Examples

import { Matrix } from 'immutable-transform-matrix'
import { isImmutable } from 'immutable'
 
const m1 = new Matrix()
const m2 = m1.translate(10, 20)
 
isImmutable(m1) // true
m1.get('e') // 0
m2.get('e') // 10
 

const transform = new Matrix()
  .scale(2)
  .toString()
 
const ViewPort = () => <g transform={transform} />
