Distance Field#
- rforge.library.processes.distance.distance(layer: Layer | ndarray, alpha: Layer | ndarray | None = None, thresholds: list | tuple | None = None, invert: bool = False, mask_size: int = 3, as_array: bool = False) ndarray | Layer[source]#
Calculate the distance field of a geographical region.
- Parameters:
layer – Binary layer data.
alpha – Alpha layer. Defaults to None.
thresholds – Thresholds to use for image binarization. Defaults to None.
invert – If True, inverts the binary layer data before processing. Defaults to False.
mask_size – Size of the mask for distance calculation. Defaults to 3.
as_array – If True, returns the distance field as a Numpy array. Defaults to False.
- Returns:
Distance field layer.
- Raises:
TypeError – If inputs are not of the accepted type.
