Hi Peter,
Nope, separating Graphic and Label elements in 2 different rules would of
course handle well the relative displacement but wouldn’t manage the labels
overlapping.
The labels overlapping is the main reason of using both Graphic and Label in
the same rule: it ensures that each Label is drawn over a Marker, then also
avoids the overlapping of different pairs Marker+Label.
My particular requirement is to have:
- a pair Marker+Label for each point
- pairs Marker+Label shall not overlap when zooming the map
- the Marker is centered on the point geom (X,Y)
- the Label is centered on the point geom (X+DELTAX,Y)
Something similar with the well-known case of roads shields (the road number in
the middle of a road marker) but where the road number is not centered on the
marker but it is written on the right side of the marker.
Did someone already find a solution to this?
Thanks,
Victor
