Please write a bug against this for mapscript.
It might end up being a doc bug but setting the color -1,-1,-1 means to
make the object transparent. For example you would use this for the
color of a polygon to make it transparent and then could set the border
to black to highlight the edge of the polygon with out over writing the
actual polygon.

Sorry for previous incomplete message
Luca,
I discovered that when tou set
$style->color->setRGB( -1,-1,-1);
nothing appears,
instead if you set
$style->color->setRGB(0,0,0);
works!
Evidently MS does not consider a valid color the RGB( -1,-1,-1), only a
mapfile annotation, and does not save it when invoking $map->save().
ciao

Hi Pietro and thx for your answer!
This is the code i use for creating the new class:
$class = ms_newClassObj($layer);
$class->setExpression("'[pixel]' EQ '1'");
$style = ms_newStyleObj($class);
$style=$class->getStyle(0);
$style->color->setRGB( -1,-1,-1);
And this is the debug mapfile:
CLASS
EXPRESSION "'[pixel]' EQ '1'"
METADATA
END
STYLE
ANGLE 360
SYMBOL 0
END
END
What i am doing wrong?
Thanks
Luca

Luca,
I had a similar problem.
Try:
....
$style=$class->getStyle(0);
$style->color->setRGB( -1,-1,-1);
In other words you must get the reference of the existing Style from
the Class.
I made so, and works... - I don't know because :) -
ciao

Hi to all!
I am trying to create a new layer using php/mapscript; the problem is
for
the class section:
this is the mapfile sample i'd like to crete:
CLASS
EXPRESSION "1"
STYLE
COLOR -1 -1 -1
END
END
And this is the mapscript i have written:
$class = ms_newClassObj($layer);
$class->setExpression("'[pixel]' EQ '1'");
$style = ms_newStyleObj($class);
$style->color->setRGB( -1,-1,-1);
Debugging the mapfile, the CLASS it's been created, but not the style
of
the class.
Thanks very much
Luca
