Hello,
I am using Geoserver 2.4.1 (Linux CentOS 6.4) and I have problem to
properly setup transparency parameters for my mosaic. The mosaic is
based on 8bits GeoTIFFs:
Driver: GTiff/GeoTIFF

341.234.164.tfw

Event thought the rasters are 8bit only two colors are used: white for a
background and black for raster data.
Rasters overlaps and with default layer settings and basic 'raster'
style I can see white strips at the borders of rasters. According to a
documentation I tried to set InputTransparentColor to #FFFFFF (white
color) to make rasters transparent and avoid the strips but as a result
I got completely black mosaic.
Is there something more I should do with layer configuration? Maybe
rasters are wrong?
Best regards
