  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

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

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

    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

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

    Definition Classes

  10. abstract def get(col: Int, row: Int): Int

    Get value at given coordinates.

  11. abstract def getDouble(col: Int, row: Int): Double

    Get value at given coordinates.

  12. abstract def 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.

    newCellType

    CellType to be used in interpreting existing cells

  13. abstract 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.

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

  17. abstract def mutable: MutableArrayTile

    Returns a mutable instance of this tile.

    Returns a mutable instance of this tile.

    Note

    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.

  18. abstract def rows: Int

    Tile → Grid
  19. abstract def toArray(): Array[Int]

    Return the data behind this Tile, or a copy, as an Array of integers.

  20. abstract def toArrayDouble(): Array[Double]

    Return the data behind this Tile, or a copy, as an Array of doubles.

  21. abstract def toArrayTile(): ArrayTile

    Convert the present Tile to an ArrayTile.

  22. abstract def toBytes(): Array[Byte]

    Return the data behind this Tile, or a copy, as an Array of bytes.

    Combine two Tiles together using one of two given functions.

    Combine two Tiles together using one of two given functions. If the union of the types of the two cells is floating-point, then the floating function is used, otherwise the integer function is used.

    r2

    The tile to combine with the present one

    f

    The integer function

    g

    The double function

  9. def dualForeach(f: (Int) ⇒ Unit)(g: (Double) ⇒ Unit): Unit

    Execute a function at each pixel of a Tile.

    Execute a function at each pixel of a Tile. Two functions are given: an integer version which is used if the tile is an integer-tile, and the other in the case of a floating-tile.

    f

    A function from Int to Unit

    g

    A function from Double to Unit

  10. def dualMap(f: (Int) ⇒ Int)(g: (Double) ⇒ Double): Tile

    Map one of the two given functions across the Tile to produce a new one.

    Return tuple of highest and lowest value in raster.

    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.

    Return tuple of highest and lowest value in raster.

  17. macro def foreach(f: (Int, Int, Int) ⇒ Unit): Unit
