[mapserver-users] style level opacity issue

[Huotari, John B (RCIS)]

I’d likewise like to see an answer to this as I’ve thus far been unable to make opacity work at the style level.  I’ve worked around that by using the opacity at the layer level instead, which might be a suitable solution in your situation.

Subject: [mapserver-users] style level opacity issue


I'm trying to render a single vector layer that has overlapping polygons, but I cant seem to get the settings correct for what I want. There are overlapping polygons on the layer, and I would like them to each be drawn transparently so that I can see the overlapping regions. However, no matter what I try I can't seem to get this effect and the rendering will make the shapes draw over each other.



I'm using Mapserver 6.0.1



OUTPUTFORMAT

NAME "png"

DRIVER AGG/PNG

MIMETYPE "image/pngt"

IMAGEMODE RGBA

EXTENSION "png"

FORMATOPTION "GAMMA=1.0"

TRANSPARENT TRUE

END



I have a very simple class for my layer
