ArcSever Tile Cache: Create Overzoom Effect

[DavidColey]

Hi - I asked this in response regarding a method to prepare a tpk for offline use: How does esri create the 'overzoom' effect for the world topo map service?  Clearly the large scales say past 1:564 are drawing at the same resolution, but I can't figure out how to do that with my own caches.  I thought it would be as simple as copying my largest bundle's LOD into the even larger levels, but that doesn't work.

Does the cache have to be exploded?  Does it matter if the tile format is PNG vs JPEG?  Any suggestions?

Thanks,

David

Sorry, a bit more. Found this link:

Latest ArcGis jsapi library resamples images, this doesn't · Issue #240 · Esri/esri-leaflet · GitHub 

Looks like Tilemap is a custom capability maybe in the form of and SOE that handled a resample of existing tiles when a zoom level encountered a missing tile.  Also looks like any work on it is stopping or has stopped becasue vector tiles will be superceding this method.  

Looks like I'll stop chasing this one......
