Hello,



               I have added an ArcGIS Image service to my QGIS project.  It
represents a DEM for the Province of New Brunswick, Canada.  Here are some
of the details from “Layer Properties > Information”:
------------------------------

*Name*

Elevation/DEM_Raw_MNE_Brut

*URL*

https://geonb.snb.ca/image/rest/services/Elevation/DEM_Raw_MNE_Brut/ImageServer

*Source*

crs='EPSG:2953' format='JPGPNG' url='
https://geonb.snb.ca/image/rest/services/Elevation/DEM_Raw_MNE_Brut/ImageServer
'

*Provider*

arcgismapserver

*allowRasterFunction*

true



               I would like to change the style or rendering of the DEM to
contours, Hillshade, etc.  Is this possible?  I am running QGIS version
3.34.4-Prizren on Windows 11, 64-bit.


        To restyle a local DEM raster I would go to "Layer Properties >
Symbology" and simply change the "Render type" to Hillshade or Contours.
However, the only option available in the "Render type" drop-down list is
"Singleband color data".  I am able to restyle this image service in ArcGIS
Online and in ArcGIS Pro.



Thanks,

Bernie.
