<P><FONT SIZE=2 FACE="Arial">Dear List,</FONT><FONT FACE="Times New Roman"> </FONT>
<BR><FONT SIZE=2 FACE="Arial">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.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I tried to use gif output, but transparency of 50% did not work in Firefox and IE, the polygons were drawn, but without transparency.</FONT></P>
