[mapserver-users] Changing Point style on-the-fly

[Paul Spencer]

If you are using MapServer 5.0 or the brand new 5.2 then you can  
probably use attribute binding, which allows you to specify an  
attribute in your data as the source for various parameters in the map  
file.  For instance, if you have a field in your database called  
point_size that has a size value then you can do this:

SIZE [point_size]

You can also bind to COLOR and most other attributes inside STYLE and  
LABEL.  I just went to look for documentation on attribute binding and  
I can't seem to find anything beyond the original rfc (http://mapserver.gis.umn.edu/development/rfc/ms-rfc-19 
) so if you are running into trouble, don't hesitate to ask the  
developers :)

Cheers

Paul
