[Geomoose-users] Poor quality WMS display in IE

[Bistrais, Bob]

Brent- you are a genius!!  I removed the opacity setting for the WMS in
mapook.xml, and now it's looking correct in IE8.

 

Thanks!

Bob

Bob,

  Check your  "opacity" setting for the WMS <map-source> in your map
book and set it to 100 (or remove it).  As Michael points out, IE has
problems using both Alpha (a band in the image) and transparency (a
setting in the browser) for a PNG image.



Best Regards,
Brent Fraser

I'm using a WMS service of our base data in a GeoMoose application.  The
WMS is at MapServer 6.0.1 with a PNG output type.  My GeoMoose
installation is the Oregon variant 2.2 (MapServer 5.6?).

 

This service looks poor in the application when in Internet Explorer
(version 8), but looks great in Firefox, Chrome, and Safari.  The WMS
also looks fine in ArcGIS, and also in IE with a simple WMS GetMap
request. 

 

Right now, the WMS service and my app are on our test server, which you
should be able to look at.  I will give you the caveat that the
application is still being built and many controls are not yet working,
but if anyone wants to take a look, here are the URLs:

 

WMS Service:

http://mapservertest.maine.gov/wms/mapserv.exe?map=c:/wms/basemapNew.map
&SERVICE=WMS&     -WMS version 1.1.1

 

Here is the URL for the simple WMS request I tried, and looks OK in IE:

http://mapservertest.maine.gov/wms/mapserv.exe?map=c:/wms/basemapNew.map
&SERVICE=wms&version=1.1.1&request=GetMap&layers=towns24_poly,Roads,Hydr
ography&BBOX=437700,4907800,439030,4909100&SRS=EPSG:26919&FORMAT=image/p
ng&width=800&height=600

 

GeoMoose Application:

http://mapservergeotest.maine.gov/broadband/index.html#
<http://mapservergeotest.maine.gov/broadband/index.html>    -Zoom in on
a town and you will see poor graphic quality in IE, but looks good in
other browsers.

 

 

But what could be causing the poor display only with IE?  Could it be
OpenLayers causing the problem?  Other ideas?  Has anyone else had this
experience?  Is there some setting on IE that I need to adjust?

 

Thanks,

Bob
