[mapserver-users] COMPOSITE opacity

[Moretti Edmar]

Hi Thomas.

Unfortunately I can not compile MapServer. I use versions available for
Ubuntu 15-10. I develop software called i3Geo, which is based on MapServer
and PHP-MapScript and many people use the available versions with "apt-get
install ..." to prepare the web server.
The solution I found was to use OPACITY for classes instead of layers, but
it is not a good solution.

Another problem: when I use cgi-bin/mapserv and COMPOSITE OPACITY
everything works, but only for OPACITY, other filters do not work.

I tested with this mapfile (cgi-bin/mapserv?map=...&mode=map ):

END
