[Mapserver-users] Hwo to change OVERLAYSIZE from perl/php?

[Hermann-Marcus Behrens]

Hello,

I'm using the new mapserv/mapscript 4.2 and I would
like to access OVERLAYSYMBOL and OVERLAYSIZE from within mapscript with 
perl.

Is this not possible anymore? I tried to change the values with 
"classObj" and "styleObj", but
both attempts failed.

I need OVERLAYSIZE to change dynamically the "border" around polylines 
for streets.
Before OVERLAYSYMBOL etc. were introduced, I drew the streets twofold,
once a little bit thicker and in a darker color and the second time 
thinner with a lighter color.

Is this a reasonable way to create borders around polylines?
