Interface ISKImagePyramidTileCache
The internal sync render buffer used by SKImagePyramidController. Stores hot decoded tiles for the render loop.
public interface ISKImagePyramidTileCache : IDisposable- Inherited Members
Remarks
This is a pure in-memory LRU cache — no persistence, no async. Disk caching and other persistent strategies are the responsibility of ISKImagePyramidTileProvider implementations, not this interface.
