I have published an ImageService from a mosaïc on an ArcGIS Server (10.7). Original data are 4 bits GRID rasters.
The mosaic stores pixels values on 4 bits. Only values from 0-8 are used so I have max 9 unique values.
I add the raster to the map and then I want to symbolize it using unique values.
Here is the server response from the 'histograms' REST endpoint
All values seem to be present. Though the proposed symbology below shows 2 times the value 4 and doesn't shows the value 7
Has someone ever encountered this behavior ? How can it be fixed ?
