LineLayer

A stroked line.

  • id
  • Whether this layer is displayed.

  • The display of line endings.

  • The display of lines when joining.

  • Used to automatically convert miter joins to bevel joins for sharp angles.

  • Used to automatically convert round joins to miter joins for shallow angles.

  • Sorts features in ascending order based on this value. Features with a higher sort key will appear above features with a lower sort key.

  • Blur applied to the line, in pixels.

  • Transition options for lineBlur.

  • The color with which the line will be drawn.

  • Transition options for lineColor.

  • 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 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.

  • Transition options for lineDasharray.

  • Draws a line casing outside of a line’s actual path. Value indicates the width of the inner gap.

  • Transition options for lineGapWidth.

  • Defines a gradient with which to color a line feature. Can only be used with GeoJSON sources that specify "lineMetrics": true.

  • 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.

  • Transition options for lineOffset.

  • The opacity at which the line will be drawn.

  • Transition options for lineOpacity.

  • Name of image in sprite to use for drawing image lines. For seamless patterns, image width must be a factor of two (2, 4, 8, …, 512). Note that zoom-dependent expressions will be evaluated only at integer zoom levels.

  • Transition options for linePattern.

  • The geometry’s offset. Values are [x, y] where negatives indicate left and up, respectively.

  • Transition options for lineTranslate.

  • Controls the frame of reference for line-translate.

  • The line part between [trim-start, trim-end] will be marked as transparent to make a route vanishing effect. The line trim-off offset is based on the whole line range [0.0, 1.0].

  • Stroke thickness.

  • Transition options for lineWidth.
