fabric/dist/src/ClassRegistry.mjs

Object model for HTML5 canvas, and SVG-to-canvas parser. Backed by jsdom and node-canvas.

import { FabricError } from './util/internals/console.mjs';

/*
 * This Map connects the objects type value with their
 * class implementation. It used from any object to understand which are
 * the classes to enlive when requesting a object.type = 'path' for example.
 * Objects uses it for clipPath, Canvas uses it for everything.
 * This is necessary for generic code to run and enlive instances from serialized representation.
 * You can customize which classes get enlived from SVG parsing using this classRegistry.
 * The Registry start empty and gets filled in depending which files you import.
 * If you want to be able to parse arbitrary SVGs or JSON representation of canvases, coming from
 * different sources you will need to import all fabric because you may need all classes.
