TiledImageTileId

data class TiledImageTileId(val level: Int, val column: Long, val row: Long)(source)

Identifies one tile in a source-owned resolution level.

Columns and rows use the mathematical grid whose origin is content coordinate zero. Negative content coordinates therefore map with floor division rather than truncation toward zero. The identifier is meaningful only with the identity of its TiledImageSource.

Throws

IllegalArgumentException

when TiledImageTileId.level is negative.
