[ka-Map-users] setting transparency for a layer

[T.Hens at bjoernsen.de]

Dear List, 
also the problem tranparency is already listed, i did not get a solution for my problem. I have to draw a polygon shape with transparency 50 over a raster dataset. In Chameleon it works fine for FireFox and IE, but the same map file in ka-map causes problems in IE: only the raster layer is visible, the 50% transparent polygons are not visible.
I tried to use gif output, but transparency of 50% did not work in Firefox and IE, the polygons were drawn, but without transparency.
I use the following settings in the Mapfile 
OUTPUTFORMAT 
NAME PNG 
DRIVER "GD/PNG" 
MIMETYPE "image/png" 
IMAGEMODE RGBA 
EXTENSION "png" 
FORMATOPTION "INTERLACE=ON" 
TRANSPARENT ON 
END 
... 
LAYER 
NAME "Wassertiefe HQ 100" 
GROUP "Wassertiefe" 
STATUS ON 
DATA "wt/wt_hq100" 
TYPE POLYGON 
CLASSITEM "wtiefe" 
UNITS METERS 
SIZEUNITS PIXELS 
TOLERANCE 0 
TOLERANCEUNITS PIXELS 
TRANSPARENCY 50 
TEMPLATE "foo" 
METADATA 
"WMS_TITLE" "Wassertiefe HQ 100" 
"WMS_ABSTRACT" "Wassertiefe bei HQ 100, Abfluss 1200 m³/s" 
END 
END 
What can i do to get the polygons 50% transparent in IE and Firefox? 
Best regards, 
Thorsten
