9. def foreachCellByGeometry(geom: Geometry, re: RasterExtent, options: Options)(f: (Int, Int) ⇒ Unit): Unit

   

   Perform a zonal summary by invoking a function on each cell under provided features.

   Perform a zonal summary by invoking a function on each cell under provided features.

   This function is a closure that returns Unit; all results are a side effect of this function.

   Note: the function f should modify a mutable variable as a side effect. While not ideal, this avoids the unavoidable boxing that occurs when a Function3 returns a primitive value.

   geom

   Feature for calculation

   re

   RasterExtent to use for iterating through cells

   options

   Options for the (Multi)Polygon and Extent rasterizers

   f

10. def foreachCellByGeometry(geom: Geometry, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Given a Geometry and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry.

11. def foreachCellByLineString(line: Line, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Iterates over the cells determined by the segments of a LineString.

    Iterates over the cells determined by the segments of a LineString. The iteration happens in the direction from the first point to the last point.

12. def foreachCellByMultiLineString(g: MultiLine, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Apply function f to every cell contained within MultiLineString.

    f

    Function to apply: f(cols, row, feature)

13. def foreachCellByMultiPoint(p: MultiPoint, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Given a MultiPoint and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry.

    Given a MultiPoint and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry. The two arguments to the function 'f' are the column and row.

14. def foreachCellByMultiPolygon[D](p: MultiPolygon, re: RasterExtent, options: Options)(f: (Int, Int) ⇒ Unit): Unit

    

    Apply function f to every cell contained with MultiPolygon.

    Apply function f to every cell contained with MultiPolygon.

    p

    MultiPolygon used to define zone

    re

    RasterExtent used to determine cols and rows

    options

    The options parameter controls whether to treat pixels as points or areas and whether to report partially-intersected areas.

    f

    Function to apply: f(cols, row, feature)

15. def foreachCellByMultiPolygon[D](p: MultiPolygon, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Given a MultiPolygon and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry.

    Given a MultiPolygon and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry. The two arguments to the function 'f' are the column and row.

16. def foreachCellByPoint(geom: Point, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Invoke a function on raster cells under a point feature.

    Invoke a function on raster cells under a point feature.

    The function f is a closure that should alter a mutable variable by side effect (to avoid boxing).

17. def foreachCellByPointSeq(pSet: Seq[Point], re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Invoke a function on each point in a sequences of Points.

18. def foreachCellByPolygon(p: Polygon, re: RasterExtent, options: Options)(f: (Int, Int) ⇒ Unit): Unit

    

    Apply function f(col, row, feature) to every cell contained within polygon.

    Apply function f(col, row, feature) to every cell contained within polygon.

    p

    Polygon used to define zone

    re

    RasterExtent used to determine cols and rows

    options

    The options parameter controls whether to treat pixels as points or areas and whether to report partially-intersected areas.

    f

    Function to apply: f(cols, row, feature)

19. def foreachCellByPolygon(p: Polygon, re: RasterExtent)(f: (Int, Int) ⇒ Unit): Unit

    

    Given a Polygon and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry.

    Given a Polygon and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry. The two arguments to the function 'f' are the column and row.

20. def foreachCellInGridLine[D](x0: Int, y0: Int, x1: Int, y1: Int, p: Line, re: RasterExtent, skipLast: Boolean = false)(f: (Int, Int) ⇒ Unit): Unit

    

    Implementation of the Bresenham line drawing algorithm.

    Implementation of the Bresenham line drawing algorithm. Only calls on cell coordinates within raster extent.

    The parameter 'skipLast' is a flag which is 'true' if the function should skip function calling the last cell (x1, y1) and false otherwise. This is useful for not duplicating end points when calling for multiple line segments.

    p

    LineString used to define zone

    re

    RasterExtent used to determine cols and rows

    skipLast

    Boolean flag

    f

    Function to apply: f(cols, row, feature)
