Scaling tiles after supported zoom levels

[DrYSG]

I am using Leaflet for offline Map viewing (see my demo of using PouchDB for offline tile storage at: http://gis.stackexchange.com/questions/62070/offline-slippy-map-tiles-database-for-leaflet/62073#62073 )

As a base layer I am using the NASA BlueMarble image. The full scale image at 8 levels of zoom is "only" 186MB, 43K tiles of JPG. I would like to generate this to 10 or 11 zoom levels, but it is too heavy for offline.

But for my use case (as a backdrop for a few selected small footprint aerial photos at zoom 11) it would be fine to just zoom the level 8 zoom pixels. (users don't care about grainy backdrops, just full res aerials).

Does this sound like a reasonable request for the core product?

Someone did suggest I look at: ZoomTMSLayer: https://github.com/tilemapjp/ZoomTMSLayer but I do not have TMS layers. What I have are EPSG4326 LL84 tiles in a PouchDB database, and I am using the FunctionalLayer plugin for leaflet to display.

Yep, totally makes sense, I'll look at it — shouldn't be too hard to implement, thanks!

@DrYSG check out the pull request above! I had this feature in mind a long ago but only now realized that it was very easy to implement so I should do it now. :)

Exactly what we are looking for. Thank you very much.

Not working with detectRetina=true. I'm trying to use this with options {tms: true, detectRetina: true, maxZoom: 15, maxNativeZoom: 14} and I only get 13 zoom levels.

@omjokine thanks, will check this out
