value: 1. Value range: 0, 1
read / write
rasterBrightnessMin ↔ double?
Increase or reduce the brightness of the image. The value is the minimum brightness. Default value: 0. Value range: 0, 1
read / write
rasterBrightnessMinExpression ↔ List<Object>?
Increase or reduce the brightness of the image. The value is the minimum brightness. Default value: 0. Value range: 0, 1
read / write
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.
read / write
rasterColorExpression ↔ List<Object>?
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.
read / write
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. Default value: 0.2126,0.7152,0.0722,0.

read / write
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. For rasterarray sources, if raster-color-range is unspecified, the source's stated data range is used.
