Hi all,
Can Geoserver generate WMS maps in grayscale from 3-bands (RGB) geotiff layer?
Geoserver generates well color tiles from this geotiff by using the default
raster SLD, but would it be possible to use the same geotiff for generating
grayscale maps?
I know GDAL_CALC van transform 3-band RGB geotiff to 1-band grayscale geotiff,
but I would prefer using a single 3-bands geotiff to produce both color and
grayscale maps (by using different SLD or SLD rules.
Is it possible?
Many thanks,
Victor
