[Mapserver-users] HELP PLEASE URGENT!!, draw point in map

Tue Jan 13 10:09:18 EST 2004

I'm not positive on the syntax but I don't think the second $map->draw
is required because the point data is not actually bound as a data
source to the reddot layer and by doing the $map->draw after drawing the
point it is actually overrendering(word?) what $testpt->draw constructs.
Hopefully the syntax in:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex2
can be useful.
