[Geomoose-users] roads layer is not transparent in IE6 AGG renderer

[Dan Little]

Complain to Microsoft. :)

AGG renders PNGs in a way that is not compatible with IE6.  This is not a GeoMOOSE problem, this is not a Mapserver problem, this is a Microsoft problem, and a problem of using 7 year old software.

Subject: [Geomoose-users] roads layer is not transparent in IE6 AGG renderer

 
Hi,
 
 
When using IE6 as a client it appears that my roads layer is
not transparent, Instead I see a gray background under my roads.  I am
using AGG as a rendered for roads.  Is this a problem with IE 6, a bug
with AGG, or could something be incorrect with my .map file?
 
Also,
A while ago I noticed that when using the AGG reindeer the legend
text does not display.  Has anyone found a workaround for this?  Has
it been fixed in 1.6 (I haven’t tried 1.6 yet).
 
Thanks
