Properties

channel

open override var channel: SampleChannel

channels

open override var channels: List<ColorBand>

colorScale

open override var colorScale: ColorScaleOptions

A ColorScale maps numeric values to a color palette. The scale can then be used to generate a set of colors for a given range of values and options.

drawRange

open override var drawRange: ClosedRange<Double>?

Limits the data range that should be rendered from the sampled data. If not provided, then the full data range provided by the associated data source will be rendered by default.

expression

open override var expression: SampleExpression

Determines how data should be sampled from the encoded data texture.

interpolation

open override var interpolation: InterpolationMode

Type of interpolation to perform on the data.

meld

var meld: Boolean

multiband

var multiband: Boolean

offset

open override var offset: Float

Normalized amount to shift the interpolated sample values from 0 to 1. This is typically used for expression operations like diff where interpolated values can be negative and you need to start values half way (0.5) between the colorscale.range.

opacity

open override var opacity: Float

Opacity of the rendered data from 0 (full transparent) to 1 (fully opaque).

quality

open override var quality: DataQuality

ntrols the data resolution that gets requested by the layer’s data source and rendered to the map. Data will be interpolated when rendering to the map to ensure low resolution/quality data is still smooth.

smoothing

open override var smoothing: Float

Amount of smoothing to apply on the data from 0 (no smoothing) to 1 (full smoothing). Increasing this value is useful for low resolution data sets or when higher detail is not desired or needed.
