Is it possible to request an image from an ImageServer service and have an existing raster function applied to it? We have several pre-defined functions available, as shown by the rasterFunctionsInfo REST endpoint. I can't find any documentation on how to do this. I've tried sniffing the connection from arcMap using Fiddler but it doesn't seem to be able to decrypt the POSTed data into a usable format so I can see the syntax being used.
Has anyone been able to do this successfully and can share how they did it?
