Hi.
We have an Enterprise 11.1 single machine base installation with one additional federated AGS with the Image server role.
Using https://developers.arcgis.com/rest/services-reference/enterprise/download-rasters/ it seems that if the rasters in the mosaic dataset published as an image service are a tiled orthofoto (with 500 + tiles) then if we have a request that specifies an image `format` and a clipping geometry that entirely covers a tile/raster, then that tile/raster will not be converted and the reference to it will be to the original tile (suitable for downloading with the Raster File method) but all rasters/tiles that would be clipped are clipped and converted (and in temporary arcgisoutput folders linked).
1. Is this the intended behaviour? We can get everything within the clipping geometry converted via the `:Conversion` suffix to the `format` however it would to me see as if that functionality is implied when you are supplying a `format` param and a clipping geometry.
2. Since the orthofoto original image is made up out of many tiles if the clipping geometry is quite large then the response to Download Raster will be a rather long list of georeferenced and clipped/converted rasters. I get that clip means clip, it does not mean clip and merge, so do people usually prepare the source raster in the mosaic when intending to use the Download Raster operation? In our case it seems like the operation would work better if the source mosaic dataset consisted of one big tiff.
Or is it more popular to process the output of the Download Raster operation? In our case let FME or something mosaic the clipped tiles into one raster with the shape of the clipping geometry (it comes with a couple of drawbacks in what readers and writers are available in FME for instance. The Download Rasters operation can produce a whole slew of image formats so it seems to me it would be best if we didn't have to mosaic the result with FME and save it with a writer but could rather expose the rasters that Image server produces to the user)
