Topic: How to determine the 2d pixel size of a 3d marker
Hi
We want a 3d marker to be always visible in the map area and we use an auto zoom function for this. As the position of the marker is set at its bottom, we want to zoom out, when the top of the marker leaves the top of the map, and not when its position (bottom of marker) leaves the map.
For this, we need to determine the 2d pixel height of the marker (which ist always constant).
Does anyone know how to do this?
Many thans.
