[mapserver-users] dynamic labeling

[Alexander Shostko]

Dear Mapserver Users!

1. Thanks in advance for help and suggestions. I need to 
dynamically turn labels on/off the map when 
certain events happen (attributes are changed in dbf file). 
I set the colors dynamically already (I introduced an extra 
field in dbf file 
and use expression statement to change the color ) 

Can I use the same EXPRESSION statements to turn the labels 
on/off based on certain dbf fields values?  

Do the labels scale in size when the map is scaled ? Do I need 
php/mapscript or I can use straight CGI module ?


 Any pointers to examples are appreciated.


2. Also any chance to prezoom the image when displaying it the 
first time (appear too small and 
changing the extent parameters does not do much )


Thanks again
