svg-path-sdf

Create signed distance field for an svg path data.

Usage

let pathSdf = require('svg-path-sdf')

let arr = pathSdf('M40,0A40,40 0 1,1 0,-40A40,40 0 0,1 40,0Z', {
	width: 200,
	height: 200
})

arr has 200×200 elements with value from 0..1 range, corresponding to distance. The path is drawn at the center of the sdf fitting to the minimum side.

distances = pathSdf(path, options|shape?)
