I need a better solution than just increasing my extents... I understand that the "black"/shadow areas are occurring outside my area of extents, but they shouldn't. Those should just be normal tiles without an overlay. If I increase my extents, with the area sizes I am dealing with, then I am going to have a huge cache of useless 1kb tiles. It appears as if the PNGs coming out of GeoWebCache are 32 bit. I thought these might work, and they are great in my extents, but I can't have these "black"/shadow areas if you want to like a tan line on a beach. This should be a Microsoft Silverlight problem that needs to be fixed on their side.

Could make the transparent tile configurable. Feel free to file a feature request ticket on geowebcache.org -Arne Mark Rodrigo wrote: > I need a better solution than just increasing my extents...

Maybe, try this: You can unpack geowebcache.jar , look for blank.png, replace it with another PNG and repack. -Arne Roger Bedell wrote: > I filed this feature request. Thanks!

To replace the default 8 bit blank.png with the attached 24bit blank png, In the directory where geowebcacahe-1.1.0.jar lives, create a subdirectory org/geowebcache Put the attached png there and name it blank.png Update the jar: jar uf geowebcache-1.1.0.jar org/geowebcache/blank.png Test it by extracting and seeing if it is the new one (it is 662 bytes, the old one is 129 bytes) jar xf geowebcache-1.1.0.jar org/geowebcache/blank.png You will need to clear your browser cache to see the difference in the Silverlight map control. It worked for me...
