Hi all, I have a bunch of hillshades from different year. Typically they do not overlap. For each year, I have configured a seperate ImageMosaic store. The images are tiled tifs, greyscale 8 bit with alpha channel. I am using default raster sld style. The alpha channel is there to make it possible to group different years into layergroups, and to make it possible to show a background map on areas where there is no hillshades.
ImageMosaic creation works good, here is an example picture: <http://osgeo-org.1560.x6.nabble.com/file/n5175211/laser_vinovalo-harmaasavy_vinovalovarjoste_2014.jpg> Here, the grayscale values are as intended. When I create a layergroup, or combine one of the hillshade layers with one another, or any other layer (even the layer itself), the image is significantly brighter: <http://osgeo-org.1560.x6.nabble.com/file/n5175211/harmaasavy_vinovalovarjoste_2014_harmaasavy_vinovalovarjoste_2014.jpg> Environment: GS 2.6.1, racle Corporation: 1.7.0_25 (Java HotSpot(TM) 64-Bit Server VM), Native JAI true, tomcat6. Does anybody have an explanation/solution to my problem?
