I develop a WebGIS application with a GIS Framework called Geomajas. I use GeoServer to integrate raster data like WMS on my application.
My raster is a big tiff (4Go), so I've built image pyramid with the pyramid plugin. I's work and I can see my raster like a WMS on the OL application.
I configure this WMS on my geomajas applicatin but when I try to display it on my application, Raster quality is different between tiles (cf screenshot in attachment). On Firebug, the individual images look the same than the geomajas application.
I asked the question to the geomajas developers but they told me that's a problem on geoserver side. I don't know if somebody has already have this sort of problem?
