LaneImg class Images
Vector lane guidance image for navigation instructions.
SDK-generated vector image showing lane guidance arrows and markings for turn-by-turn navigation. Supports lossless scaling to any size (isScalable returns true). Cannot be instantiated by users - only provided by the SDK through navigation NavigationInstruction.laneImg and
Customize appearance using LaneImageRenderSettings to control colors for
active/inactive lanes and background. Set allowResize to true to let the SDK
choose optimal aspect ratio based on requested height.
