Hi,
I'm publishing a mosaic dataset with a raster function from ArcGIS Pro 2.8 to Portal 10.9 federated server as ImageService and register the service to the portal.
If I investigate the mosaic dataset with attached raster function in Pro I get the correct classification with the first class as transparent.
But if I load the published image service into portal map viewer, the first class becomes white and I have to set it manually to "no color".
My overall process is completely automated so this is no option.
How can I get portal to understand the first class color map to be "no color"?
Thank you for your help!
