[mapserver-users] Changing IMAGECOLOR with PHP MapScript

[Hankley, Chip]

OK,

I tried this
  ($map is passed)
  $bgcolor = $map->addcolor(238,238,238);
  $map->set("imagecolor", $bgcolor);

...and now I get the following error:

Fatal error: Property 'imagecolor' does not exist in this object. in
c:\inetpub\wwwroot\seating\seating.php on line 567

Any ideas?

Chip

I think you have to add a colour first before you try to set its
property (see the MapObject Class and its members in
http://mapserver.gis.umn.edu/doc/phpmapscript-class-guide.html#MapObj),
such as the following:

$color = $map->addcolor(0,0,0);
$map->set("imagecolor", $color);
