First, Thanks for answer.
I found another way to do this that is not explain in the documentation.
We can set the labelangleitem with mapscript to :
$layer->set("labelangleitem","(angle*-1)");
This works for me. So maybe it can be part of the documentation ?
Does the subquery method is still using the indexes of the table (I
don't think so) ?
Thanks

you can use a custom query on your database
DATA "the_geom from
(SELECT gid, nom, the_geom, (-angle) AS inv_angle FROM troncon_route)
as foo using unique gid"
and then use
ANGLE [inv_angle] in your label block

Hello,
I want to invert the sign of the field I want to use in
layer->labelangleitem.
I don't want to it in the database because the information are sent by gps.
I want to know if it's possible do it on the fly with mapscript and how
(expression in the labelangleitem property ???) ?
Thanks
Steff
