  2. type Segment = (Double, Double, Double, Double)

Value Members

  1. def foreachCellByPolygon(poly: Polygon, re: RasterExtent, options: Options = Options.DEFAULT)(f: Callback): Unit

    This function causes the function f to be called on each pixel that interacts with the polygon.

    This function causes the function f to be called on each pixel that interacts with the polygon. The definition of the word "interacts" is controlled by the options parameter.

    poly

    A polygon to rasterize

    re

    A raster extent to rasterize the polygon into

    options

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

  2. def polygonToEdges(poly: Polygon, re: RasterExtent): STRtree

    Given a polygon and a raster extent, return an R-Tree (being used as an Interval Tree) containing the Segments -- in raster coordinates -- that comprise the boundary of the polygon.

    poly
