Applies zoom level dependent scaling to all rendering properties including stroke width, bitmap patterns, and other styling parameters.

zoomlevel Target zoom level for scaling calculations Returns a new scaled polyline instruction

Implementation

@override
RenderinstructionPolyline forZoomlevel(int zoomlevel, int level) {
  RenderinstructionPolyline renderinstruction = RenderinstructionPolyline(level)
    ..renderinstructionScale(this, zoomlevel)
    ..baseSrcMixinScale(this, zoomlevel)
    ..bitmapSrcMixinScale(this, zoomlevel)
    ..strokeSrcMixinScale(this, zoomlevel);
  renderinstruction.id = id;
  return renderinstruction;
