SignpostImg class Maps & 3D Scenes
Vector signpost image for directional navigation signs.
SDK-generated vector image representing directional road signs (exit signs, destination boards, etc.) in navigation UI. Supports lossless scaling to any size (isScalable returns true). Cannot be instantiated by users - only provided via SignpostDetails.image in navigation instructions.
Customize appearance using SignpostImageRenderSettings to control layout
(border width, row height, max rows). Set allowResize to true to let the SDK
choose optimal aspect ratio based on requested height.
