Hi All,
We have some Geotiff rasters with small lines (cables) on it.
Serving these transparent with Geoserver is fine, using
InputTransparentColor set to #ffffff.
But adding pyramids/overviews to it, the lines look better in QGIS, so
we added the pyramids using gdaladdo.
While that works for QGIS, for Geoserver (2.12.0) it looks as if the
InputTransparentColor in the overviews is NOT used?
The map is not transparent anymore, untill you zoom in at the base
level, THEN the map will be transparent again.
Using default raster sld.
Anybody a clue?
Regards,
Richard Duivenvoorde
