Return tuple of highest and lowest value in raster.

- Note
Currently does not support double valued raster data types (FloatConstantNoDataCellType, DoubleConstantNoDataCellType). Calling findMinMax on rasters of those types will give the integer min and max of the rounded values of their cells.

foreach(f: (Int, Int, Int) ⇒ Unit): Unit

interpretAs(newCellType: CellType): Tile
Changes the interpretation of the tile cells through changing NoData handling and optionally cell data type.
Changes the interpretation of the tile cells through changing NoData handling and optionally cell data type. If DataType portion of the CellType is unchanged the tile data is not duplicated through conversion. If cell DataType conversion is required it is done in a naive way, without considering NoData handling.

map(f: (Int) ⇒ Int): Tile
Map the given function across the present Tile.
Map the given function across the present Tile. The result is another Tile.
Values can also be mapped with "class-break logic":
import geotrellis.raster.render.BreakMap // Maps break values to result values val m: Map[Int, Int] = ... val t: Tile = ... // BreakMap extends `Function1` t.map(BreakMap.i2i(m))
If
Tileabove had an underlying floating CellType, then the transformation would effectively be fromDouble => Int.- Definition Classes

When the underlying class is an instance of MutableArrayTile it will return itself without performing a copy. This is used internally as a performance optimization when the ownership of the tile is controlled.
