  3. abstract def combine(r2: Tile)(f: (Int, Int) ⇒ Int): Tile

    Combine the given Tile with the present one using the given function.

  4. abstract def combineDouble(r2: Tile)(f: (Double, Double) ⇒ Double): Tile

    Permalink

    Combine the given Tile with the present one using the given function.

  5. abstract def convert(cellType: CellType): Tile

    Permalink

    Converts the cell type of the tile.

    Converts the cell type of the tile.

    Note

    This will immediately iterate over the tile and allocate a new copy of data; this should be a performance consideration.

  6. abstract def foreach(f: (Int) ⇒ Unit): Unit

    Execute the given function at each pixel of the present Tile.

  7. abstract def foreachDouble(f: (Double) ⇒ Unit): Unit

  12. abstract def interpretAs(newCellType: CellType): Tile

    Permalink

    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.

    newCellType

    CellType to be used in interpreting existing cells

  13. abstract def map(f: (Int) ⇒ Int): Tile

    Permalink

    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.

  14. abstract def mapDouble(f: (Double) ⇒ Double): Tile

    Permalink

    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[Double, Double] = ...
    val t: Tile = ...
    
    // BreakMap extends `Function1`
    t.mapDouble(BreakMap.i2i(m))

    If Tile above had an underlying integer CellType, then the transformation would effectively be from Int => Double.
