I am trying to render an 8 bit GeoTIFF (4 Band) on GeoServer and I am having troubles rendering the image on an WMS service.
When I zoom out the image, it gets pixelated:
Below, it is the same GeoTiff in QGIS with same scale (1:100000)
The image rendered by GeoServer is extremely pixelated. I tried tweaking the configuration but I could not reach the same level of quality as it is shown in QGIS.
The version of GeoServer we are using is the 2.2.4. Could someone give me a hint about what may be causing such pixelation on GeoServer?
