    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.

    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.

  35. def 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 Tile above had an underlying floating CellType, then the transformation would effectively be from Double => Int.
