Function sdfgen_lib::gen_sdf

pub fn gen_sdf(
    img: &DynamicImage, 
    active: &Vec<[u32; 2]>, 
    from: [u32; 2], 
    to: [u32; 2], 
    id: u32, 
    scale: u32
) -> DynamicImage

Generates a distance field from an image and an active map (obtained from get_active()).

img is the input image,

active the white pixels in the image,

from coordinates where the reading of img starts

to coordinates where the reading of img ends

id simply an identifier for the console log. If this is not important to you just pass 0,

scale the factor of the image read

The mapping of the output is all over the place.
