[Cartoweb-users] Class attribute in raster query

[Simone Frigerio]

Hi all,
I inserted a raster layer (GRID) on mapfile and it is correctly visualized. Following raster query settings (return point feature with attributes) of mapserver I want to perform a query on it. The query work but give me back this list of value (it's correct):

x  y  value_list  value_n  red  green  blue 

The problem is that the tool doesn't insert the CLASS attribute (the name of the class the pixel is a member of). Only classified raster can visualize "class" attribute, and I performed a classification.
So can you give me what is the set up I forgot? Where I have to put a parameter to define an attribute "class" on query respond?
Regards
