[mapserver-users] opacity and outputformat

[Marc-André Trottier]

hi!
how can i get a output with opacity on 2 or more layers.
with only 1 layer it's working fine but not with 2 or more.

How should be written OPACITY when using IMAGEMODE RGBA ? (ALPHA)
i tried something like OPACITY 22,22,22,22 but looks bad

in all my tests, all i got was my 2 layers with full opacity (100) ...

here is my mapfile :
