Hi Nikolaos,
the values seem a bit rigid to me... what about giving all the quadrant
positions
a name, and then allow the user to provide a comma separated list of
positions
that they want the engine to try instead?
Did you check what desktop applications like ArcGIS or QGIS do? Would be
interested not to steer too far away from that as both systems have
converters
from their styling language to GeoTools own SLD (without getting crazy with
extra work, of course!)
Cheers
Andrea
