Descriptions

args: rast, gridx, gridy, algorithm=NearestNeighbour, maxerr=0.125, scalex=DEFAULT 0, scaley=DEFAULT 0 - Resample a raster by snapping it to a grid. New pixel values are computed using the NearestNeighbor (english or american spelling), Bilinear, Cubic, CubicSpline or Lanczos resampling algorithm. Default is NearestNeighbor.
