Re: [udig-devel] Transparency support WMS Renderer with image/png8 format
|
Right. I moved image/png to the top of the list and it works for me. Otherwise with the attached patch I changed the renderer and it works with the default order too.
I created an issue :
http://jira.codehaus.org/browse/UDIG-1650

Create a bug - and attach a patch if you can :-)
Can you confirm, by changing the requested format order in the WMS preference page; that switching to a different format is helping?

Hello uDig'ers
I just tested a bit udig 1.2 RC2 against a geoserver 2.0.x server and was wondering that requested layers returned images with a default background color. The request has "TRANSPARENCY=FALSE" included and therefore I looked into the sources.
In the
BasicWMSRenderer2 class I found a formatSupportsTransparency function that would return false if the image format is image/png8. In addition the udig default image type order has this format on top of others, means if the server supports image/png8 udig will request this format.
In my opinion it looks like a bug, png8 has transparency support [1]! Should I create an issue in jira and attache a patch there. Could somebody confirm that? The formatSupportsTransparency function should return true if the format is image/png8 !
In regards,
Frank
