Hi ,
Can anyone tell me if they are experiencing any issues with the transparency in GS-RC1?
It seems that the “White” in a vector layer, still displays data from another layer (for example a raster) that is underneath it, regardless if TRANSPARENT=TRUE or FALSE.
Could this be the default behaviour for GIF and PNG if the polygon does not have a fill associated in the corresponding SLD?
Thanks,
Steve

That sounds odd to me. Can we see the sld?

Hey there. So I found some time to try and replicate but failed.
Take the following request for example:
It has a raster layer and then on top of usual polygon style, which is opaque, and there
is no way to see through the polygons.
I guess it may be something specific to you request, I don’t see anything particular in the SLD
you provided that would make colors translucent.
If you can extract some data for the two layers in shapefiles, provide the two styles as well,
and attach everything to a bug report on jira.codehaus.org, that should allow us to reproduce
the issue.
Just a wild idea though… did you say sometimes ago that you modified GeoServer to render
multiple layers in parallel? In that case I guess you have each layer rendered on a different
BufferedImage, when merging them translucency might be induced by using the wrong
type of AlphaComposite. Just a shot in the dark, might be relevant, might be totally off
the mark.
Cheers
