Options used when rendering SimpleLine, SimplePolygon, CirclePolygon, LineString, MultiLineString, Polygon, and MultiPolygon objects in a line layer.

Extends

LayerOptions

Properties

blur	The amount of blur to apply to the line in pixels. Default 0.
lineCap	Specifies how the ends of the lines are rendered. `"butt"`: A cap with a squared-off end which is drawn to the exact endpoint of the line. `"round"`: A cap with a rounded end which is drawn beyond the endpoint of the line at a radius of one-half of the lines width and centered on the endpoint of the line. `"square"`: A cap with a squared-off end which is drawn beyond the endpoint of the line at a distance of one-half of the line width. Default `"round"`.
lineJoin	Specifies how the joints in the lines are rendered. `"bevel"`: A join with a squared-off end which is drawn beyond the endpoint of the line at a distance of one-half of the lines width. `"round"`: A join with a rounded end which is drawn beyond the endpoint of the line at a radius of one-half of the lines width and centered on the endpoint of the line. `"miter"`: A join with a sharp, angled corner which is drawn with the outer sides beyond the endpoint of the path until they meet. Default `"round"`.
offset	The line's offset. A positive value offsets the line to the right, relative to the direction of the line. A negative value offsets to the left. Default 0.
source	The id or instance of a data source which the layer will render.
sourceLayer	Required when the source of the layer is a VectorTileSource. A vector source can have multiple layers within it, this identifies which one to render in this layer. Prohibited for all other types of sources.
strokeColor	Specifies the color of the line. Default "#1E90FF".
strokeDashArray	Specifies the lengths of the alternating dashes and gaps that form the dash pattern. Numbers must be equal or greater than 0. The lengths are scaled by the strokeWidth. To convert a dash length to pixels, multiply the length by the current stroke width.
strokeGradient	Defines a gradient with which to color the lines. Requires the DataSource lineMetrics option to be set to true. Disabled if strokeDashArray is set.
strokeOpacity	A number between 0 and 1 that indicates the opacity at which the line will be drawn. Default 1.
strokeWidth	The width of the line in pixels. Must be a value greater or equal to 0. Default 2.
translate	The amount of offset in pixels to render the line relative to where it would render normally. Negative values indicate left and up. Default: [0,0]
translateAnchor	Specifies the frame of reference for translate. `"map"`: Lines are translated relative to the map. `"viewport"`: Lines are translated relative to the viewport Default: `"map"`

Inherited Properties

filter	An expression specifying conditions on source features. Only features that match the filter are displayed.
maxZoom	An integer specifying the maximum zoom level to render the layer at. This value is exclusive, i.e. the layer will be visible at maxZoom > zoom >= minZoom. Default 24.
minZoom	An integer specifying the minimum zoom level to render the layer at. This value is inclusive, i.e. the layer will be visible at maxZoom > zoom >= minZoom. Default 0.
visible	Specifies if the layer is visible or not. Default true.
