[Geoserver-users] Transparent argument and Geoserver errors

GeoServer GeoServer User

Good Day List,

Currently having an issue making a request to Geoserver using the Transparent argument. I currently have a list of image mosaic raster layers which are all generated the same way and added to geoserver the same way but yet only one works with ‘transparent=true.’

So that was convoluted. Anyway, make a WMS request and I get back an image.
Example: http://localhost:8080/geoserver/ENV-792B/wms?service=WMS&version=1.1.0&request=GetMap&layers=ENV-792B:300mb_For_Guppy&styles=&bbox=47.968125,23.989358857500005,64.968125,39.989358297500004&width=512&height=481&srs=EPSG:4326&format=image%2Fpng

Works Great, everybody happy.

Now I make a the same request with &transparent=true at the end and boom: java hates me and kicks me in the balls (Short copy below and GeoserverError.txt attached is the full request and error):

java.lang.RuntimeException: - Unable to render RenderedOp for this operation.

Hmmm, unfortunate. Well for grins I was messing around testing and tried http://localhost:8080/geoserver/ENV-792B/wms?service=WMS&version=1.1.0&request=GetMap&layers=ENV-792B:300mb_For_Guppy,ENV-792B:300mb_For_Guppy&styles=&bbox=47.968125,23.989358857500005,64.968125,39.989358297500004&width=512&height=481&srs=EPSG:4326&format=image%2Fpng&transparent=true which is the same request just with the exact same layer twice and it works. Transparency works. Everyone is happy. I am using the default raster SLD that ships with geoserver but for grins I have gone through and changed it slightly to use use an opacity of 0.99 and no difference. I’m at a complete loss. Please tell me I’m doing something stupid and this is an easy fix.

Thank you for your time.

Please open a bug report on jira.codehaus.org, attach enough sample data to
reproduce the error, and the request that makes it fail

Cheers

Wow, that's bad! Which java version are you using? Mine just throws
exception, it never kicked where it was not supposed to; you might
want to conside changing version :wink:

The error looks strange indeed. As Andrea suggested it would be great
if you could open a Jira report with some sample data.
You might even to try and disable accelerated rendering with
-Dorg.geoserver.render.raster.direct.disable=true and see what happen.
