StrokePaint

Stroke style shared by line-capable paint types (for example LineLayerPaint, FillLayerPaint.stroke, and CircleLayerPaint.stroke).

On FillLayerPaint, outline width is emitted on a companion line style layer ({layerId}::stroke) because Mapbox fill layers have no width property. thickness of 0 maps to a thin ~0.5px line (half of the old fill-outline-color edge). Larger values are scaled by FillLayerPaint.OUTLINE_WIDTH_SCALE.

Values are mapped to Mapbox-style line properties where applicable:

• color ->line-color (fill outlines use companion ::stroke line layer)

• opacity ->line-opacity

• thickness ->line-width (fill outlines scaled by FillLayerPaint.OUTLINE_WIDTH_SCALE)

• lineJoin ->line-join

• lineCap ->line-cap

• miterLimit ->line-miter-limit

For GLES stencil line masks, lineJoin, lineCap, and miterLimit are also consumed by the ribbon mesh builder to approximate Mapbox/JS line appearance.

Example:

val stroke = StrokePaint().apply {
    thickness = StyleValue.Constant(5.0)
    lineJoin = StyleValue.Constant(LineJoin.MITER)
    lineCap = StyleValue.Constant(LineCap.ROUND)
    miterLimit = StyleValue.Constant(2.0)
}
