Properties
Specifies the lengths of the alternating dashes and gaps that form the dash pattern. The lengths are later scaled by the line width. To convert a dash length to density-independent pixels, multiply the length by the current line width. Note that GeoJSON sources with lineMetrics: true specified won't render dashed lines to the expected scale. Also note that zoom-dependent expressions will be evaluated only at integer zoom levels. The unit of lineDasharray is in line widths.
The line's offset. For linear features, a positive value offsets the line to the right, relative to the direction of the line, and a negative value to the left. For polygon features, a positive value results in an inset, and a negative value results in an outset. The unit of lineOffset is in density-independent pixels.
The fade range for the trim-start and trim-end points is defined by the {@link PropertyFactory#lineTrimOffset} property. The first element of the array represents the fade range from the trim-start point toward the end of the line, while the second element defines the fade range from the trim-end point toward the beginning of the line. The fade result is achieved by interpolating between {@link PropertyFactory#lineTrimColor} and the color specified by the {@link PropertyFactory#lineColor} or the {@link PropertyFactory#lineGradient} property.
