[Mapserver-users] extrange problem with colors and size in createLegendIcon

Hello Everybody,

I got the same legend Icon for two different line layers with different colors 
but with the SAME symbol and size, for example:

LAYER 1 with COLOR 0 0 255,  SYMBOL "circ" and SIZE 2 gives me an icon with 
color 0 0 255

LAYER 2 with COLOR 255 0 0,  SYMBOL "circ" and SIZE 2 gives me an icon with 
color 0 0 255  too!!!!

(With different size betwen layers the colors are OK)

I've been tried with different options, but I didn't find which can be the 
source of the problem.

Is it a bug o am I doing something wrong?

I simplified my code to show the problem, please try to reproduce and tell me:

<pre>
<?php
$map = ms_newMapObj("map.map");
$img = $map->draw();
$url = $img->saveWebImage(MS_PNG, 1, 1, 0);

$layer1=$map->getlayerbyname("1");
$layer2=$map->getlayerbyname("2");

$class1=$layer1->getclass(0);
$class2=$layer2->getclass(0);

$img1 = $class1->createLegendIcon($map->keysizex, $map->keysizey);
$img2 = $class2->createLegendIcon($map->keysizex, $map->keysizey);

$img1->saveImage("ima1.png", MS_PNG, 0, 0, 0);
$img2->saveImage("ima2.png", MS_PNG, 0, 0, 0);

print("Image 1: <img src=ima1.png>\n");
print("Image 2: <img src=ima2.png>\n")

?>
</pre>

map.map file:

 END
END

LAYER

 TYPE line
 DATA line1
 CLASS

  SYMBOL "circ"
  SIZE 2
 END
END

END
