[Mapserver-users] How to make a legend

[Lowell Filak]

I'm not sure if this is exactly what your looking for but to generate the simplest legend you just need to adjust the settings for the legend of an existing mapObj, create the temporary file name, and save the image.
Example:
$map->{legend}->{label}->{color} = $map->addColor(0, 0, 89);
$map->{legend}->{label}->{size} = $mapscript::MS_MEDIUM;
$map->{legend}->{width} = 18;
$map->{legend}->{height} = 12;
($sec,$min,$hr,$mdy,$mnth,$yr,$wdy,$ydy,$isdst) = localtime;
$spid = $$;
$img = $map->drawLegend();
$img->saveImage("<temp_directory>/keys/$hr$min$sec$spid.png",$mapscript::MS_PNG,$map->{transparent},$map->{interlace},0);
