Combine the given Tile with the present one using the given function.
Combine the given Tile with the present one using the given function.
Combine the given Tile with the present one using the given function.
Combine the given Tile with the present one using the given function.
Converts the cell type of the tile.
Converts the cell type of the tile.
This will immediately iterate over the tile and allocate a new copy of data; this should be a performance consideration.
Reduce the resolution of the present Tile to the given number of columns and rows.
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.
The tile to combine with the present one
The integer function
The double function
Execute a function at each pixel of a Tile.
Map one of the two given functions across the Tile to produce a new one.
Conditionally map across the Tile with one of two functions, depending on whether the tile is an integer- or a floating-tile.
Return tuple of highest and lowest value in raster.
Return tuple of highest and lowest value in raster.
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.
Return tuple of highest and lowest value in raster.
Execute the given function at each pixel of the present Tile.
Execute the given function at each pixel of the present Tile.
Execute the given function 'f' at every location in the tile.
Execute the given function 'f' at every location in the tile. The function 'f' takes the column, row, and value and returns nothing (presumably for side-effects).
Execute the given function at each pixel of the present Tile.
Execute the given function at each pixel of the present Tile.
Execute the given function 'f' at every location in the tile.
Execute the given function 'f' at every location in the tile. The function 'f' takes the column, row, and value, the last one as a double, and returns nothing (presumably for side-effects).
Get value at given coordinates.
Get value at given coordinates.
Get value at given coordinates.
Get value at given coordinates.
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.
CellType to be used in interpreting existing cells
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
.
Map over the tiles using a function which accepts the column, row, and value at that position and returns an integer.

Conditionally execute (or don't) the given function at each pixel of a Tile, depending on whether that pixel is NODATA or not.

Returns a mutable instance of this tile.
Returns a mutable instance of this tile.
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.
