A type encoding rasterizer options.
A companion object for the Options type.
A companion object for the Options type. Includes a function to produce the default options settings.
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.
Feature for calculation
RasterExtent to use for iterating through cells
Options for the (Multi)Polygon and Extent rasterizers
A function that takes (col: Int, row: Int) and produces nothing
Given a Geometry and a RasterExtent, call the function 'f' at each pixel in the raster extent covered by the geometry.
Given a Geometry 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.
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.
Iterates over the cells determined by the segments of a LineString.

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.
