Computes the intersection between two SVG paths.
Execute npm run dev and navigate to http://localhost:9876/debug.html to see more examples.
import intersect from 'path-intersection'; const path0 = 'M30,100L270,20'; const path1 = 'M150,150m0,-18a18,18,0,1,1,0,36a18,18,0,1,1,0,-36z'; const intersection = intersect(path0, path1); // [ { x: ..., y: ..., segment1: ..., segment2: ... }, ... ]Results are approximate, as we use bezier clipping to find intersections.
Where performance matters, you can pre-parse paths and cache them:
import intersect, { parsePath } from 'path-intersection'; // parse paths once const path1 = parsePath('M0,0L100,100'); const path2 = parsePath('M0,100L100,0'); // they won't be re-parsed during intersection checking const result1 = intersect(path1, path2); const result2 = intersect(path2, path2);For repeated calculations, this optimization can result in substantial performance improvements.
