G'day all,
using mapserver 5.4 as a WMS server (to an openlayers application) I
don't seem to be able to get any scaling of labels.
If I set SIZE 10, they are 10 pixel. If I don't set any size params,
they are 4. If I set minsize, they are minsize (but the ALIGN is
poor). if I set minsize 8 and size 10, they are size 10 and the ALIGN
is pretty good.
I'm actually projecting a network graph, so it would be good to be
able to see the priority labels when zoomed out, and the others when
zoomed in, but at a legible (and sensible) size.
I'm not sure where to start - is it MapServer, WMS, OpenLayers, or a
false sense I had that this was how it should work...
cheers
Ben
