Hello,
I have custom geoTiff, I sliced it to tiles and I use
BaseTileLayer.createSubclass -> getTileUrl for loading these tiles to a separate layer
If some tiles are missing my API server will return 404,
I have tiles for 18 zoom level max
If I will zoom, it works fine - an image will scale, even to 23 level, this is great!
But, if I will move my extent I will see just a default Esri map,
also, if I will move my extent back - the scaled tile is gone.
Is it possible to "cache" loaded images and load scaled parts when it's necessary(on 404 error)?
So far I'm picturing something like - an interceptor that will save all images, then figure out how to translate tile coordinates between different zoom levels and use some particular cached image.
