Hi,
We need to be able to provide a grayscale version of one of our map layers,
however there isn’t an obvious way to do this. It easy to produce a single-band
grayscale image, e.g.:
<RasterSymbolizer>
<Opacity>0.6</Opacity>
<ChannelSelection>
<GrayChannel>
<SourceChannelName>1</SourceChannelName>
</GrayChannel>
</ChannelSelection>
</RasterSymbolizer>
However I need to include all bands. Is there a way to do this using an SLD
without pre-processing the data? The image is RGB.
Thanks,
Jon
