PolylineAnnotationManager

An instance of PolylineAnnotationManager is responsible for a collection of PolylineAnnotations.

  • The collection of PolylineAnnotations being managed

  • Synchronizes the backing source and layer with the current annotations and common layer properties. This method is called automatically with each display link, but it may also be called manually in situations where the backing source and layer need to be updated earlier.

  • The display of line endings.

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

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

  • 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.

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

  • 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].
