Dear list, we're currently upgrading Geoserver from 2.22.2 to a current version. In our setup we have an image pyramid data source with multispectral satellite images (5 Band UInt16). Starting from Geoserver 2.22.4 the WMS renders only black images for the image data. I couldn't find a clue which could be the cause for that in the release notes: https://github.com/geoserver/geoserver/releases/tag/2.22.4
Geoserver is running on a linx system with OpenJDK 11 and Tomcat 9. We're using following SLD for the rendering: <?xml version="1.0" encoding="UTF-8"?><sld:StyledLayerDescriptor xmlns="http://www.opengis.net/sld"; xmlns:sld="http://www.opengis.net/sld"; xmlns:gml="http://www.opengis.net/gml"; xmlns:ogc="http://www.opengis.net/ogc"; version="1.0.0"> <sld:NamedLayer> <sld:Name>RGB</sld:Name> <sld:UserStyle> <sld:Name>RGB</sld:Name> <sld:FeatureTypeStyle> <sld:Rule> <sld:Title>rgb</sld:Title> <RasterSymbolizer> <Opacity>1.0</Opacity> <ChannelSelection> <RedChannel> <SourceChannelName>3</SourceChannelName> </RedChannel> <GreenChannel> <SourceChannelName>2</SourceChannelName> </GreenChannel> <BlueChannel> <SourceChannelName>1</SourceChannelName> </BlueChannel> </ChannelSelection> </RasterSymbolizer> </sld:Rule> <sld:VendorOption name="ruleEvaluation">first</sld:VendorOption> </sld:FeatureTypeStyle> </sld:UserStyle> </sld:NamedLayer> </sld:StyledLayerDescriptor> I already tried ContrastEnhancement with StretchToMinimumMaximum for the channels but without success. Do you have any hints what could cause the problem and how to solve it? Kind regards, Dirk
