### Properties

[colorramp?](#colorramp) [id?](#id) [lineColor?](#linecolor) [lineColorTen?](#linecolorten) [lineThickness?](#linethickness) [opacity?](#opacity) [renderBlurRadius?](#renderblurradius) [smooth?](#smooth) [stepForZoomLevels?](#stepforzoomlevels)

## Properties

### `Optional`colorramp[](#colorramp)

colorramp?: [ColorRamp](https://docs.maptiler.com/sdk-js/modules/weather/api-reference/classes/ColorRamp/)

Coloramp to use

### `Optional`id[](#id)

id?: string

ID of the layer

### `Optional`lineColor[](#linecolor)

lineColor?: [RgbaColor](https://docs.maptiler.com/sdk-js/modules/weather/api-reference/types/RgbaColor/)

Lines color

### `Optional`lineColorTen[](#linecolorten)

lineColorTen?: [RgbaColor](https://docs.maptiler.com/sdk-js/modules/weather/api-reference/types/RgbaColor/)

Line color for pressure that are multiples of 10 (980, 990, 1000, etc.)

### `Optional`lineThickness[](#linethickness)

lineThickness?: number

Thickness of the line. Default `1.0`.

### `Optional`opacity[](#opacity)

opacity?: number

Opacity of the layer in \[0, 1\]

### `Optional`renderBlurRadius[](#renderblurradius)

renderBlurRadius?: number

Integer > 0. Blurring is needed to ensure smoothly curved lines. [renderBlurRadius](#renderblurradius) is used in every animation frame to get best result, but higher values can make animation slower.

### `Optional`smooth[](#smooth)

smooth?: boolean

Whether or not the colorramp must be smooth

### `Optional`stepForZoomLevels[](#stepforzoomlevels)

stepForZoomLevels?: [ZoomLevelStep](https://docs.maptiler.com/sdk-js/modules/weather/api-reference/interfaces/ZoomLevelStep/)\[\]

Lines densities for zoom levels
