Properties

filter ↔ List<Object>?
Expression specifying conditions on source features. Only features that match the filter are displayed.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
id ↔ String
The ID of the Layer.
getter/setter pairinherited

Minimum zoom level. At zoom levels less than this, the layer is hidden. Range: 0 to 24.
getter/setter pairinherited
rasterArrayBand ↔ String?
Displayed band of raster array source layer. Defaults to the first band if not set.
getter/setter pair
rasterArrayBandExpression ↔ List<Object>?
Displayed band of raster array source layer. Defaults to the first band if not set.
getter/setter pair
rasterBrightnessMax ↔ double?
Increase or reduce the brightness of the image. The value is the maximum brightness. Default value: 1. Value range: 0, 1
getter/setter pair
rasterBrightnessMaxExpression ↔ List<Object>?
Increase or reduce the brightness of the image. The value is the maximum brightness. Default value: 1. Value range: 0, 1
getter/setter pair
rasterBrightnessMin ↔ double?

getter/setter pair
rasterBrightnessMinExpression ↔ List<Object>?
Increase or reduce the brightness of the image. The value is the minimum brightness. Default value: 0. Value range: 0, 1
getter/setter pair
rasterColor ↔ int?
Defines the color ramp used to colorize a raster layer, parameterized by the ["raster-value"] expression and evaluated over the range specified by raster-color-range. Raster values are spaced evenly across the range by default.
getter/setter pair
rasterColorExpression ↔ List<Object>?
Defines the color ramp used to colorize a raster layer, parameterized by the ["raster-value"] expression and evaluated over the range specified by raster-color-range. Raster values are spaced evenly across the range by default.
getter/setter pair
rasterColorMix ↔ List<double?>?
When raster-color is active, specifies how the raster value is computed from a non-rasterarray source's channels, using the equation mix.r - src.r + mix.g - src.g + mix.b - src.b + mix.a. The first three components weight the source's red, green, and blue channels; the fourth is a constant offset and is not multiplied by source alpha. Source alpha is carried through and applied as opacity to the colorized result. The default corresponds to RGB luminosity. rasterarray sources ignore this property, as their raster value is decoded directly from the source data. Default value: 0.2126,0.7152,0.0722,0.
getter/setter pair
rasterColorMixExpression ↔ List<Object>?

getter/setter pair
rasterColorRange ↔ List<double?>?
When raster-color is active, specifies the range of raster values mapped onto the color ramp, from the start of the ramp (low bound) to its end (high bound). For rasterarray sources the raster value is the decoded source data in the source's own units, and the source's stated data range is used when this property is unspecified. For other raster sources the raster value is computed from the source's channels via raster-color-mix. Defaults to [0, 1] when no range is otherwise available.

For other raster sources the raster value is computed from the source's channels via raster-color-mix. Defaults to [0, 1] when no range is otherwise available.
