API

intersectPathData

Given 2 strings which are svg d-attributes, returns the d-attribute for the intersection of the two paths

subtractPathData

Given 2 strings which are svg d-attributes, returns the d-attribute for the difference of the two paths

Usage

const { intersectPathData, subtractPathData } = require('lib2geom-path-boolean-addon');
 
const intersection = intersectPathData('M0,0 L10,0 L10,10 L0,10 Z', 'M5,5 L15,5, L15,15 L5,15 Z');
 
const subtraction = intersectPathData('M0,0 L10,0 L10,10 L0,10 Z', 'M5,5 L15,5, L15,15 L5,15 Z');
