Is it possible to identify the pixel values of a Raster that is published in a map service? Or an image service needs to be published for querying pixel values of a raster..

I have different raster data that needs to be served in an ArcGIS Server. The pixel values of the the raster data needs to queried/identified on a mouse click from a web application through ArcGIS API for JavaScript ( not necessarily  the raster needs to be added in the map). What would be the best approach towards this issue?

 

Is it possible to identify the pixel values of a raster layer from a map service using IdentifyTask (ArcGIS API for JavaScript)?

 

Or Can pixel values be queried only through a image service? If both are feasible which would be a better approach.

 

Thank you.
