I have a base map image, and I want to be able to add markers to this map. Markers are controlled by a set of buttons at the bottom of the screen and should be able to show and hide whenever the user selects. I need to be able to scale the map, and the markers should stay in the right place. Getting multiple layers for display is not a problem, but scaling.
Does anyone know how I can scale multiple layers while still being able to hide and display markers at any given time?
