WebMapServer PNG format scrambled for some servers
--------------------------------------------------
Key: UDIG-1391
URL: http://jira.codehaus.org/browse/UDIG-1391
Project: uDIG
Issue Type: Bug
Components: wms
Affects Versions: UDIG 1.2.M0
Reporter: Jody Garnett
Assignee: Jody Garnett
This issue appeared during testing on the windows platform...
1 Download from: http://udig.refractions.net/files/jre
2 Unzip into your udig folder
3. Start up udig and check either of the following:
- http://www.bsc-eoc.org/cgi-bin/bsc_ows.asp?version=1.1.1&service=WMS&request=GetCapabilities
- http://205.150.58.109/cgi-bin/bsc_ows.asp?version=1.1.1&service=WMS&request=GetCapabilities
4. In the default ordering PNG pictures will be requested; in whatever palette format we have trouble with
5. If the pictures appear scrambled try another JRE ..
Turns out this is a known problem with either JAI or ImageIO (I could not determine which); from email ...Andrea Aime said:

Yep, we noticed that in GeoServer as well, the native reader is quite
poor, that's why we disable it on startup with the following code:
ImageUtilities.allowNativeCodec("png", false, false);
Cheers

I would like to add this command to a startup hook:
- if I add it in net.refractions.udig.catalog.wms; it will make sense and the fix will be close to the plug-in having the problem
- if I add it in net.refractions.udig.core; it will be global for the entire application - along with all the other global settings
I think I will add it to net.refractions.udig.core; it is a global setting and should be documented as such....
