ArcGIS Runtime's built-in selection tool highlights the item with a halo around the symbol. This function has no public API for customization beyond color. I'm interested in dynamically creating a custom halo around symbols at runtime (A custom function or capability to separate the selection process from the visual halo display).
Is it feasible to:
Extract vector geometry from multilayer CIM symbols (.stylx files) using Runtime APIs and dynamically buffer them to create a halo?
- Alternatively, pre-author halos directly into symbols within ArcGIS Pro (as additional polygon layers), and then toggle their visibility at runtime via some sort of isEnabled property?
Any insights on feasibility, performance, or recommended approaches are appreciated.
