[Mapserver-users] Symbols in mapserver

[Till Adams]

Dear Ballini,

it is not possible to rotate symbols in mapserver, but it is possible to 
do this with labels. So you need a labelitem, which is the letter from 
your Ttf to display the symbol and a "labelangleitem" field with the 
angle of the rotation as value.

Looks like this:
LAYER
   NAME '...'
   ...
   CLASSITEM 'anitem'
   LABELITEM 'label'
   LABELANGLEITEM 'angle'
    CLASS
     NAME '...'
     EXPRESSION /./
     LABEL
      TYPE TRUETYPE
      FONT "aFont"
      SIZE 18
      COLOR 255 0 0
     END
    END  # CLASS
END # END LAYERFILE

Cheers,

Till
