I created a GeoProcessing service (GPServer) which is publishe in ArcGIS Server. The results of this GPServer is a MapServer with a GPRasterDataLayer. The default symbology of the raster is a gray scale palette.
How can I add a new render for this raster in the MapImageLayer? I only achieve to change the opacity and the title.
When I run submitJob() (ArcGIS Maps SDK for JavaScript 4.29) I obtain a MapImageLayer using the function FetchResultMapImageLayer(). How can I change the symbology of the raster from the resulting MapImageLayer?
