[mapserver-users] label placement problem

[Raivo Alla]

Hey,

is it possible that the reason why this feature is not implemented in
Mapserver is cause it demands too much computation resource and Mapserver
assumes that those kind of issues will be dealt before... modifying data
structure maybe?
Deleting all the duplicate address points for each building complex and
leaving only one (I do not prefer that)?

Cause for me it seems quite a common problem one should face in case he
needs to display building numbers.
Since there could be many buildings closely together at the crossings of the
streets, I seek some way to display them decently -
ie. showing label ("2") for buildings that are located at the street "Mündi"
and other label "2" for buildings at the street "Saiakangi"
so that Mapserver does not "see" the labels being identical.


Still full of hope,
Raivo
